Exposure condition decision support system and method

摘要

A console of an X-ray imaging system functions as a query receiver and a retrieval section to support decision on an exposure condition. The query receiver receives a retrieval query such as an exposed body portion and an exposure direction. The retrieval section refers to an exposure date of image files having the same patient ID number, and calculates an exposure interval between a pair of prior and subsequent image files the exposure dates of which are the nearest to each other. The exposure interval is compared with a threshold value. If the exposure interval is less than the threshold value, neither image file is assigned as a model image file. If the exposure interval is the threshold value or more, the subsequent image file is assigned as the model image file. The retrieval section retrieves the image file matching the retrieval query out of the model image files.

主权项

1. An exposure condition decision support system comprising:
an image data storage unit for storing a plurality of image files, each of said image files including data of a radiographic image, supplementary information, and an exposure condition of said radiographic image stored in relation to each other; a query receiver for receiving an input of a retrieval query; a model image file extracting unit for extracting one or more of said image files having a model image of said radiographic image as model image files, exclusive of said image files having a failure image or a re-exposure image of said radiographic image, by reference to said supplementary information; and a retrieval section for retrieving at least one of said image files having said exposure condition matching said retrieval query out of said model image files.
