Abstract

The invention concerns a method of carrying out a televisit which comprises the steps: acquiring the data of a patient, which are relevant for the televisit, recording an image of at least one body zone of the patient, which is relevant for the televisit, and transmitting the data and the image to a medical institution. The method according to the invention is distinguished in that a 3D-image is recorded as the image of the body zone of the patient, which is relevant for the televisit.

In addition there is provided a televisit apparatus (1; 100) for carrying out a televisit comprising an acquisition unit (5; 103) for acquiring data of a patient, a transmission unit (9) for sending the data, and a camera (7; 107) for recording an image of at least one body zone of the patient. The apparatus (1; 100) according to the invention is distinguished in that the camera (7; 107) is a 3D-camera.

a 3D-image is recorded as the image of the body zone of the patient, which is relevant for the televisit.

2. A method according to claim 1 characterised in that both personal and also medical data are acquired as relevant patient data.

3. A method according to claim 1 characterised in that the data are acquired as reactions to questions and/or instructions presented to the patient.

4. A method according to claim 3 characterised in that the questions and/or instructions are transmitted at the beginning of or during the televisit to a televisit device which is disposed at the location of the patient.

5. A method according to claim 3 characterised in that the questions and/or instructions are stored in a televisit device disposed at the location of the patient.

6. A method according to claim 1 characterised in that the transmitted data are stored in the medical institution.

7. A method according to claim 1 characterised in that the data and/or the questions or instructions are transmitted to the medical institution by telephone line.

8. A method according to claim 1 characterised in that the data and/or the questions or instructions are transmitted by cellular radio.

9. A method according to claim 1 characterised in that the data and/or the questions or instructions are transmitted by way of the Internet.

10. A method according to claim 1 characterised in that the data and/or the questions or instructions are transmitted in encrypted form.

11. A method according to claim 1 characterised in that for calling up the data in the medical institution an identification of the person performing the calling-up procedure is interrogated.

12. A method according to claim 1 characterised in that during recording of the 3D-image a pattern is projected onto the body zone of the patient, which is relevant for the televisit.

13. A method according to claim 12 characterised in that the 3D-image is recorded in a wavelength range other than the visible range.

14. A method according to claim 12 characterised in that the both a 2D-image or a 3D-image is recorded in the visible wavelength range and a 3D-image is recorded in a wavelength range other than the visible wavelength range.

15. A method according to claim 12 characterised in that the pattern is projected in the invisible wavelength range.

16. A method according to claim 1 characterised in that measurement of the body zone of the patient, which is relevant for the televisit, is effected on the basis of the 3D-image.

17. A method according to claim 1 characterised in that a plurality of 3D-recordings are put together to form a film.

18. A 3D-camera, in particular for use in carrying out a televisit, comprising an objective (210) and a camera chip (202), characterised in that the objective (210) includes two recording devices (212a, 212b) for recording partial images of an original (50) of which the image is to be produced, from two different recording directions, wherein a respective partial image is produced for each direction, and the objective (210) is such that both partial images are produced on the camera chip (202) in mutually juxtaposed relationship.

19. A 3D-camera according to claim 18 characterised in that the objective (210) has more than two recording devices (212a, 212b) for recording partial images of an original (50) of which the image is to be produced, from more than two different recording directions, wherein a respective partial image is produced for each direction, and the recording devices (212a, 212b) are so designed that all partial images are produced on the camera chip (202) in mutually juxtaposed relationship.
