The present disclosure relates to an insert system for performing positron emission tomography (PET) imaging. The insert system can be reversibly installed to an existing system, such that PET functionality can be introduced into the existing system without the need to significantly modify the existing system. The present disclosure also relates to a multi-modality imaging system capable for conducting both PET imaging and magnetic resonance imaging (MRI). The PET and MRI imaging can be performed simultaneously or sequentially, while the performance of neither imaging modality is compromised for the operation of the other imaging modality.

A method of operating a DR detector including sequentially capturing image frames in the detector that include at least one dark image. The dark image is stored and a statistical measure for a subset of pixels in a captured image frame is compared with the same statistical measure of a subset of pixels in the stored dark image to detect an x-ray beam impacting the detector. An x-ray beam-on condition is indicated if a sufficient difference in intensity between the pixel subsets is detected. At least one more image frame is captured in the detector after detecting the x-ray beam. The current captured image and the at least one more image frame are added and the dark image is subtracted to form the exposed radiographic image.

Systems and methods for interpreting high-energy interactions on a sample are described in this application. In particular, this application describes analysis systems and methods, comprising impinging radiation from a source on an analyte, detecting energy interactions resulting from the impinging radiation using a detector, adjusting a signal emitted from the radiation detector using a pre-processing method to emphasize specific features of that signal, using a machine learning module to interpret specific parts of the adjusted signal, producing a quantitative and/or qualitative model using the machine leaning module, and applying the quantitative and/or qualitative model to a separate energy interaction. The quantitative and qualitative models derived from this training can be applied to new detector inputs from the same or similar instruments. Other embodiments are described.
