Advantages of Tomosynthesis Over CT Scanning

Posted in on 23.08.11

Tomosynthesis is a technology that facilitates a lab technician to easily obtain an image of any chosen section from a single tomography scan. In a scan, the target area is irradiated with X-rays from various angles, and the captured images are reconstructed using a computer. The technician can generate as many images of each slice as necessary, in a single operation.

The theory of tomosynthesis was proposed before the widespread introduction of CT, and numerous attempts were made without success in acquiring clear images by conventional analogue tomography. With the widespread use of CT, analog tomography was becoming a technology of the past.

The development of the image intensifier, or X-ray imaging tube, saw a dramatic evolution of the X-ray detector, replacing the original photograph film technology. However, several challenges, including a narrower field of view and image distortion, remained unsolved until the introduction of flat-panel displays, which also allow dynamic imaging. However, due to the diffusion of light converted from X-rays, the widely used indirect-conversion type of flat-panel display were still unable to achieve satisfactory resolution.

Direct-conversion FPD technology has broadened the possibilities of image processing, and dramatically advanced the development of new applications, including tomosynthesis. Multiple slice images and an image of any chosen cross-section can be generated in just a few seconds by tomosynthesis. Active clinical applications are primarily in the orthopedics field, where tomosynthesis allows imaging to be performed while the patient is standing or bending the elbow or knee, or even wearing a cast. It also allows broken bones to be imaged when the patient has an artificial joint or other metal orthopedic implant. These are just some of the benefits of tomosynthesis that are not possible with CT.

When searching on MedWOW for tomosynthesis, go to MedWOW's all-inclusive and intuitive search engine, which allows you to find the exact tomosynthesis system that you are searching for, using filtering options such as: manufacturer, model, price range, year manufactured, location and many other filters. Used x-ray equipment on MedWOW even includes details which may have a significant impact on the medical facility's needs, such as: sizes in centimeters and inches. The tomosynthesis systems posted on MedWOW include various models from numerous manufacturers. For example, there is currently a wide range including: Shimadzu, GE Healthcare, Philips, Toshiba and others,  with even more being added all the time, so you are sure to find exactly the make and model exactly suited to your needs.

Another alternative is to post a buying request for your tomosynthesis equipment, by filling out a form and giving as much information as possible about the x-ray unit you need. MedWOW attracts sellers from all over the world and so you will likely be sent a few quotes for your selected tomosynthesis system.
