Abstract: A system to determine the isocenter of a LINAC includes apparatus and processes. One embodiment does this by determining the axis of rotation for the collimator, the gantry, and may include the couch. In another embodiment only determining the axis of the rotation of the collimator is required. 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 couch. Based on the data collected related to these axes the LINAC isocenter is determined. The primary apparatus utilized in the system includes a single emitter module, a signal receiver module, and a positioning module. The system also includes an isocenter target module and a gravity module to determine a gravity vector relative to the signal receiver.

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.

Abstract: A breast treatment device including components to allow the positioning of a patient for medical treatment and ensuring the proper positioning of the patient's other breast to avoid its inadvertent treatment. A breast support is used to grip and securely hold the non-treatment breast in position on a sternal bridge which is easily positioned as warranted for a particular patient. The sternal bridge is positioned by moving support arms. The device includes cushions/supports for the patient's head, sternum, forearm, elbow, upper arm and hand.
