Lead Markers For Clinical Education

Lead Markers

Lead markers for radiography are also known by a number of different names including Pb markers, X-ray markers, anatomical side markers, and radiographic film identification markers. Lead markers are used to mark X-ray films in hospitals, clinics, and other healthcare facilities. Most lead markers come color-coded to denote right and left on X-ray or radiographic images to assist the radiographer or radiologic technologist on identifying the right and left side of the body. The lead markers will generally have a letter R for the right and the letter L for the left as well as the radiologic technologist (R.T.s) initials.

Radiologic Technology Program

When students are admitted into a radiologic technology program it can be overwhelming at first. There are a number of important things that you have to take care of before your first day of class. You will have to schedule a physical and get your immunizations before you can start your clinical. After you have taken care of your immunizations you can look forward to picking out your clinical attire usually including white shoes, division scrubs, name tag, lead markers, and radiation monitor.

Required Equipment

All radiologic labs require students to have their radiation monitoring badge (radiation dosimeter), lead markers, and name tags before entering the X-ray laboratory. Many programs will consider the student out of acceptable uniform if they show up to their clinical assignment without his or her personalized lead makers. Lead markers are very important when performing procedure evaluations and must be used on all images of the exam. Generally an explanation of the use of any other markers must be noted on the procedure evaluation form by the technologist. Most programs require the student to keep a record of all the examinations he or she assists in a performs in a daily clinical log book. The total number of procedures participated in by the student must be recorded on a tally sheet or “tallies”  that is submitted at the end of each semester. School policies usually require the student’s personalized lead marker to be present on the film to be marked “performed”, please check with your school for specific course information.

Program Specific Requirements for Lead Markers

Many programs will have explicit rules in place regarding the use of lead markers. It is common practice to require the student to purchase their own set of markers before starting the program although some schools provide lead markers for their students. Lead markers are usually customized with the students initials and thereby used to identify which procedure was performed by the student. Schools will usually hold the student responsible for all radiographs bearing their markers so it is important to notify the clinical coordinator immediately if markers are lost.


Check with your school or program to determine what policies are applicable to you. Upon acceptance, most programs will send you a welcome packet or handbook with detailed information regrading program information. Congratulations and good luck on your journey!

How To Choose The Right Disposable Shoe Covers

Disposable shoe covers fall under the category of PPE or personal protective equipment. The World Health Organization states that using personal protective equipment provides a physical barrier between micro-organisms and the wearer. It offers protection by helping prevent microorganisms from contaminating hands, eyes, clothing, hair, and shoes. PPE also helps prevent micro-organisms from being transmitted to other patients and staff. It is important to remember that personal protective equipment reduces but does not completely eliminate the risk of acquiring an infection.

In the World Health Organization publication “Practical Guidelines for Infection Control in Health Care Facilities” it states that disposable shoe covers should be worn where there is the likelihood the patient’s blood, bodily fluids, secretions or excretions may splash, spill or leak onto the hair or shoes. Disposable shoe covers should not be reused and should be discarded according to the healthcare facility protocol.

When selecting a disposable shoe cover you will want to consider the material, type of seam and application. When selecting disposable shoe covers there are several material options available to choose from including all film CPE (Chlorinated Polyethylene), SureGrip™, GenPro®, and AquaTrak®.

Material Properties & Applications

  • The CPE shoe covers are heat sealed, seamless and offer excellent fluid resistant and provide great dry surface traction. These non-particulate, non-conductive disposable shoe covers are ideal for critical environments by reducing the potential of contamination upon entering work areas.
  • The SureGrip™ shoe cover exhibits excellent anti-skid properties and is simply the best material for damp and dry conditions. These disposable shoe covers have an ultra low particulate count and exhibit excellent anti-skid properties without adding any extra material to the sole that could add to contamination concerns.
  • The AquaTrak® material provides excellent protection in both wet and dry conditions, this material was designed specifically for superior performance in wet conditions. The anti-skid properties provide amazing slip and fall protection without any additional coatings. These boot covers provide the user a breathable and comfortable PPE solution.

Seam Types

  • Serged Seams are produced when the threads are interlocked around the material edges for a strong stress-resistant seam.
  • Heat-Sealed Seams are strong and creates an impervious seam when ultra-sonic welding is incompatible with the shoe or boot cover material.
  • Ultrasonically Welded Seam are created without thread holes and is welded together creating a superior particle and fluid barrier.
  • Tunneled Elastic Seam design provides a secure closure for the shoe or boot cover and helps limit the particle and fluid contamination.

