METHOD AND DEVICE TO EXAMINE A TISSUE SAMPLE

摘要

In a method and an apparatus to exam a tissue sample, a female breast is compressed in an x-ray imaging apparatus and a biopsy procedure is conducted to extract a tissue sample from the compressed breast, with the extraction taking place using images generated by the x-ray imaging system. While the breast is still compressed, the extracted tissue sample is transported to a region outside of the extraction location that is irradiated by x-rays from the x-ray source of the imaging apparatus, and is irradiated at that region by the x-ray source in order to generate 3D data from a radiation detector that are used to reconstruct a data set of slice images from common projections of the extraction region and the tissue sample. The reconstructed slice images are then displayed.

1. A method to examine a tissue sample, comprising:
compressing an examination subject between a compression plate and a radiation detector in an x-ray imaging apparatus comprising an x-ray source that emits x-ray radiation; conducting a biopsy of the compressed examination subject to extract a tissue sample from an extraction location within the examination subject, using x-ray images generated with said x-ray imaging system; while the examination subject is still compressed, transporting the tissue sample to a region outside of said extraction location that is within said field of view of said x-ray source; while said examination subject is still compressed, acquiring a 3D data set of said tissue sample and said region outside of said extraction location by moving said x-ray source through a plurality of positions and irradiating said tissue sample and said region from each of those positions to generate a plurality of common projections of the region and the tissue sample; reconstructing slice images from said common projections while said examination subject is still compressed; and displaying the reconstructed slice images at a display screen while said examination subject is still compressed.
