Abstract

A system to determine the isocenter of a LINAC includes apparatus and processes to determine the axis of rotation for the collimator, the gantry and the patient couch. The system and apparatus enable the tracking of the translation-rotation of mechanical components attached to the LINAC to compute the axis of rotation of Gantry, Collimator and Table. Based on the data collected related to these axis's the LINAC isocenter is determined. The apparatus utilized in the system includes a single emitter module, a signal receiver module, a positioning module. The system also includes a isocenter target module and a gravity module to determine a gravity vector for the LINAC.

Claims12

Dependent claims

A LINAC Isocenter determination process comprising:

mounting a signal emitter module on a gantry;
mounting a signal receiver module in line with the signal emitter module on a positioning module mounted on a couch;
determining an axis rotation for the gantry by rotating the gantry with the signal receiver module receiving signals from the signal emitter module during the gantry rotation;
determining an axis of rotation for a collimator by rotating the collimator with the signal receiver module receiving signals from the signal emitter module during the collimator rotation;
determining an axis of rotation for the couch by rotating the couch with the signal receiver module receiving signals from the signal emitter module during the couch rotation;
and
determining the LINAC isocenter by processing the signals received for the axis of rotation for gantry, the collator, and the couch.
