Automated digitized film slicing and registration tool
View Patent ↗Film-based images can be scanned in a conventional manner, then digitally designated and “cut” from the digital file resulting from the scan. These selected images can then be collated and registered as individual images, or slices in certain contexts, allowing them to be assembled in various presentations, such as in stack mode with digitally-acquired images. The resulting collated files can then be stored by the user as a new series of images. The technique thus greatly facilitates the access and comparison of the images regardless of the originating medium.
1. A method for separating digitized images on a digitized sheet of film, comprising:
accessing a digitized sheet of film having a number of images acquired discretely from one another with an medical imaging modality, the digitized sheet of film resulting from scanning of an analog sheet of film of the images, wherein the images are arranged in a regular grid on the analog sheet of film;
configuring a digital template based on the number of images and on the regular grid; and
digitally slicing and collating the images on the digitized sheet by applying the digital template to the digitized sheet to provide collated digitized images corresponding to the number of images in the regular grid on the analog sheet of film.

16. The system of claim 15 , further comprising means for displaying the collated digitized images on a PACS workstation monitor in stack mode or cine mode.
17. The system of claim 15 , further comprising means for ordering and registering the collated digitized images.
18. The system of claim 15 , wherein each of the digitized images comprise borders defined by one or more of the number or the dimensions of each of the digitized images.
19. The system of claim 18 , wherein the means for configuring a digital template is based on the borders of the digitized images, and without performing image segmentation.
20. The system of claim 15 , wherein the means for configuring a digital template is based on the number and dimensions of the image frames, and not on the content of the digitized images.
21. The system of claim 15 , wherein the means for configuring a digital template is based on the number and dimensions of the image frames without interpreting content of the images.
