Abstract: A system for imaging biopsy samples obtained from a patient includes: a radiation source; a radiation detector having a surface that defines a first imaging region, a second imaging region, and a third imaging region; and a collimator having a body defining an opening and selectively adjustable between a first imaging position and a second imaging position. The first imaging position allows radiation rays to pass from the radiation source, through the opening, and into the second imaging region while restricting the radiation rays from passing into the first imaging region when the radiation source is in a first scanning position. The second imaging position allows radiation rays to pass from the radiation source, through the opening, and into the third imaging region while restricting the radiation rays from passing into the first imaging region when the radiation source is in a second scanning position.

Abstract: In the present invention, an image review method and system for performing the method is provided that enriches the information displayed in the reference image or synthetic views and/or slabs reviewed by the physician with colored layers of information obtained from an image volume and merged with the reference image, slabs and/or synthetic views. The colored layer enhancement of the reference image, slabs and/or synthetic views highlights the colored areas of interest or features from the image volume in the slabs and/or synthetic views in a manner that prevents the features from becoming lost due to tissue superposition effects or other issues with the combination of the colored layers and reference image to form the displayed combined images.
