摘要： An apparatus for measuring the nonuniform attenuation caused by a patient's body in scintillation cameras is disclosed. The apparatus comprises a gantry having an annular support, a radiation source mounted on the annular support for emitting a radiation which is incident on the patients body, a dedicated radiation detector mounted on the annular support in opposed relation to the radiation source for detecting the radiation transmitted through the patient's body and a mechanism for rotating the annular support around the patient's body. The annular support defines at the center a cylindrical space where the patient's body is located along the longitudinal axis of the cylindrical space. The radiation source and radiation detector are rotated by 180 degrees around the longitudinal direction of the patients body while the radiation source scans the patient in the transversal direction such that the radiation attenuation in all directions around the patient's body can be measured.

摘要： An image generation method in a scintillation camera relates to a scintillation camera having a collimator for collimating gamma rays, a scintillation crystal for generating a light scintillation upon receiving a gamma ray, an array of photomultiplier tubes for receiving the generated light scintillation and for generating electrical signals according to amount and position of light received, and a display comprising pixels for displaying an image corresponding to an interpretation of the electrical signals received by the photomultiplier tubes. The method for interpreting the electrical signals received from an array of photomultiplier tubes includes the steps of: receiving electrical signals from the array of photomultiplier tubes; applying a first algorithm to generate a first calculated event position; assigning the first calculated event position to a pixel; applying a second algorithm to generate a second calculated event position; assigning the second calculated event position to a pixel.

摘要： A method for calibrating photomultiplier tubes in a scintillation camera having a plurality of light sources includes the steps of: pulsing all light sources simultaneously; reading the output of each photomultiplier tube; comparing the output of each photomultiplier tube with an expected value; determining whether the output of each photomultiplier tube is within a first specified tolerance; and adjusting each photomultiplier tube if the output of the photomultiplier tube is not within the first specified tolerance.

摘要： A positioner for a scintillation camera detector head is designed for use with a detector head of the type having a center of gravity dependent upon the weight of a removable collimator plate and being supported between a pair of substantially parallel support arms such that the detector head is rotatable relative to the support arms about an axis of rotation passing through the support arms. The positioner includes a pair of rigid detector head links for aligning the center of gravity of the detector head relative to the support arms. Each detector head link includes an arm end rotatably attached to the adjacent support arm by way of an arm axle, and a head end rotatably attached to the detector head by way of a head axle. The positioner also includes a lock for selectively securing the relative positions of the detector head and the detector head links.
