Abnormal regions in living tissue are detected by obtaining images from different views of the living tissue; performing single-image CAD of each image to determine suspected abnormal regions depicted in the image; and combining measurements of the suspected abnormal regions in each image to determine whether a suspected abnormal region is an abnormal region. The living tissue may be a human breast and the abnormal region may be a mass in the breast. Ipsilateral mammographic views of the breast, a craniocaudal view, and a mediolateral oblique view may be used. Features which are relatively invariant or behave predictably with respect to breast compression are extracted using the single-image CAD and then combined.

Multi-view computer-assisted diagnosis

A method and system for remote diagnosis of a radiograph includes remote locations connectable to diagnosis locations. At a remote location a radiographic image containing a part depicting tissue and a background part is obtained and digitized. The image can be considered to comprise a plurality of blocks. A block of the digitized radiographic image is segmented to obtain a part of the block which depicts mainly tissue. The part of the block is compressed and transmitted to a diagnosis location. This segmenting, compressing and transmitting of blocks is repeated until the entire part of the image which depicts tissue has been transmitted to the diagnosis location. For an image, the digitization, segmentation, compression and transmission can be performed in a pipelined fashion. optionally computer assisted diagnosis (CAD) can be performed on the digitized image. The diagnosis location receives the compressed segmented image and any CAD results; uncompressing the received image; combining the CAD results with the uncompressed image; and displays the uncompressed image and the CAD results.
