Abstract
In a method for radiographic scoring of a radiographic image at least one region of interest is determined. Each of the determined regions of interest is displayed in close proximity to a number of reference stages each having an associated score. For each region of interest a reference stage image best matching the displayed region of interest is selected and the score number associated with the selected reference stage image is associated with the region of interest. Score numbers retained for each of the regions of interest are combined to form the score number of the radiographic image.
Claims22
A method of radiographic scoring of a radiographic image comprising the steps of:
- acquiring a digital image representation of an image to be subjected to radiographic scoring,
- applying the acquired image representation to a display device and generating a displayed image,
- determining and extracting at least one region of interest on the displayed image,
- retrieving for each said at least one extracted region of interest a corresponding region of interest in reference stage images from a database, each said reference stage image having an associated score number,
- displaying the extracted regions of interest from the displayed image and the corresponding reference regions of interest from said reference stage images in juxtaposition on the same display screen,
- selecting a displayed optimal region of interest within said reference regions of interest which most optimally matches with the extracted region of interest from said displayed image,
- associating with the region of interest from the displayed image a score number corresponding with the selected region of interest from the reference stage images, and
- combining score numbers associated with said regions of interest into an overall score number pertaining to said radiographic image.
A computer readable medium encoded with a computer program adapted to carry out the following steps when run on a computer:
- displaying a radiographic image on a display device connected to said computer so as to generate a displayed image,
- upon indication by an operator of a region of interest in said displayed image, selecting and extracting said region of interest, and displaying said extracted region of interest on a display device,
- retrieving for a selected region of interest reference stage images from a database accessible via said computer, each of said reference stage images having an associated score number, displaying the retrieved reference stage images in juxtaposition with the said extracted region of interest on the same display device,
- selecting a displayed reference stage image which
- optimally matches with a displayed region of interest, associating with the displayed region of interest a score number which corresponds with the selected reference stage image,
- combining score numbers associated with said regions of interest into an overall score number pertaining to said radiographic image.
