Siemens Healthcare announced that FDA greenlit one of their latest developments – the first twin robotic X-Ray system.
Named Rax, or the Multitom Robotic Advanced X-Ray, it can be used for trauma, orthopedic, interventional and pain management applications. Being a twin X-Ray system, doctors can perfrom a host of different exams in one room without having to move their patients.
"The big benefit is that you buy one room and have multiple returns on investment," Pierre Niepel, director of product marketing for radiography and fluoroscopy X-ray products at Siemens, told HCB News.
Rax is the first system to allow for acquisition of 3-D natural weight-bearing images. It's important to take images while the patient is standing as the patient's knees, pelvis and spinal column show up differently in images when their body weight is applied contrary to they are lying down.
The system has robotic arms that are mounted into the ceiling: one controls the X-ray tube and the other controls the flat-panel detector — that can either be positioned automatically or manually with servo motor support to make precise adjustments. While one of the arms moves the X-ray tube, the other one moves the 17 inch by 17 inch flat-panel detector, which can records static, dynamic and real 3-D sequences.
Conventional 2-D X-ray systems do not show hairline fractures in the bone to full extent. Therefore, patients usually have to undergo a CT exam, because a 3-D image can confirm the diagnosis. Nevertheless, the Multitom Rax can acquire the 3-D image, so the patient does not have to be transferred to a CT system.
"It won't replace CT, but it will free up the CT scanner for patients with more complex cases who need CT the most," states Niepel.
