Fig. 3From: Evaluation of inter- and intra-fraction 6D motion for stereotactic body radiation therapy of spinal metastases: influence of treatment timeRelationship between intra-fraction 3D Vector (CBCT12 + 23) motion (mm) for Pos_Old (solid blue dots) and Pos_New (empty red dots) as a function of time (min) measured either between CBCTpTT start and CBCT12 start or between CBCT12 start and CBCT23 start. The linear fits are shown with their corresponding equationsBack to article page
