Abstract: Examples of systems and methods for monitoring metabolic activity and detectors for detecting photons are disclosed. The methods can include detection in a front and a rear detector of a photon to determine a Compton cone. This Compton cone may be combined with further Compton cone, or Line of Response calculation to determine an origin of nuclear decay. In examples of the systems and methods, substantially real-time visualization of nuclear decay can be achieved.

Abstract: A method for photon counting for pixels in a pixelated detector is disclosed, wherein for each of the pixels, one or more neighbouring pixels are defined. The method comprises receiving a charge in one or more of the pixels and comparing for each of the pixels the charge with a trigger threshold. If the charge in a pixel is above the trigger threshold, the charge is registered in the pixel after a registration delay, wherein the registration delay is dependent on the level of the charge received in the pixel in such a way that a registration delay decreases with increasing charge. A counter for a pixel is incremented when the charge is registered and an increment of a counter of the neighbouring pixels is inhibited. Pixelated semiconductor detectors are also disclosed.

Abstract: The invention relates to a digital system (1) for performing stereotaxic biopsies with a biopsy needle. The inventive system (1) comprises a series of devices which are used to: emit X-rays, detect and transform X-ray photons into electric signáis, position a tissue sample between the X-ray source and the detector, process the electric signáis, and genérate images. The system can also be equipped with a series of devices complementary to those mentioned above, as well as a means for positioning the aforementioned devices in two positions and obtaining images in two different orientations.

Abstract: In the method are repeated the stages of: exposing (6) a zone of a sample to the X-rays through a collimator, exposing only the parts of the sample placed between it and some secondary boards of a main board; obtaining (7) the data generated by exposure of the sample; and moving (8) the mobile support to another zone of the sample. Next, the data to obtain a complete digital image are processed. The device comprises a source of X-rays, a data-gathering device, a detection module which has a main board upon which are arranged secondary boards, a collimator fitted between the main board and the source of X-rays; and a unit for processing the data. A continuous image without size limitation is obtained.
