  • PATIENT POSITIONING FOR RADIOTHERAPY TREATMENT
    Publication number: 20230226377
    Abstract: Disclosed herein is a method of positioning a patient for radio-therapy treatment using a radiotherapy device. The method comprises determining an identity of a treatment beam that is to be used to treat the patient, determining an offset between a reference location and an isocentre location for the identified treatment beam that is to be used to treat the patient, and changing a spatial relationship between the patient and at least a part of the radiotherapy device, according to the determined offset.

  • Method and apparatus for laser wavelength stabilization
    Patent number: 6859469
    Abstract: In an apparatus and method for locking the wavelength of a laser, a fringe-producing optical element is disposed directly in the in the output beam from the laser. The fringe-producing optical element produces a fringe pattern in a second light beam derived from the output beam. The fringe pattern is detected by a detector unit. Signals generated by the detector unit are used to generate a laser tuning control signal that tunes the laser to a desired operating wavelength.
