  • DIRECT-DRIVE SYSTEM FOR GANTRY ROTATION
    Publication number: 20260069891
    Abstract: A radiation treatment system includes a base stand fixed to or resting on a support surface external to the radiation treatment system, a rotatable gantry with a treatment-delivering radiation source mounted thereon, wherein the rotatable gantry is rotatably coupled to the base stand via a bearing, and an electric motor for rotating the rotatable gantry and a portion of the bearing fixed to the gantry. The electric motor includes a first assembly that is fixed to the base stand; and a second assembly that is fixed to the gantry and is separated from the first assembly by an air gap, wherein magnetic flux across the air gap causes the electric motor to rotate the rotatable gantry and the portion of the bearing fixed to the rotatable gantry.

  • Radiotherapy system with linear motor for transverse actuation of base and rotation of gantry
    Patent number: 11266856
    Abstract: A radiation therapy system includes a treatment couch positioning assembly that is directly coupled to a fixed structure supporting the linear accelerator of the radiation therapy system. The radiation therapy system can be installed in a radiation therapy facility without the floor of the facility being excavated and a sub-floor structure, such as a base frame, being installed. To laterally position a patient relative to the linear accelerator, the treatment couch positioning assembly of the radiation therapy system is laterally translated via a linear motor, and laterally translates with the treatment couch, rather than cantilevering the treatment couch to either side of the couch positioning assembly.

  • System and methods for processing images to measure collimator leaf and collimator performance
    Patent number: 10702710
    Abstract: Systems and methods are proposed for accurate and efficient automatic measurement of jaw and leaf positioning in multi-leaf collimator imaging systems. Specifically, the method enables the automated and objective processing of images to determine characteristics of collimator jaws and MLC leaves. These novel techniques enable verification of collimator component positioning to ensure accurate beam modulation for radiation application procedures.
