Figure 1: Multitom Rax (Siemens Healthcare) is a multifunctional X-ray machine facilitating X-rays, fluoroscopy and 3D tomography due to a robotic mechanic to which the X-ray tube and the detector are attached. Shown is the adjustment of a 3D tomography of the lumbar spine in the upright weightbearing position. Additionally, supine 3D tomography is feasible.
