Breast imaging

Initial work-up for a woman presenting with a lesion or symptoms suggestive of breast cancer should include a careful history, physical examination of the breast, three-dimensional mammography, and possibly other breast imaging techniques such as ultrasound. Most (80% to 85%) breast cancers can be visualized on a mammogram as a mass, a cluster of calcifications, or a combination of both. Breast biopsy is indicated for...

An optical patient interface is shown right. The system can be used for brain and breast imaging. Applications are described in [222, 223, 224, 225,234, 444]. 

Quality assurance (QA) refers to all systematic activities undertaken by the breast imaging staff to ensure bigh-quality mammography (Hogge 1999).

Although CADe systems have been in use clinically for more than 10 years, there is still much needed research ongoing to improve the performance of the CADe schemes, to examine new uses of CADe, to establish CADx as a useful clinical tool, and application of CADe and CADx to new breast imaging modalities. These will be briefly discussed here.

Figure 7.4 shows a typical scanning pattern of a mammographer searching a breast image. Each dot represents a fixation or where the eye directs foveal vision. The lines represent saccades or the jumps that the eyes make between fixations and reflect the order in which the fixations were generated.
