Method and apparatus for associating patient an exposure related data with a radiation image

Abstract

PROBLEM TO BE SOLVED: To provide a method and a system for associating data such as identification data of a patient and / or data related to an X-ray irradiation with a radiographic image.SOLUTION: Patient identification data and / or irradiation related data or a code uniquely identifying at least one of these data is transferred shortly before or during irradiation to a radio-frequency tag or the like coupled to a radiation detector. Transfer may be executed through a means of a reader / writer coupled to a radiation source.

Description

technical field [0001] The present invention relates to radiography, computed radiography and digital radiography. [0002] More precisely, the present invention relates to methods and systems for associating data, such as patient identification data and / or data related to X-ray exposure, with radiation images. Background technique [0003] In addition to conventional radiographic systems that record radiographic images of a patient on radiographic hard copy film, nowadays, computed radiography systems based on memory fluorescence technology are commonly used. [0004] In such computed radiography systems, an x-ray film cassette carrying a photo-stimulable phosphor screen is exposed to a radiation image of the patient's body. [0005] Various image-related data, e.g., demographic data (patient name, gender, birthday, etc.) and exposure-related data (e.g., mAs, kV, etc.) Information systems can be retrieved. [0006] These data are then transferred to an identification dev...

AI Technical Summary

Problems solved by technology

[0010] Clearly, the process described can lead to labeling errors due to different data associated with exposed x-ray film cassettes containing different images, and outside images cannot be identified

[0011] Data associated with x-ray film cassettes may also correspond to expected conditions, for example, the desired or default settings of the x-ray source, but due to various possible conditions, such settings may not accurately represent the effectively applied radiation data

[0012] Information and complaints studies have shown that radiology departments use systems based on the identification process of X-ray film cassettes, and that each step of the workflow is complex and error-prone

[0013] Another problem is that there is no feedback to the operator as to whether the x-ray film cassettes intended for exposures are strictly wiped before performing new exposures so that no image information exists
