What You Need to Know About Digital Mammography Systems
Among the many types of used medical equipment available today, digital mammography systems are in greater demand than ever. The reason for this may be based on patient concerns about the higher radiation exposure that comes from older mammography equipment. Plus, these machines offer a higher degree of spatial resolution and they store images more efficiently than older models. According to the American Cancer Society, breast cancer rates are on the rise. In their most recent published study, it was estimated that 192,370 new cases of invasive breast cancer would be discovered in 2009, with more than 40,000 women expected to die from the disease in that year alone. Only lung cancer was responsible for a higher number of deaths among women.
Greater awareness of the need for early detection of breast cancer has led many patients to be their own advocates. Beyond the regular mammograms recommended by their gynecologists, women are seeking out digital mammography specifically. This is especially true among women with dense breasts or a family history of breast cancer who wants to be sure their test results are accurate. Buying used digital mammography equipment is usually the best option for women’s healthcare clinics and hospitals, but there are three different technologies in use today. Before looking at used medical equipment in this area, you should know if you want a direct or indirect x-ray conversion detector, or a slot scanning system.
Images created by digital mammography systems are usually displayed on two high resolution monitors within the examination area; with a third monitor displaying patient information. Digital mammography machines are known to have a deeper dynamic range than film and/or screen imaging medical equipment, but it is important to keep in mind that pixel size is not always a good indicator of high resolution with these systems. Blurring and noise within the detector system can have a negative impact on resolution. The type of digital imaging used in mammography utilizes pattern recognition software to highlight any suspicious findings in the image, thereby bringing a potential tumor to the attention of the doctor.
