Abstract
A method for determining image quality of a digital radiographic image. The method is executed at least in part by a computer system. The method obtains image data for the digital radiographic image, identifies one or more regions of interest in the digital radiographic image, derives an image quality score that indicates the image quality of the digital radiographic image by computing at least a contrast-to-noise value for image data content within the one or more regions of interest, and reports the derived image quality score for the image.
Claims21
A method for determining the image quality of a digital radiographic image for a patient, the method executed at least in part by a computer system and comprising:
- obtaining image data for the digital radiographic image;
- identifying two or more general anatomical regions of interest in the digital radiographic image;
- establishing a predetermined weighting factor for each of the two or more general anatomical regions of interest prior to obtaining said digital radiographic image;
- deriving an image quality score indicative of the quality of the digital radiographic image by integrating the weighting factors and the associated image quality score from each of the two or more general anatomical regions of interest;
- and
- reporting, displaying, storing, or transmitting the derived image quality score for the image.
A method for evaluating a digital radiographic image, executed at least in part by a computer system, comprising:
- obtaining the digital radiographic image for a patient;
- obtaining information about the condition of the patient;
- identifying two or more general anatomical regions of interest in the digital radiographic image according to the obtained information about the condition of the patient and forming a patient profile;
- establishing a predetermined weighting factor for each of the two or more general anatomical regions of interest prior to obtaining said digital radiographic image;
- computing an image quality score indicative of the quality of the digital radiographic image by integrating the weighting factors and the associated image quality score from each of the two or more general anatomical regions of interest according to the profile of the patient;
- and
- reporting, displaying, storing, or transmitting the derived score.
