BREAST TOMOSYNTHESIS WITH FLEXIBLE COMPRESSION PADDLE
First Claim
1. A method of breast image reconstruction, the method comprising:
- positioning a breast on a support plate of an imaging system;
compressing the breast with a flexible paddle;
obtaining imaging data of the breast;
estimating a breast thickness profile by at least one of placing markers on the breast, performing an image-based analysis of the obtained imaging data, using an auxiliary system, and performing a model-based computation; and
performing a three-dimensional (3D) reconstruction of the breast, the reconstruction including mitigation of effects associated with compression by the flexible compression paddle.

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.
