The talk covers the design and evaluation of a device adding 3-D ultrasound scanning to a digital mammography (breast x-ray) system. The presentation centers on the specific application and device, but also touches on more general topics such as stereo image calibration and experimental design for evaluating needle placement accuracy. Note: the video takes a few seconds to buffer and begin playing.


REGISTERED 3-D ULTRASOUND and DIGITAL STEREOTACTIC
MAMMOGRAPHY for BREAST BIOPSY GUIDANCE

Large core needle biopsy is a common procedure used to obtain tissue samples when cancer is suspected in diagnostic breast images. The procedure is typically performed under image guidance, most commonly using freehand ultrasound or stereotactic mammography (SM). To utilize the advantages of both imaging modalities, we developed a biopsy device combining three-dimensional ultrasound (3DUS) and digital SM imaging with computer-aided needle guidance. This talk will discuss the design of our system, current methods in digital stereo X-ray and 3-D ultrasound imaging and validation experiments using tissue-simulating phantoms. A paper outlining this work was recently published: “Registered 3-D Ultrasound and Digital Stereotactic Mammography for Breast Biopsy Guidance”, M. R. Irwin, D. B. Downey, L. Gardi, and A. Fenster. IEEE Transactions on Medical Imaging, vol. 27, no. 3, pp. 391-401, Mar. 2008.
