Abstract:
Digital Breast Tomosynthesis allows for the acquisition of volumetric mammography images. The present invention allows for novel ways of viewing such images to detect microcalcifications and obstructions. In an embodiment a method for displaying volumetric images comprises computing a projection image using a viewing direction, displaying the projection image and then varying the projection image by varying the viewing direction. The viewing direction can be varied based on a periodic continuous mathematical function. A graphics processing unit can be used to compute the projection image and bricking can be used to accelerate the computation of the projection images.

Claim (Index 19):
A method comprising the steps of:\n providing a computer including a graphics processing unit and a first memory, where the computer: a) receiving a first 3-D volumetric image of a first body part measured at a first time of measurement; b) computing a first plurality of generated 2-D projection images of the first 3-D volumetric image using a plurality of viewing directions; c) comparing the plurality of generated 2-D projection images to identify a first viewing direction that identifies an obstruction; d) receiving a second 3-D volumetric image, where the second 3-D volumetric image is selected from the group consisting of:\n (i) a second 3-D volumetric image of the first body part measured before the first time of measurement; \n (ii) a second 3-D volumetric image of the first body part measured after the first time of measurement, \n (iii) a second 3-D volumetric image of a second body part measured at the first time of measurement, where the second body part is used to carry out a structural comparison of the first body part; \n (iv) a second 3-D volumetric image of a second body part measured before the first time of measurement, where the second body part is used to carry out a structural comparison of the first body part; and \n (v) a second 3-D volumetric image of a second body part measured after the first time of measurement, where the second body part is used to carry out a structural comparison of the first body part; and \n e) computing a second plurality of generated 2-D projection images from the second 3-D volumetric image using the plurality of viewing directions; f) sending the first plurality of generated 2-D projection images, the second plurality of generated 2-D projection images and viewing instructions to a remote display device which includes a graphics display unit, where the viewing instructions determine the orientation of the second plurality of generated 2-D projection images with respect to the first plurality of generated 2-D projection images; and g) displaying the first plurality of generated 2-D projection images and the second plurality of generated 2-D projection images on the graphics display unit.
