Abstract

A computer aided detection (CAD) system for assigning CAD applications to digital images. The system comprises a case input system (CIS), image data repositories and an algorithm server. There is also provided a method for assigning CAD applications to digital images the method comprising the steps of selecting an acquisition model (AM) and selecting a CAD application using the selected AM.

Claims

1. A method for assigning a computer aided detection (CAD) application to a digital image the method comprising steps of:

a) selecting an acquisition model from a plurality of acquisition models based on one or more attributes of the digital image; and

b) selecting a CAD application from a plurality of CAD applications using the selected acquisition model.

2. A method as claimed in claim 1 wherein the step of selecting an acquisition model comprises steps of:

a) obtaining the attributes of the digital image; and

b) performing a search to identify the acquisition model that most closely matches the obtained attributes of the digital image.

3. A method as claimed in claim 2 wherein the attributes comprises any one or more of:

a modality of the image acquisition and a subject of the image.

4. A method as claimed in claim 3 wherein the modality of image acquisition comprises anyone or more of:

X-ray imaging, ultrasound imaging, magnetic resonance imaging (MRI), computer tomography (CT).

5. A method as claimed in claim 3 wherein the subject of the image comprises anyone or more of:

breast, chest, heart, head, lungs and bones.

6. A method as claimed in claim 1 wherein the step of selecting the CAD application comprises steps of:

a) obtaining information concerning the digital image in accordance with the selected acquisition model;

b) performing a search to identify the CAD application that most closely matches the obtained information.

7. A method as claimed in claim 6 wherein the information comprises case parameters.

8. A method as claimed in claim 7 wherein the case parameters comprise anyone or more of:

X-ray film acquisition voltage, ultrasound frequency, number of images and type of exam.

9. A method as claimed in claim 8 wherein the type of exam comprises any one or more of:

a screening exam and a diagnostic exam.

10. A method as claimed in claim 1 further comprising the step of associating a primary digital label, containing information identifying the selected acquisition model and/or CAD application, with the digital image.

11. A method as claimed in claim 10 further comprising the step of inserting the primary digital label in a CAD algorithm server input queue.

12. A method as claimed in claim 11 further comprising steps of:

a) reading the digital label in the CAD algorithm server input queue;

b) obtaining the selected CAD application; and

c) processing the digital image with the selected CAD algorithm to produce CAD results.

13. A method as claimed in claim 12 further comprising the step of associating a secondary digital label, containing information identifying the CAD results, with the digital image.

14. A method as claimed in claim 13 further comprising the step of inserting the secondary digital label in a CAD algorithm server output queue.

15. A system for assigning a computer aided detection (CAD) application to a digital image the system comprising a case input system for selecting an acquisition model from a plurality of acquisition models based on at least one attribute of the digital image and for selecting a CAD application from a plurality of CAD applications using the selected acquisition model.

16. A system as claimed in claim 15 wherein the case input system comprises:

a) a user interface for obtaining the at least one attribute of the digital image and for obtaining information concerning the digital image in accordance with the selected acquisition model; and

b) searching applications for performing searches to identify the acquisition model using the at least one attribute of the digital image and to identify the CAD application using at least the obtained information concerning the digital image.

17. A system as claimed in claim 15 further comprising an algorithm server for retrieving and applying the selected CAD algorithm to the digital image to produce CAD results.

18. A system as claimed in claim 17 further comprising a digital label identifier for associating a primary and a secondary digital label with the digital image.

19. A system as claimed in claim 18 further comprising a CAD algorithm server input queue and a CAD algorithm output queue for storing the primary and secondary digital labels respectively.

20. A system as claimed in claim 15 further comprising a repository for storing the digital image and the CAD results.

21. A system as claimed in claim 20 further comprising a CAD report generator to display CAD results.
