Navigation among multiple breast ultrasound volumes
First Claim
1. A computer-implemented method for facilitating review of data associated with different volumetric ultrasonic scans of a same breast, the breast having been compressed in a generally chestward direction by a compressive surface for each of the different volumetric ultrasonic scans, the compressive surface encompassing a nipple of the breast, comprising:
- receiving, at one or more computer processing units, first and second data volumes derived respectively from the different volumetric ultrasound scans;
displaying a first image representative of values at a first plurality of known locations within said first data volume;
receiving, at the one or more computer processing units, a selection of a first location within the first data volume relative to said first displayed image;
operating the one or more processing units to identify a second location within the second data volume having a similar spatial disposition relative to the nipple and the compressive surface as said first location within said first volume, whereby said second location at least roughly corresponds to a same locality of tissue within the breast as said first location; and
displaying a second image representative of values at a second plurality of known locations within said second data volume including said second location, said second image comprising a visible mark denoting said second location thereon.

Abstract
Navigation among breast ultrasound volumes derived from different volumetric ultrasonic scans of a same breast is described. On a display of a breast ultrasound workstation, a first image derived from a first ultrasonic volume is displayed. A user selection of a source region of interest (ROI) in the first image is received. A destination ROI within a second ultrasonic volume is identified that at least roughly corresponds to a same locality of tissue in the breast as the source ROI. A second image derived from the second ultrasonic volume and including the destination ROI is displayed, the destination ROI being highlighted.

8. A computer-implemented method for facilitating review of data associated with different volumetric ultrasonic scans of a same breast, comprising:
-
receiving, at one or more computer processing units, first and second data volumes derived respectively from the different volumetric ultrasound scans;
displaying on a display device a first image representative of values at a first plurality of known locations within said first data volume;
receiving, at the one or more computer processing units, a selection of a first location within the first data volume relative to said first displayed image;
operating the one or more processing units to identify a second location within the second data volume at least roughly corresponding to a same locality of tissue within the breast as said first location; and
replacing said first image on said display device with a second image representative of values at a second plurality of known locations within said second data volume including said second location, said second image comprising a visible mark denoting said second location thereon. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for automated navigation of breast ultrasound information, comprising:
-
displaying a first image derived from a first ultrasonic volume of a breast acquired during a first volumetric scan thereof, said first image comprising one of (i) a thick-slice image representing said first ultrasonic volume within a slab-like subvolume thereof, and (ii) a planar image representing said first ultrasonic volume along a plane therethrough;
receiving a user selection of a source region of interest (ROI) in said first image;
mapping said source ROI from said first image into said first ultrasonic volume according to a known position of the slab-like subvolume or plane associated with the first image within the first ultrasonic volume;
mapping said source ROI within said first ultrasonic volume into a corresponding destination ROI within a second ultrasonic volume of the breast acquired during a second volumetric scan thereof taken at a different position or orientation relative to said first volumetric scan;
mapping said destination ROI within said second ultrasonic volume onto a second image, said second image comprising one of (i) a thick-slice image representing said second ultrasonic volume within a slab-like subvolume thereof, and (ii) a planar image representing said second ultrasonic volume along a plane therethrough, said mapping being in accordance with a known position of said slab-like subvolume or plane within the second ultrasonic volume;
displaying said second image to the viewer; and
highlighting said destination ROI on said second image. - View Dependent Claims (16, 17, 18, 19, 20)
