摘要：
A method includes receiving, from a volumetric imager, a first image including a target of a patient. The method further includes receiving a second image including the target of the patient. The method further includes tracking, by a processing device, a position of the target using the first image and the second image by maintaining a fixed alignment between a treatment beam of a linear accelerator (LINAC) and a source and detector pair of the volumetric imager during operation of the LINAC.