The Benefits Of Selecting The Right Urology Drainage System

Urology is the branch of medicine that focuses on the surgical and medical diseases of the male and female urinary tract system as well as the male reproductive organs. The organs that are included under the domain of urology includes the adrenal glands, kidneys, male reproductive organs, urinary bladder, ureters,  and urethra.  The reproductive and urinary tracts are closely connected and disorders of one often impact the other. Many of the conditions managed in urology can be categorized under genitourinary disorders. Urology combines the medical management of disease (i.e. urinary tract infection) to the management of surgical conditions ranging from bladder or prostate cancer to kidney stones, congenital abnormalities, traumatic injury to stress incontinence.

 Seven Subspecialties 

The American Urologic Association (AUA), governing body for the specialty has divided Urology into seven subspecialties.

  • Oncology: The surgical treatment of malignant genitourinary diseases such as cancer of the prostate, adrenal glands, bladder, kidneys, and testes.
  • Calculi: Medical, endoscopic, extracorporeal, percutaneous, and surgical management of stones of the urinary tract.
  • Female Urology: Medical and surgical management of incontinence and pelvic outlet relaxation disorders.
  • Infertility:  Medical and surgical management of male infertility.
  • Pediatrics: Medical and surgical management of urological disease in the pediatric population.
  • Transplant: Renal transplantation or kidney transplantation
  • Neurourology: The study of how the nervous system affects the urinary system. Neurological diseases and conditions such as multiple sclerosis, Parkinson’s disease, stroke and spinal cord injury can disrupt the lower urinary tract and result in conditions such as urinary incontinence and the inability to urinate.


Urology Drainage Systems

When a patient undergoes a urological surgical procedure it is important to ensure that the patient is comfortable and protected. Whether a patient is undergoing a cystoscopy procedure, hysterectomy or other urological procedures, a urology drainage system is essential for ensuring the patient’s comfort, hygiene, and health. Drainage systems also help create a more favorable working environment for medical personnel during surgery. When selecting a urology drainage system and components it is important to consider some of the benefits of choosing the right system for your needs.

Determining Electroporation Cuvette Gap Size

In our last post on electroporation we discussed the basics of electroporation. The focus of this post will be on determining the correct gap size for electroporation cuvettes. Electroporation cuvettes are disposable cuvettes with aluminum electrodes for the electroporation of eukaryotic cells, bacteria, and yeasts. Electroporation cuvettes are generally available in three different sizes with gap sizes or gap widths of 1mm, 2mm, 4mm. The electroporation cuvettes are sterilized with gamma radiation and are individually wrapped to guarantee sterility. Disposable electroporation cuvettes help save time and eliminate the possibility of carryover contamination. The cuvettes are available in three different sizes with filling volumes of 100 µl  microliters for the white capped 1 mm gap size, 400 µl microliters for the blue capped 2 mm gap size, and 800 µl  microliters for the red capped 4 mm  gap size electroporation cuvette.

Electroporation Cuvette DescriptionGap Width Filling Volume μl (microliters)Cell Types
1 mm Gap Sterile Electroporation Cuvette1 mm (White Cap)100 μl Bacteria
2 mm Gap Sterile Electroporation Cuvette2 mm (Blue Cap)400 μl Yeast
4 mm Gap Sterile Electroporation Cuvette4 mm (Red Cap)800 μl Mammalian Cells

The gap size is the distance between the electrodes and is important when optimizing your electroporation experiment. Gap size is used when determining the field strength (kV)  by using the formula of voltage divided by gap size (cm). If the desired field strength and gap size is known you can also determine what the appropriate voltage would be required to successfully perform the experiment. 

Optimization for electroporation takes many different factors into consideration and determining the cuvette gap size is only one consideration of optimizing the experiment. We will be discussing other optimizations in upcoming posts next year so be sure to subscribe to our blog to stay informed with new updates.

Whiteboard Wednesday: Sterile Ultrasound Gel For Infection Control

Today on our Whiteboard Wednesday series, we discuss why sterile ultrasound gel is better when it comes to infection control.  Watch here to find out why:

What’s The Difference Between Ultrasound Gel And Ultrasound Lotion?

Ultrasound-based diagnostic imaging or ultrasonography uses high-frequency sound waves to visualize soft tissues such as muscles and internal organs. Obstetric sonography is the practice of examining pregnant women using ultrasound and is widely used. Sonograms or ultrasound images are made by sending a pulse of an ultrasound into tissue using an ultrasound transducer or probe. As the sound reflects off various parts of  body structures the echo is recorded by the computer and displayed as an image on the monitor for the operator.

