    摘要: A camera generates digital image signals representing an image of one or more natural or artificial fiducials on a patient positioned on treatment or diagnosis equipment. A processor applies multiple levels of filtering at multiple levels of resolution to repetitively determine successive fiducial positions. A warning signal is generated if movement exceeds certain limits but is still acceptable for treatment. Unacceptable displacement results in termination of the treatment beam. Tracking templates can be generated interactively from a display of the digital image signals or through automatic selection of an image having the median correlation to an initial template. A gating signal synchronized to patient breathing can be extracted from the digital image signals for controlling the radiation beam generator.

    摘要: A camera system has a neural network for calibration of image distortion. The neural network learns the conversion from image coordinates with distortion to image coordinates with substantially reduced distortion, whereby the neural network provides image coordinates having substantially reduced distortion. In a learning process of the neural network, a relatively simple camera model is used to provide an instruction signal to the neural network according to sample data provided from the real camera.

    摘要: A robotic manipulator includes a plurality of segments connected by joints between a fixed base and the distal end of the arm. At least one of the joints comprises a servomotor having a stator and a rotor one of which is attached to a segment positioned closer to the fixed base, the other component of the servomotor being attached to a driven segment positioned closer to the distal end of the arm. The said mechanical arm is directly driven by the servo motor without provision of any transmission mechanism.
