A distributed data collection architecture for a PET system includes a plurality of data collection boards, wherein each data collection board is coupled to a respective gantry segment of the PET system. The PET system includes a modular gantry having a plurality of gantry segments that are physically separate from each other, and each gantry segment includes a plurality of detector modules coupled to a respective data collection board. Each respective data collection board is configured to acquire all detector event data from a respective plurality of detector modules of the respective gantry segment the respective data collection board is coupled to. Only one data collection board of the plurality of data collection boards is configured to act as a master data collection board that collects all of the detector event data from each data collection board and to generate coincidence pairs from all of the detector event data.

Distributed data collection for large field of view positron emission tomography

A digital X-ray detector is provided. The digital X-ray detector includes control circuitry. The control circuitry is configured to obtain an electromagnetic interference (EMI) frequency of an EMI signal, to receive a signal to start a scan, to ensure EMI noise is in a same phase during acquisition of offset images and read images to enable a subtraction of the EMI noise, and to start the scan.

System and method for mitigating electromagnetic interference when acquiring image data

Various methods and systems are provided for x-ray imaging. In one embodiment, a method for an x-ray imaging system comprises acquiring, with an x-ray detector, an image including a noise artifact caused by electromagnetic interference, inputting the image to a trained neural network model to obtain a corrected image with the noise artifact removed, and outputting the corrected image. In this way, row-correlated noise artifacts caused by electromagnetic interference at the x-ray detector are eliminated or cancelled in real time and image quality is improved.