Ultrasound Technology

Ultrasound technology is used to create various types of images. Perhaps the most common type of ultrasound image, is the B-mode image or the 2-D cross-section of the tissue being imaged. Creating an image from a sound wave requires three steps, producing the sound wave, receiving the echoes, and forming the image. While producing the sound wave, it is important that the transducer is able to efficiently transmit the sound waves into the body to produce a accurate image. The transducer or hand-held probe, frequently has a soft, pliable, rubber coating that is used to guide the instrument across the area of interest, the skin will then be coated with an aqueous gel to effectively transmit the range of ultrasound frequencies being used (typically between 2 to 18 megahertz).

Ultrasound Gel

At the beginning of an ultrasound exam or procedure, an ultrasound gel is placed on the patient’s skin. Ultrasound gel or a coupling agent, utilizes a basic physics principle where sound waves tend to carry very well through an aqueous or watery medium. When applied to the surface of the patient’s skin, the ultrasound gel acts as a coupling medium and enhances the transmission of ultrasonic sound waves from the skins surface to the head of the ultrasound transducer. Ultrasound gel serves as a lubricant and improves the acoustic transmission of sound waves to the create the image for the sonographer to examine on the monitor. Listed in the table below are a sampling of the different types of ultrasound gels and lotions available and their main product features.

Ultrasound Gel & Ultrasound Lotion

SCAN Ultrasound GelWhen a less viscous gel desiredUnique Dual-ViscosityNo8 ounce, 1 US Gallon
Polysonic Ultrasound LotionWhen lotion is preferred High-ViscosityNo1 US Gallon

Therapeutic Ultrasound 

Ultrasounds can also be used for therapeutic treatment, which refers to any ultrasonic procedure that uses ultrasounds for a therapeutic benefit. A therapeutic ultrasound is a technique that uses sound waves to stimulate tissue under the skin’s surface. These ultrasound techniques can include physical therapy, pain management and a variety of other treatments used in rehabilitation centers. Depending on the type of treatment, the ultrasound stimulates the patient’s subcutaneous tissue using high-frequency sound waves. Therapeutic ultrasounds can create heating effects, increase tissue relaxation, increase blood flow to reduce swelling and inflammation and breakdown scar tissue. Therapeutic ultrasound treatments include a variety of pain management therapies such as chronic pain, muscle strain, muscle tension, tendon injuries, and many more.

Ultrasound Lotion

At the beginning of a therapeutic ultrasound treatment, ultrasound lotion is applied to the area of the patient’s body that is being treated. The probe from the ultrasound machine will then circulate the ultrasound lotion against the area of the patient. Similar to how ultrasound gel in diagnostic imaging is important, ultrasound lotion for therapeutic ultrasound treatments is equally as important. Ultrasound lotion is easily absorbed by the skin while ultrasound gel has is water soluble and is removed after the exam or procedure. Ultrasound lotion is often preferred by medical staff and patients for therapeutic ultrasound treatments due to the rich, moisturizing formula. The ultrasound lotion is acoustically correct for a broad range of frequency transducers and is hypoallergenic and bacteriostatic.

Weekly Wrap For December 9 – December 13, 2013

What Is Electroporation?

Electroporation is the application of an electric current to a living surface (as the skin or a cell membrane) in order to open pores or channels through which something (as a drug or DNA) may pass.  Electroporation or electropermeabilization is usually used in molecular biology as a way of introducing some substance into a cell, such as loading it with a molecular probe, a drug that can change a cell’s function, or a piece of coding DNA.

Freezing Tissue For Frozen Section Diagnosis

When performing a frozen section procedure (also known as cryosection), it’s important to use the appropriate tools and chemicals. Throughout this process an aerosol refrigerant is sprayed to freeze the sample and expedite the freezing process. Frozen section procedures are referred to as pathological laboratory procedures that performed often in oncological surgery.

Whiteboard Wednesday: The Benefits Of Wearing Exam Gloves

This week’s Whiteboard Wednesday we highlight the benefits of wearing medical exam gloves in your facility! Exam gloves are ideal for many reasons, protecting hands from infection and germs, keeping in line with infection control standards, being able to use them in many different types of  procedures and applications, etc.

Featured Product: Chemo Sharps Container

A needlestick from a contaminated sharp has the possibility of leaving a worker infected with HIV, HBV, HCV and other dangerous pathogens. It’s important to appropriately discard sharps in your facility’s designated sharps containers. When selecting sharps containers it’s good to know the type of waste your facility has to discard, the storage area and space limitations and your facility’s state and federal regulations.
