Breast tomosynthesis with flexible compression paddle
First Claim
1. A mammography imaging system, comprising:
- an X-ray source;
an X-ray detector spaced apart from the X-ray source; and
an image data acquisition system for acquiring mammography image data; and
compression assembly positioned between the X-ray source and the X-ray detector, the compression assembly including a movable flexible compression paddle and a support plate spaced apart from each other and configured to hold an object to be imaged therebetween, and wherein the movable flexible compression paddle is formed of a flexible film material or flexible mesh material held by a frame, and wherein the flexible film or flexible mesh material conforms to the shape and size of the object to be imaged.

Abstract
A method of breast image reconstruction includes positioning a breast on an imaging system support plate, compressing the breast with a flexible paddle, obtaining imaging data, estimating a breast thickness profile by at least one of placing markers on the breast, performing an image-based analysis of the obtained data, using an auxiliary system, and performing a model-based computation. The three-dimensional (3D) reconstruction including using a thickness profile of the breast surface in at least one of an iterative reconstruction, a filtered back-projection reconstruction, and a joint reconstruction performed using information obtained from an ultrasound scan. A non-transitory medium having executable instructions to cause a processor to perform the method is also disclosed.
