FILM TO DICOM CONVERSION
First Claim
Patent Images
1. A computer-implemented method comprising:
- performing a Hough Transform to detect straight lines within an image of a scanned radiology film, the image including a plurality of sub-images in a grid pattern;
statistically analyzing results of the Hough Transform based on length of detected straight lines to identify gridlines between sub-images;
separating sub-images based on gridlines; and
storing the separated sub-images.

Abstract
Embodiments digitize radiology films into DICOM format. Radiology films typically include an array of captured images laid out in a grid pattern. To comply with DICOM format, the scanned image of a radiology film is segmented into sub-images and text is extracted from the sub-images to generate DICOM metadata. The sub-images and extracted text metadata are then combined to generate a DICOM-compliant multi-image file.
