Spine SRS is involving a high dose of radiation to tumors of the spine and spinal cord aiming to spare normal surrounding tissues and avoid unwanted side effects. Given that challenge, it is required precise localization and accurate dose delivery to avoid critical dose deposition in the spinal cord. Spine phantom is an anthropomorphic 3D-printed phantom that simulates the anatomy of a real lumbar spine case with bone and soft tissue-equivalent materials. With dosimetry options within the vertebrae and the spinal cord is an ideal tool for End-to-End testing in spine radiosurgery treatments during commissioning and periodic QA.
The unique advantage of having realistic bone and soft-tissue contrast in both CT and MR imaging makes Spine an excellent tool for adaptation of advanced spine SRS technique.
