Abstract: A multi-channel analog to digital conversion circuit and methods thereon are provided. The multi-channel analog to digital conversion cirucit comprises a plurality of linearized channels wherein each channel comprises a multi-stage pipelined charge-to-digital converter and an integrating capacitor within each stage of the multi-stage converter wherein analog residue is processed by subsequent analog to digital converter stages. Each stage of respective linearized channels is configured for calculating gain and offset for each stage in the channel and such gain and offset is used in subsequent integration periods.

Abstract: A method for viewing an abnormality in different kinds of images is described. The method includes scanning an object using a first imaging system to obtain at least a first image of the object, determining coordinates of a region of interest (ROI) visible on the first image, wherein the ROI includes the abnormality, and using the coordinates of the ROI to scan the object with a second imaging system.

Abstract: A method for generating an image of an object of interest includes acquiring a first three-dimensional dataset of the object at a first position using an X-ray source and a detector, acquiring a second three-dimensional dataset of the object at the first position using an ultrasound probe, and combining the first three-dimensional dataset and the second three-dimensional dataset to generate a three-dimensional image of the object.
