Abstract: A system for determining spinal implants includes a surgical table that moves a patient secured on the table into different positions in response to patient command, including a position of pain (POP) where the patient experiences the most pain from one or more affected levels of the spine, and a position of comfort (POC) where the patient has the least amount of pain. A scanner scans the patient on the table at least at the POP and the POC, and produces corresponding radiographic image data. Image processing apparatus coupled to the scanner quantifies changes in the relative position of adjacent vertebra at each affected level when the vertebra move from their configuration in the patient's POP, to their configuration in the patient's POC. The apparatus can then select an optimal implant device from among a number of devices whose characteristics are stored in a system database.
