Abstract: A method and system for producing tomosynthetic images of a patient's breast. An x-ray source that delivers x-rays through a breast immobilized and compressed between a compression paddle and a breast platform and form an image at a digital x-ray receptor panel. Multiple x-ray images are taken as the x-ray source and the receptor move relative to the immobilized breast. In one preferred embodiment, the x-ray source travels from −15° to +15°. The source can travel in an arc around the breast while the receptor travels linearly while remaining parallel and at the same distance from the breast platform. The sets of x-ray image data taken at different angles are combined to form tomosynthetic images that can be viewed in different formats, alone or as an adjunct to conventional mammograms.

Abstract: Systems and methods for breast x-ray tomosynthesis that enhance spatial resolution in the direction in which the breast is flattened for examination. In addition to x-ray data acquisition of 2D projection tomosynthesis images ETp1 over a shorter source trajectory similar to known breast tomosynthesis, supplemental 2D images ETp2 are taken over a longer source trajectory and the two sets of projection images are processed into breast slice images ETr that exhibit enhanced spatial resolution, including in the thickness direction of the breast. Additional features include breast CT of an upright patient's flattened breast, multi-mode tomosynthesis, and shielding the patient from moving equipment.

Abstract translation: 一种用于生产患者乳房的合成图像的方法和系统。 x射线源，其通过在压缩桨和乳房平台之间固定和压缩的乳房提供x射线，并在数字X射线受体面板上形成图像。 多个x射线图像作为x射线源，受体相对于固定的乳房移动。 在一个优选实施例中，x射线源从-15°行进到+ 15°。 该源可以沿着乳房周围的弧线行进，同时受体在线性移动的同时保持与乳房平台相同的距离。 组合以不同角度拍摄的X射线图像数据组合以形成可以以不同格式单独或作为常规乳房X线照片附件的辅助视图观察的合成图像。
