摘要： An imaging system comprises a plurality of imaging detectors for acquiring imaging data. The plurality of imaging detectors is configurable to be arranged proximate to an anatomy of interest within a patient. Each of the plurality of imaging detectors has a field of view (FOV) and at least a portion of the plurality of imaging detectors image the anatomy of interest within the respective FOV. A processor receives the imaging data and processes the imaging data to form a multi-dimensional dataset having at least three dimensions.

摘要： A method for testing a stack of multiple battery cells, each comprising an anode, a cathode, and a separator as types of battery cell layers, wherein the separator is arranged between the anode and the cathode. In a first test step, it is checked whether the edges of the battery cell layers are within a first tolerance range, wherein the battery cells to which this applies are determined to be usable battery cells. Several of the usable battery cells are stacked to the battery cell stack. The battery cell stack is irradiated by X-rays. Via the X-rays, positions of those edges of a type of battery cell layers are determined which delimit at least two of the corners of these battery cell layers, checking whether the greatest distance between the equally located edges of each of the battery cell layers of the selected type is within a second tolerance range.

摘要： For dead time determination for a gamma camera or other detector, a long-lived point source of emissions is positioned so that the gamma camera detects the emissions from the source while also being used to detect emissions from the patient. The long-lived point source, in the scan time, acts as a fixed frequency source of emissions, allowing for dead time correction measurements that include the crystal detector effects.

摘要： A compression plate of a mammography apparatus has an upper surface which is irradiated with radiation, a lower surface which is opposite to the upper surface and comes into contact with the breast, and a surface which is parallel to the upper surface between the upper surface and the lower surface. In the compression plate, a compression plate scale for identifying an in-plane position of each surface is given to any one of the surfaces. A first display control unit of a console performs control to display a radiographic image captured by the mammography apparatus on a display unit. A second display control unit of the console performs control to display an image scale which indicates a position on the radiographic image corresponding to the in-plane position of the compression plate on the radiographic image displayed on the display unit.

摘要： Described is a directional gamma detector including a detection probe and a handgrip, wherein the detection probe includes: a supporting rod and a detection head coupled or integrated with a first end of the supporting rod. The detection head includes a plurality of detection elements distinct from each other for simultaneously detecting gamma rays directed in different directions and including at least one scintillation crystal and a corresponding first electronic conversion circuitry. Each detection element is associated with a respective collimator. The handgrip is equipped internally with a second electronic circuitry for converting the signals. The detection probe, and in particular a second end of the supporting rod, is reversibly connectable to the handgrip by a mechanical connector equipped with electrical contacts for transferring the signals from the first electronic conversion circuitry to the second electronic conversion circuitry.

摘要： An instrument and software methodology to detect a radioactive source and incorporates the following:
1) two radiation detectors in a co-axial configuration, housed in a handheld probe, and
2) a gamma detection control unit executing software algorithms to limit the functional field of view to the front aspect of the probe, vary the depth and width of the field of view to provide collimation without the use of metallic shielding, and allowing the instrument to measure the distance to the radiation source.-
