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.

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.

An apparatus for detecting small field circular collimators when connected to a linear accelerator machine (LINAC). Each small field circular collimator is provided with some uniquely identifying trait depending upon its size. The adaptor of LINAC includes sensors to detect the uniquely identifying trait of the small field circular collimator. The information from the sensor about the small field circular collimator is conveyed to the LINAC to verify that the collimator is properly installed and the correct size collimator is being used.

The present invention is a device for the restraint of patients on a treatment table. More specifically, the invention is designed to provide lateral side pressure on a patient in the abdomen, thorax, and hip areas during a radiation treatment. The main components of the device are paddle(s) and at least one crossbar assembly. The paddles are coupled to a crossbar assembly, which is positioned on a treatment table under the body cushion in which the patient is positioned. The paddles can be moved laterally along the crossbar such that they put lateral pressure on the cushion and the patient.

Device for restraint of patients on a table

A rotatably adjustable patient support apparatus including a lower base assembly for mounting to a pedestal and an upper base assembly for mounting to a patient couch. The upper and lower base assemblies are connected by three spaced apart connectors, each of which includes two parts joined by a ball joint swivel bearing to enable pivoting of the connector parts about each of two horizontally disposed axes where the axes are perpendicular to one another. One of the connectors is stationary and the other two are mounted to move longitudinally along the base assemblies on guide rails. The guide rails of the upper base assembly are mounted to ramps such that predetermined movement of the two movable connectors cause the upper base assembly to pitch or roll, or to pitch and roll simultaneously. Movement of the two movable connectors is by acme screw and nut sets. A bearing and another acme screw and nut set are mounted to the upper base assembly and together with a pin and slot connector enable a patient couch mounted to the upper base assembly to rotate about a vertical axis independently or simultaneously with the upper base assembly pitching and rolling.
