In today's advanced medical imaging field, the use of x-ray positioning aids is crucial for obtaining accurate and clear diagnostic images. These aids come in a variety of types, each serving a specific purpose in ensuring optimal positioning of patients during imaging procedures. Let's take a closer look at the diverse world of x-ray positioning aids and explore the range of options available to healthcare professionals.
Coated VS Non-Coated Foam Positioning Aids
Non-coated foam is essentially a raw piece of foam shaped for specific purposes. It can be compared to a typical kitchen sponge in that it lacks a protective coating, is porous (absorbing liquids), and is not particularly durable. However, one advantage that non-coated foam does have is its cost-effectiveness. These uncoated foam positioners are essential in certain applications and facilities that require only the basic functionality of foam at a low price.
In most medical offices, the need for positioning foam is minimal. To keep costs down, they opt for basic uncoated foam. However, some
settings require protection against liquid absorption and bodily fluids. In the rare event of a patient bleeding on a non-coated foam positioning aid used by a doctor in a small practice, the foam must be disposed of, and a new one ordered.
One thing to consider when using coated foam positioning aids is their tendency to attenuate in scans using low Kv (kilovoltage). The lower the kilovoltage, the higher the likelihood that the edges of the foam positioning aid will show. As you increase the Kv of the scan, the positioning aid becomes less and less visible. Radiology technologists are trained to find the perfect balance between maximizing the visibility of the intended area and minimizing the attenuation of the positioning aid.
Three Types of Foam Positioning Aids
The first category of x-ray positioning aids consists of coated foam positioners, which are standard foam pieces coated with a protective chemical surface. This outer coating serves a dual purpose - maintaining the foam's flexibility while creating a non-porous exterior that can be easily cleaned and reused. The innovative coating not only repels fluids but also ensures optimal positioning accuracy. However, it's important to keep in mind that this delicate chemical film may be susceptible to tearing under pressure or specific impacts, requiring careful handling during use. Technologists should also keep in mind that this coating can also cause the positioning aid to be more visible in the final image when using lower Kv. Despite this potential vulnerability, the benefits of coated foam positioners in terms of functionality and durability make them an essential tool in medical imaging procedures.
Moving on to the next type, vinyl-covered foam positioning aids are firm foam shapes encased in a durable, vinyl material, providing a cleanable, non-porous surface similar to that of a boat seat. Some manufacturers opt for hook & loop connections to secure the vinyl over the foam, although this method may not ensure complete sanitation like some bolster options.
Unlike their open-cell counterparts, closed cell foam positioners are a newer innovation in the market and are currently highly recommended for imaging purposes. Crafted from low-density, non-porous, and exceptionally durable foam similar to top-quality pool noodles, these foam positioners do not require any coating to maintain their non-porous and resilient properties.
What sets closed cell foam positioners apart is their 100% radiolucent nature, meaning they do not appear on X-ray images, no matter how low the Kv. Available in a charcoal grey hue, these radiolucent foam positioners remain artifact-free even with regular use, eliminating any concerns about obstructing the field of view during imaging procedures.
Common Questions Regarding X-Ray Positioning Aids
What is a closed cell foam positioning aid?
Crafted from a specialized foam with each cell fully enclosed within its walls, closed cell foam positioning aids are more rigid, lightweight, radiolucent, and non-porous than their open cell counterparts. Closed cell foam positioners are crafted using a cutting-edge manufacturing process that involves exposing a closed cell foam rubber compound to high-pressure gas, such as nitrogen. This innovative technique results in foam positioners that are not only highly resistant to fluids and oils but also incredibly durable and easy to clean.
The unique design of closed cell foam positioners sets them apart in the medical imaging field, offering unparalleled quality and reliability during imaging procedures. Their radiolucent properties ensure that they do not interfere with X-ray images, providing clear and accurate diagnostic results. Additionally, their non-porous nature makes them easy to maintain and sanitize, meeting the highest standards of hygiene in healthcare settings.
Healthcare professionals rely on closed cell foam positioners for their exceptional performance and longevity, making them an essential tool in patient positioning during radiology exams. With their advanced features and benefits, these foam positioners contribute to the success of imaging procedures while prioritizing patient comfort and safety.
What is a non-coated foam positioning aid?
Raw, open-cell foam positioners are essential tools in medical imaging, although lacking a protective coating that makes them prone to fluid absorption and challenging to clean. Available in both stealth and non-stealth variations, these positioning aids offer basic functionality without resistance to liquids. While non-coated foam positioning aids may lack the durability and easy maintenance of their
coated counterparts, they serve a crucial role in certain medical settings where cost-effectiveness is a priority, and fluid exposure is not a concern. These uncoated foam positioners are versatile and can be used in various imaging procedures, providing essential support for patient positioning without compromising the quality of diagnostic images. Despite their simplicity, non-coated foam positioners play a valuable role in ensuring accurate and efficient radiology exams, making them a staple in the diverse world of X-ray positioning aids.
What is a coated foam positioning aid?
The coated foam positioners are not just ordinary positioning aids; they are a sophisticated solution designed to meet the demanding requirements of medical imaging procedures. With a special chemical coating that repels fluids and enhances visibility under X-ray imaging, these positioners offer a level of functionality and durability that is unmatched in the industry. The innovative coating not only protects the foam core but also ensures easy cleaning and maintenance, making it a valuable asset for healthcare professionals performing a wide range of imaging procedures. Whether it's ensuring optimal patient positioning or maximizing the clarity of diagnostic images, these coated foam positioners play a crucial role in delivering accurate and reliable results in the field of medical imaging.
What is a vinyl-covered foam positioning aid?
Vinyl-covered foam positioning aids like the Domico Med-Device Endovaginal Wedge offer a practical and durable solution for patient positioning during medical imaging procedures. Encased in sturdy vinyl material, these foam shapes provide a cleanable, non-porous surface that ensures optimal hygiene and ease of maintenance. Unlike traditional foam positioners, the vinyl covering adds an extra layer of protection against fluid absorption, making them ideal for medical settings where cleanliness is paramount. However, like with coated foam positioning aids, these positioning aids may attenuate in low Kv scans. With their firm yet comfortable design, vinyl-covered foam positioning aids strike the perfect balance between patient comfort and radiolucency, enabling healthcare professionals to achieve accurate and clear diagnostic images while prioritizing patient safety and well-being.
