Abstract

In a method and to an apparatus for evaluating a sequence of medical examination images successively presented at a viewing device using a data processing device operating on software having an evaluation algorithm for determining image regions exhibiting abnormalities, an acoustic signal is emitted by the dependent on the determination result, and/or the presentation time of an image on a monitor is influenced dependent thereon.

Claims

1. A method for evaluating a sequence of medical examination images comprising the steps of:

successively presenting medical examination images in a sequence at a viewing device;

controlling presentation of said medical examination images at said viewing device with a data processing device running on software, including control of a presentation duration at said viewing device of each of said medical examination images;

using said software in said data processing device, executing an evaluation algorithm for identifying if a medical examination image in said sequence exhibits an abnormality; and

upon identification of said abnormality, said software automatically lengthening said presentation duration of the medical examination image containing the abnormality.

2. A method as claimed in claim 1 wherein said viewing device is capable of emitting an acoustic signal, and comprising the additional step of, when no abnormality is identified, emitting no acoustic signal.

3. A method as claimed in claim 2 comprising emitting a high-pitched acoustic signal upon identification of said abnormality.

4. A method as claimed in claim 2 comprising emitting a loud acoustic signal upon identification of said abnormality.

5. A method as claimed in claim 2 wherein said evaluation algorithm identifies a medical examination image containing more than one abnormality, and comprising emitting an acoustic alarm signal upon identification of more than one abnormality in a medical examination image.

6. A method as claimed in claim 1 wherein said viewing device is capable of emitting an acoustic signal, and comprising continuously emitting a pleasant acoustic signal as long as no abnormality is identified.

7. A method as claimed in claim 6 comprising emitting a high-pitched acoustic signal upon identification of said abnormality.

8. A method as claimed in claim 6 comprising emitting a loud acoustic signal upon identification of said abnormality.

9. A method as claimed in claim 1 wherein said evaluation algorithm identifies a medical examination image containing more than one abnormality, and comprising stopping successive presentation of said sequence of medical images at said viewing device upon identification of more than one abnormality in a medical examination image so that the medical examination image wherein more than one abnormality was identified remains presented at said viewing device.

10. A method as claimed in claim 1 comprising, in said evaluation algorithm, allocating respective probabilities to abnormalities which are identified, comparing said abnormalities which are identified to a probability threshold, and optically presenting said abnormality on said viewing device if said probability threshold is exceeded.

11. A method as claimed in claim 1 comprising, in said evaluation algorithm, allocating respective probabilities to abnormalities which are identified, comparing said abnormalities which are identified to a probability threshold, and initiating said response only if said probability threshold is exceeded.

12. An apparatus for evaluating a sequence of medical examination images, comprising:

a viewing device at which medical examination images are successively present in a sequence;

a data processor, running on software, controlling presentation of said medical examination images at said viewing device, including controlling a presentation duration at said viewing device of each of said medical examination images;

said software in said data processor executing an evaluation algorithm for identifying if a medical examination image in said sequence exhibits an abnormality; and

upon identification of said abnormality, said data processor automatically lengthening said presentation duration of the medical examination image containing the abnormality.

13. An apparatus for evaluating a sequence of medical examination images as claimed in claim 12 comprising an acoustic emitter capable of emitting an acoustic signal, and wherein said data processor, as long as no abnormality is identified, causes no acoustic signal to be emitted.

14. An apparatus for evaluating a sequence of medical examination images as claimed in claim 13 wherein said data processor causes said signal emitter to emit a high-pitched acoustic signal upon identification of said abnormality.

15. An apparatus for evaluating a sequence of medical examination images as claimed in claim 13 wherein said data processor causes said signal emitter to emit to a loud acoustic signal upon identification of said abnormality.

16. An apparatus for evaluating a sequence of medical examination images as claimed in claim 12 comprising an acoustic emitter capable of emitting an acoustic signal, and wherein said data processor causes said signal emitter to continuously emit a pleasant acoustic signal as long as no abnormality is identified.

17. An apparatus for evaluating a sequence of medical examination images as claimed in claim 16 wherein said data processor causes said signal emitter to emit a high-pitched acoustic signal upon identification of said abnormality.

18. An apparatus for evaluating a sequence of medical examination images as claimed in claim 16 wherein said data processor causes said signal emitter to emit to a loud acoustic signal upon identification of said abnormality.

19. An apparatus for evaluating a sequence of medical examination images as claimed in claim 12 comprising an acoustic emitter capable of emitting an acoustic signal, and wherein said evaluation algorithm identifies medical examination image containing more than one abnormality, and wherein said data processor causes said signal emitter to emit an acoustic alarm signal upon identification of more than one abnormality in a medical examination image.

20. An apparatus for evaluating a sequence of medical examination images as claimed in claim 12 wherein said data processor stops successive presentation of said sequence of medical images at said viewing device upon identification of more than one abnormality in a medical image so that the medical examination image wherein more than one abnormality was identified remains presented at said viewing device.

21. An apparatus for evaluating a sequence of medical examination images as claimed in claim 12 wherein said evaluation algorithm allocates respective probabilities to abnormalities which are identified, compares said abnormalities which are identified to a probability threshold, and causes said data processor to optically present said abnormality on said viewing device if said probability threshold is exceeded.

22. An apparatus for evaluating a sequence of medical examination images as claimed in claim 12 wherein said evaluation algorithm allocates respective probabilities to abnormalities which are identified, compares said abnormalities which are identified to a probability threshold, and causes said data processor to initiate said response only if said probability threshold is exceeded.
