摘要： A method and system for detecting ionizing radiation emitted by material located over an extended area are provided. The method and system include a radiation detector disposed within a detector space on a detection axis. An array of collimating louvers is positioned about the radiation detector and is movable between different polar positions or angles relative to the detection axis. A mechanism is provided for moving the array of collimating louvers between the different polar angles to collimate the ionizing radiation from different locations over the area. The detector produces electrical signals as a function of the polar positions of the array of collimating louvers.

摘要： A gamma camera is provided in which the study protocol can be modified after the study has commenced and while event data is being acquired. In such a camera, study parameters such as the duration of the study, the number of image frames acquired, or the count criterion required to produce an image may be changed dynamically as the study proceeds. Thus, a nuclear study which is seen to be leading to unsatisfactory or less than optimal results may be altered during acquisition to increase the likelihood that diagnostically useful results will be produced.

摘要： The invention relates to an X-ray detector which includes at least one conversion unit (1) for converting absorbed X-ray quanta into electric charge signals, at least one evaluation unit (10) for amplifying and further processing the charge signals, and at least one data processing unit (11) for the acquisition, further processing and output of data. The charge signals are first amplified by an input amplifier (2) in the evaluation unit (10) after which they are evaluated in parallel in a counting channel (5) as well as in an integrator channel (7). The charge signals are then counted in the counting channel and the overall charge is integrated in the integrator channel as a measure of the energy delivered in the conversion unit (1). Because of the parallel presentation of the counting results and the integration results, more weight can be attached thereto in their respective range of the quantum flow that is optimum from a measuring point of view, so that the dynamic range of the X-ray detector is enlarged. Furthermore, additional information, for example, the mean absorption energy of the X-ray quanta, can be determined from the combination of the signals.

摘要： A dose distribution-measuring method capable of grasping a three-dimensional form of an object to be measured or evaluating a three-dimensional dose distribution thereof. The method comprises providing a multiple-eye type radiation meter probe in which at least two directional radiation detectors are arranged so as to be spaced from each other and directed toward a point to be measured; and carrying out dose measurement by directing the radiation meter probe toward an object to be measured from different positions to thereby determine a three-dimensional dose distribution of the object to be measured. Each of the radiation detectors has a structure in which a periphery of the radiation detector main body, except for a detection surface thereof, is surrounded by a radiation shield to reduce the effect of radiation from other than the object to be measured and from Compton scattering.

摘要： A radiation detection method and apparatus for detection of radiation in a small, portable, relatively inexpensive device. A radiation sensitive memory device and a radiation hardened memory device receive digital data from a digital data generator such as a pseudo-random word generator. The radiation sensitive memory device outputs an exposed digital data stream which, while stored in the radiation sensitive memory device, is susceptible to radiation incident upon the radiation sensitive memory device. The radiation hardened memory device is much less sensitive to radiation than the radiation sensitive memory device such that the test digital data stream output by the radiation hardened memory device is much less effected by radiation than the exposed digital data stream. The exposed digital data stream and the test digital data stream are compared to determine whether the exposed digital data stream was exposed to radiation while stored in the radiation sensitive memory device. Differences between the exposed digital data stream and the test digital data stream are generally indicative of exposure to radiation. Errors detected between the exposed digital data stream and the test digital data stream are measured per unit time and can be converted to a radiation exposure measurement. One or more pre-set radiation exposure measurement thresholds establish conditions at which alarms are activated in the event that the radiation exposure measurement exceeds one of the thresholds. The radiation exposure measurement can also be displayed, such as on an LCD display.

摘要： This invention provides an EDS detector in which even if connecting pipes vibrate due to gas flow, such vibration will not be transferred to a cryostat side and in which a small-sized gas-circulation-type refrigerator is provided in the cryostat sliding in a given direction, helium gas is supplied through the connecting pipes to the refrigerator, and an x-ray detecting element is cooled by means of the refrigerator. In connecting pipes, a connecting pipe body portion is connected to a pressure-converting value unit which is fixedly held in a vibration-proofing stand. Additionally, weights can be selectively applied to a flexible connecting pipe to further dampen vibrations.
