Therapeutic Accuracy of Robotic Stereotactic Radiotherapy in All Patients.
RGT: left and right move horizontally, LET (+)/RIG (−); ANT: anterior and posterior move vertically, ANT (+)/POS (−); NIF: head and foot direction horizontal movement, NIF (+)/SUP (−); LFT: left and right rotation, R (+)/L (−); H-UP: head up and down, head-up(+)/head-down(−); CCW: clockwise and counterclockwise directions, CW (+)/CCW (−). High-precision treatment of the spinal tumor could be achieved by robotic stereotactic radiotherapy.
