World’s First Twin Robotic X-ray System Meets FDA Approval

World’s first Twin Robotic X-ray system has uses in radiography, fluoroscopy and angiography, with 3D imaging capabilities. 

(Nov. 29, 2015) – Siemens Healthcare has announced that the U.S. Food and Drug Administration (FDA) has cleared the Multitom Rax (Robotic Advanced X-ray), a universal diagnostic imaging system that enables a wide range of examinations in multiple clinical areas – from emergency medicine and interventional to pain management and orthopedics, and from conventional 2D radiography to fluoroscopy examinations and angiography applications – all in one room using one X-ray system. The world’s first Twin Robotic X-ray system, the Multitom Rax boasts a unique design that enables, for the first time, the acquisition of 3D natural weight-bearing images.¹

“With the Multitom Rax, Siemens is proud to introduce the world’s first Twin Robotic X-ray system,” says Martin Silverman, Vice President of X-ray Products at Siemens Healthcare North America. “This universal X-ray system delivers unprecedented versatility for healthcare facilities. Now, clinicians can perform a multitude of imaging exams in one room without moving the patient. With the Multitom Rax, we’re opening a new chapter in X-ray technology.”

Watch the above video to see how the Multitom Rax Twin Robotic X-ray system eliminates need for patient repositioning as well as patient transfer to other imaging locations for additional procedures. 

Robotic precision in X-ray
The unique open design of the Multitom Rax Twin Robotic X-ray system features a height-adjustable patient table and two independent, ceiling-mounted robotic arms for the X-ray tube head and the flat-panel detector for almost unlimited positioning freedom anywhere in the room. Both robotic arms can be moved into position automatically or manually with servo motor support to make fine adjustments. While one robotic arm moves the X-ray tube, the other arm carries the 17” x 17” flat panel detector, which can acquire static, dynamic, and Real 3D sequences. The operator is always in control of the system’s movement and able to position both robotic arms precisely and safely around the patient.

3D imaging helps enable diagnostic certainty
The Multitom Rax Twin Robotic X-ray system enables, for the first time, the acquisition of 3D images¹ under the patient’s natural weight-bearing condition – whether they are seated, lying down, or standing. Images acquired in the natural standing position are essential because the knees, pelvis and spinal column appear differently when the patient’s body weight is applied compared to when the patient is lying down. 

The Multitom Rax’s 3D-ready image capabilities¹ can offer better diagnostic and planning certainty than images that do not reflect a natural weight-bearing condition. Conventional 2D X-rays do not always reveal fine hairline fractures in the bone. In cases of a suspected bone fracture, the patient historically has required a computed tomography (CT) 3D image to confirm the diagnosis. With the Multitom Rax Twin Robotic X-ray system, a 3D image¹ can be acquired on the same system, so the patient does not have to wait for a future appointment or be transferred to a CT system. 

Built-in features like Comprehensive CARE (Combined Applications to Reduce Exposure) and more precise positioning of the system aid in reducing patient radiation dose. 

 ¹Currently 3D imaging on the Multitom Rax is only possible with 3D-capable post-processing software.
