Embodiment Construction

[0034] In this specification, breasts are presented in a first image and a second image. In the first image, the breast has a first deformed state. For example, the first deformed state is the natural shape of the breast. In this case, the first image may be referred to as a first image. It should be noted, however, that the natural state of the breast may vary with, for example, the patient's orientation (eg prone or supine). The first deformed state may also be a state in which the breast is slightly compressed, eg because the breast is inside the MR coil barrel. In the second image, the breast has a second deformed state. In the second deformed state, the breast may be compressed. In this case, the second image may be referred to as a second image. Extrusion can be performed with one or two extrusion paddles, as is known in the art. Squeezing can significantly change the shape of the breast compared to the first deformed state. For example, in the second image, the b...

Abstract

A system for multi-modality breast imaging comprises a first shape model constructing sub-system (1) for constructing a first shape model of the breast as represented in a first image (9), in which the breast has its natural shape, a second shape model constructing sub-system (2) for constructing a second shape model of the breast as represented in a second image (10), in which the breast is compressed by using a compression paddle, and a deformation estimating sub-system (3) for estimating a volumetric deformation field (12) defining a mapping between the first image (9) and the second image (10) on the basis of the shape models and an elastic deformation model (11) of the breast, the deformation estimating sub-system (3) being arranged to estimate the volumetric deformation field (12) on the basis of a first tissue surface of the breast in the first image (9); and a second tissue surface of the breast in the second image (10).

Description

technical field [0001] The present invention relates to multimodal breast imaging. Background technique [0002] Different imaging modalities can be used in the diagnosis of suspected breast cancer patients. For example, breast magnetic resonance (MR) imaging is well established in diagnostic imaging. Meanwhile, digital breast tomosynthesis (DBT) is getting more and more attention. Although both modalities generate 3D images of the breast, the information contained in the data is at least partially complementary. For example, calcifications are predominantly seen in DBT, whereas dynamic contrast-enhanced MR can highlight bulky lesions by detecting increased signal intensity due to tumor vascularization. [0003] US 2003 / 0194050A1 discloses a multimodal imaging system combining an X-ray tomosynthesis subsystem and a nuclear medicine imaging subsystem. These two subsystems operate while the breast is being compressed by the device for compressing the patient's breast. In ...
