Abstract

A user interface for facilitating the input of films into a computer-aided diagnosis system is disclosed. The user interface includes a scanner which receives and scans the film-based images, and a film feeder which holds and transports them to the scanner. A touch sensitive display screen is provided to display status information to and receive instructions from an operator. The display screen displays miniature images of the films having color-coded borders so that the operator monitors the processing of the films. The interface also includes a bar code reader and allow the operator to conduct procedures for testing the scanner.

14. The user interface of claim 12 wherein said status information comprises at least one display image, each of the at least one display images displaying features of one film-based medical image such that errors in loading can be detected by the user.

15. The user interface of claim 14 wherein said status information further comprises a color-coded border surrounding each of the at least one display images, the color-coded border indicating to the user the current processing status of the one film-based medical image.

16. The user interface of claim 1 wherein said user interface is in communication with a digital medical imaging system.

17. The user interface of claim 16 wherein the status information indicates to the user that the digital image data represents a medical image which does not correspond to a predetermined expected image, and wherein the input information comprises information indicating to the computer-aided diagnosis system to organize the digital image data so as to re-position the medical image.

18. The user interface of claim 1 wherein said user interface is in communication with a digital image storage system.

19. The user interface of claim 18 wherein the status information indicates to the user that the digital image data represents a medical image which does not correspond to a predetermined expected image, and wherein the input information comprises information indicating to the computer-aided diagnosis system to organize the digital image data so as to re-position the medical image.

20. A user interface for facilitating input of film-based medical images into a computer-aided diagnosis system for detecting anatomical abnormalities in the film-based medical images, the user interface comprising:
