摘要： A method for routine monitoring and quality assurance of field asymmetry of high energy circular radiation beam producing equipment. The quality assurance process of field symmetry for devices such as stereotactic radiosurgery (SRS) systems is simplified by directly measuring the integration of the half-beam profile. The method of the invention provides that the field symmetry is obtained by positioning the tip of an ion chamber, with a collecting length approximately half the diameter of the beam, at the central axis of the beam, and rotating the ion chamber at varying angular positions, acquiring and comparing readings at desired angular positions. Each pair of readings from positions 180 degrees opposed from each other, are plugged into the equation, Asymmetry=2(R1−R2)/(R1+R2) to compute asymmetry.

摘要： A method for fiducial-less real-time motion tracking of abdominal tumors based on the correlation between the patient's breathing pattern and the diaphragm/lung border during treatment delivery. This invention utilizes an edge detection technique to delineate the diaphragm/lung border on radiographic images in order to calculate or determine tumor locations in the abdomen. The position of the diaphragm/lung border is synchronized with the breathing pattern obtained from continuous optical monitoring of a patient's respiratory cycle. The real-time optical breathing pattern obtained from monitoring is used to determine or calculate the position of the diaphragm/lung border during treatment delivery. The position of the diaphragm/lung border is then used to determine the tumor location in real-time. The target tumor coordinates generated through this process are used by the treatment delivery system to adjust the radiation beam geometry of the treatment delivery system to follow the tumor in real-time and accurately deliver radiation dose.

摘要： A method of automatically calibrating a motion detector and a motion detector adapted for calibration using the method. The method comprises setting the motion detector to a calibration mode, waiting a preset period of time for the installer to walk to the furthest distance, receiving a Doppler signal generated by motion at the furthest distance from the microwave motion detector within the protected area, measuring an amplitude of the Doppler signal and storing a motion detection threshold for the microwave motion detector. The motion detection threshold is a proportional to the measured amplitude.

摘要： The present invention is a security system and a method for reliably detecting an intruder without false alarms. The security system includes at least three motion detectors and processor circuitry adapted to collect a plurality of location samples and analyze them to determine if a target has transitioned from a first region to a second region, and when the target has transitioned from a first region to a second region, initiating a predetermined action. Each location sample is determined by: detecting motion from a target with each of the three motion detectors, determining the distance to the target for each of the three motion detectors, and triangulating the three determined distances to produce a two-dimensional location. The security system determines if a target has transitioned from a first region to a second protected region by comparing the plurality of location samples to perimeter location data stored in memory. Different modes of operation cause the security system to take different actions before and after the transition, such as generating an alarm or a warning signal. The security system may also include a display to show the location of one or more targets, which may be the intruder or the occupants of the premises.
