QUERY-SPECIFIC GENERATION AND RETRIEVAL OF MEDICAL VOLUME IMAGES

摘要

Methods and a system are disclosed for providing a mechanism for searching and extracting three-dimensional regions of interest in image archives. In at least one embodiment, a textual search query serves as input and is processed in order to provide a newly generated query-specific volume image, including computed sub-volumes covering the anatomical structure the query refers to. The query is input via a graphical search interface and the sub-volumes are outputted also via the graphical search interface.

主权项

1. An automatic image preprocessing method for generating sub-volumes of a plurality of three dimensional medical volumes for the purpose of semantic extraction of anatomical structures, comprising:
providing or acquiring and reconstructing a medical three dimensional image as volume, which may contain different anatomical structures or a part of an anatomical structure; automatically detecting landmarks in the volume; matching the detected landmarks with at least one atlas image to generate an indexed volume; splitting the indexed volume into indexed sub-volumes according to atlas image data; and storing the indexed sub-volumes in a database.
