摘要： In an X-ray imaging system, an arrangement is provided for readily aligning the system detector with the X-ray beam field, i.e., the projection of the X-ray beam into the plane of the detector. The arrangement is adapted for correcting or compensating for distortion which results from X-ray beam angulation, wherein the beam is projected toward the detector plane at an angle of less than 90°. Initially, the system X-ray tube is positioned to project the X-ray beam at a given beam direction angle &phgr;. A beam width angle &ggr;1 is then computed, from the given angle &phgr; and from specified values of the source-to-image distance and the length of the projected beam field. Thereupon, an offset value is determined from &ggr;1, &phgr; and the source-to-image distance to locate the geometric center of the beam field, and the center of the detector is aligned therewith.

摘要： A method is provided for determining source-to-image distance (SID) setpoints in a digital imaging system. SID setpoints are determined during a setup and calibration procedure which includes generating radiation beams while varying certain system parameters, such as the radiation source position, and detecting and determining the size of the radiation beams that impact on the digital detector. SID values and a separation gain constant can then be determined based on the calculated sizes of the detected radiation beams and the feedback signals which are representative of the various system parameters that were varied (e.g., source position, etc.) during the setup and calibration procedure. The separation gain constant and the calculated, empirical SID values can then be used to position the radiation source at any user-selected SID based on position sensor feedback signals. The procedure also provides for a calibrated readout of the SID, which can be displayed to a user of the imaging system.

摘要： A method is provided for determining source-to-image distance (SID) setpoints in a digital radiographic imaging system. SID setpoints are determined during a setup and calibration procedure which includes generating x-ray beams while varying certain system parameters, such as the x-ray source position or the size of the collimator opening, and detecting and determining the size of the x-ray beams that impact on the digital detector. SID values and a separation gain constant can then be determined based on the calculated sizes of the detected x-ray beams and the feedback signals which are representative of the various system parameters that were varied (e.g., source position, collimator blade position, etc.) during the setup and calibration procedure. The separation gain constant and the calculated, empirical SID values can then be used to position the x-ray source at any user-selected SID based on position sensor feedback signals. The procedure also provides for a calibrated readout of the actual SID, which can be displayed to a user of the imaging system.

摘要： A method is provided for automatically determining a variable laterally centered setpoint for a digital radiographic imaging system that includes a radiation source and a digital detector. The variable laterally centered setpoint is determined during a setup procedure which involves providing a detector at a detector location, positioning the radiation source at a first source location, detecting a radiation field generated by the source while at the first source location, determining the lateral centerline of the detected radiation field, repositioning the source to a second source location that is laterally displaced from the first location, detecting a second radiation field, and determining the lateral centerline of the second radiation field. A lateral gain constant for the imaging system can then be determined based on the determined centerlines of the first and second radiation fields and feedback signals from position sensors that are representative of the first and second source locations. Based on the lateral gain constant and the source position feedback signal, the source can be laterally centered with respect to the lateral centerline of the detector.
