A system for the automatic generation of custom report viewing utilizes imaging data and computer-aided detection technology to identify cancerous tumors. A typical collection of data from a patent's scan may include hundreds of images and associated data. The custom report viewer allows one physician, such as a radiologist, to analyze the data and prepare a report. The generated report may contain images, computed measurements, classifications based on a standard (such as the ACR BI-RADS for Breast MR), and locations relative to landmarks. Different physicians, such as an oncologist or a surgeon, may have need of differing images and supporting data for their own purposes. Each physician may select, in advance, custom selection criteria that are stored in association with that physician. A report generator module uses the stored selection criteria and report filtering to extract the images and supporting data specified by the particular physician. The system allows a surgeon to alter the selection criteria and obtain further images if necessary and permits the generation of multiple selection criteria by one physician for different purposes, such as surgical planning, therapy reporting, and the like.

A marking device for defining the margins and orientation of radiography specimens includes a plurality of visually distinctive markers joined by a base that holds the markers until the markers are secured to a specimen. The base serves as a holder for the individual markers as the markers are secured to a specimen with sutures or staples, at which time the markers are disconnected from the base. One or more markers may be secured to a specimen as needed to define the orientation of the specimen. By securing markers to specific locations on a specimen, a surgeon can indicate to radiologists and pathologists the specimen's orientation in the body before removal, thus aiding in future study of the specimen. Since the markers are made either wholly or partially from radiopaque material, the markers are visible when radiographed.

The present invention provides for the use of computer-aided detection (CAD) system output displays for providing accurate representations of areas for subsequent exams. Since the CAD output, unlike the original medical imagery, is not used during the initial reading, the radiologist does not mark it until a final determination is reached regarding subsequent procedures. Additionally, since the CAD output contains versions of the original imagery, the regions indicated by the radiologist are shown in the context of the particular anatomical detail for a given patient. This detail assists the technologist, other physicians and patients in more efficiently and accurately locating the exact area for subsequent exams.

The business method known as QAISys (Quality Assessment and Improvement System) is a process that rates comprehensively and continually the quality of medical images as determined by the interpreting radiologist. The output of this system conveys feedback from the radiologist to the performing technologist and his / her supervisor. This feedback enables medical radiologists, technologists, and managers to bridge any communication gaps between themselves in respect to the quality and effectiveness of medical images. It permits management to assess and track image quality for an entire medical imaging department by modality, location, and / or shift, and for each individual technologist. The QAISys method reveals the nature of recurrent quality failures and highlights which exam types need to be improved. QAISys then indicates practical, cost-effective means of assessing and improving the overall medical images for future patients.

X-ray mammography has been the standard for breast cancer screening for three decades, but offers poor statistical reliability; it also requires a radiologist for interpretation, employs ionizing radiation, and is expensive. The combination of multiple independent tests, performed effectively at the same time and co-registered, can produce substantially more reliable detection performance than that of the individual tests. The multi-sensor approach offers greatly improved reliability for detection of early breast tumors, with few false positives, and also can be designed to support machine decision, thus enabling screening by general practitioners and clinicians; it avoids ionizing radiation, and can ultimately be relatively inexpensive.
