Model-based position correlation between breast images

Abstract

Nowadays, breast diagnosis is based on images of different projections and modalities, such that sensitivity and specificity of the diagnosis can be improved. However, this emburdens radiologists to find corresponding locations in these data sets, which is a time consuming task, especially since the resolution of the images increases and thus more and more data have to be considered in the diagnosis. Therefore, we aim at support radiologist by automatically synchronizing cursor positions between different views of the breast. Specifically, we present an automatic approach to compute the spatial correlation between MLO and CC mammogram or tomosynthesis projections of the breast. It is based on pre-computed finite element simulations of generic breast models, which are adapted to the patient-specific breast using a contour mapping approach. Our approach is designed to be fully automatic and efficient, such that it can be implemented directly into existing multimodal breast workstations. Additionally, it is extendable to support other breast modalities in future, too

Deformable mapping technique to correlate lesions in digital breast tomosynthesis and automated breast ultrasound images

“…A recent study has proposed FE based non-linear biomechanical models for correlating breast structures between two compressed states for cranio-caudal, CC, to medial lateral oblique, MLO, mammography views. 28 Several studies, have found favorable results in using FE modeling between MRI to x ray registration for CC and/or MLO mammograms. 23,24,26,29 A recent study has found favorable results in relating lesions in supine breast ultrasound to prone MRI.…”

“…Immobilization of the breast with compression plates and paddles adds an additional challenge when relating areas of the breast between modalities.
