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.

The invention relates to manufacturing a surgical guide to be placed in a patient's mouth. The patient's mouth is scanned to obtain surgical-region scan data at a region where an implant is to be located. The patient's mouth is also scanned in the opened position to acquire dental conditions opposite from the surgical region so as to obtain opposing-condition scan data. A virtual model is developed using the surgical-region scan data and the opposing-condition scan data. Using the virtual model, a surgical plan is developed that includes the location of the implant to be installed in the patient. A virtual surgical guide is also developed based on the surgical plan. The dimensions of instrumentation to be used with the surgical guide are checked to ensure they will fit within the mouth by use of the opposing-condition scan data. After checking, final surgical-guide manufacturing information is obtained for manufacturing the surgical guide.
