SUBSCRIBE TO OUR BLOGTop Consideration while selecting a Digital Mammography Machine!
Buying new medical equipment is more of an investment rather than just a purchase. There are a variety of options available in the market that can confuse you to choose the best option for your requirement if you have no prior experience on this subject. The same stands true for Digital Mammography Machine. You need to consider all the points that can make your purchase a worthy one.
Introduction
Digital Mammography or full-field digital mammography (FFDM) is a kind of mammography system that utilizes a special solid-state detector which converts the X-ray energy directly into a digital image. The process is fast, and the digital images can also be stored and retrieved easily. As per the requirement, brightness, contrast, darkness, and other parameters can be adjusted. It is an excellent example of the rapidly evolving technology that has enabled the doctors in the field to recognize various deadly ailments like breast cancer at an early stage.
So, to end your stress over what one should consider before buying Digital Mammography medical equipment, given below are some of the checkpoints to help you make the right choice for your practice.
Digital Mammography Machine Checkpoints
Best suited digital detector technology for your practice
With direct and indirect conversion detectors as the methods of capturing the image in digital Mammography, choose a technology that fits best for your requirements.
Indirect Conversion Digital Detectors
This work similar to Screen film and utilize an indirect method of imaging X-Rays. The light generated by the X-ray interaction within the scintillator spreads in every direction. It consequently degrades spatial resolution. Needle-type scintillators can help in guiding the light to a pixel, but a particular degree of light still will spread to neighboring pixels, making it a disadvantage of the same.
Direct Conversion Digital Detectors
These are technological advancements over indirect conversion detectors. They don’t showcase the issue of light scattering that is experienced in the indirect ones. Clear and precise images are received through this digital detector technology. From the highest quality, radiographic images, and recognition of deadly ailments like cancer can be attained to offer a positive diagnosis to the patient.
It comprises of a selenium converter that operates at a frame rate of 10 images per second. With an X-Ray sensitivity of nearly 290 electrons/absorbed x-ray with almost 100% absorption of x-rays at beam energy of 18 keV, and others are potential factors to consider the excellence of this kind of technology of Digital Mammography.
Size of detector
As per The Mammography Quality Standards Act (MQSA), a minimum of two screen-film cassette sizes – 18 x 24 cm and 24 x 30cm should be used in a mammography system. The bigger the detector size, better is the image quality. Many times, 18 x 24 cm is unable to capture images. From dense to large breasts, it’s hard to capture clear images at once. You would need to capture several pictures that can be time-consuming and stressful for the patient too. It also requires repositioning and multiple compressions to get the correct image for the proper and right diagnosis.
Thus, in that case, the 24cm x 30cm detector works well that offers an added advantage of the ability to crop the image to reduce data transfer, as well as the reduced need for display and storage space. With no additional material costs in this size of the detector as an advantage, one may find the issue of positioning smaller breasts while using a detector of larger size. For a solution, one can utilize small compression paddles in conjunction with the larger detector to get the ideal images.
Image Resolution
A Pre-owned Digital Mammography Machine must be able to produce images in which the person can see very small objects. It is necessary as micro-calcifications can be small as 100 to 200 microns. To avail that kind of resolution, digital detectors with smaller pixels are preferred. With the decreased pixel size of the digital detector, the quantity of data in the image also increases suddenly. It further increases the cost of data storage, display capabilities, and network bandwidth. With the enhanced list of information that you get, the price also surges.
Detector Storage and transportation
While availing of a Digital Mammography Machine for Sale, one should get make sure that the system is kept in a climate-controlled environment since the detectors are sensitive to sudden temperature changes.
Also, the detectors are really sensitive, so you should acknowledge yourself with the procedure of shipment or mode of transportation of the same. Ensure that utmost safety and precautions are taken to get safe and undamaged delivery.
These are just some points that you should consider as a priority. For a worthy and satisfying purchase, you can also consult experts in the field to make the right decision. Also, purchasing a Refurbished Digital Mammography Machine won’t burn a hole in your pocket and will fulfill your requirements at once.
