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.

A control apparatus, system, method and program that enable simultaneous measurement of counts of multiple energy ranges in an efficient configuration are provided. A control apparatus 200 for controlling an X-ray detector 100 and outputting a measurement result comprises a setting section 220 configured to set the energy range of X-rays to be detected for each unit region of the X-ray detector 100, a data management section 250 configured to acquire a count value of the set energy range for each unit region as measurement data by a result of the X-ray measurement, and an outputting section 270 configured to output the measurement data. Thus, counting of multiple energy ranges can simultaneously be measured.

The present technology is directed to barium-133 (“Ba-133”) based standards that simulate expected energy emissions of iodine-131 (“I-131”), and thus can be used to calibrate radioactivity measuring instruments (e.g., dose calibrators) used to measure the radioactivity of I-131 drug products. The Ba-133 standards can be manufactured in geometries typical of those used to administer I-131 drug products, including, for example, as a capsule, a syringe, a vial, etc.

The present disclosure relates to methods and systems for calibrating an X-ray apparatus. The X-ray apparatus may include an X-ray detector and a collimator. To calibrate the X-ray apparatus, the methods and systems may include moving the X-ray detector from a first position to a second position along a first axis of a coordinate system, wherein the first position is under a scanning table, and the second position is outside the scanning table; moving the collimator to align the collimator with the X-ray detector at the second position; determining one or more parameters; and determining a second value of the first encoder when the collimator is aligned with the X-ray detector at the first position based on the one or more parameters.
