Abstract

The present invention relates to medical imaging, and in particular a medical imaging detector. In order to improve and facilitate the collection of information, e.g. for medical diagnosis, a medical imaging detector is provided that comprises a first sensor arrangement ( 12 ) and a second sensor arrangement ( 14 ). The first sensor arrangement is configured to provide a first type of image data belonging to a first imaging modality. The second sensor arrangement is configured to provide a second type of image data belonging to a second imaging modality. The first imaging modality is an X-ray imaging modality, while the second imaging modality is a non-X-ray imaging modality. The first sensor arrangement comprises one or a plurality of first sensor segments ( 16 ) arranged within a first circumferential line ( 18 ) defining a first imaging area ( 20 ). The second sensor arrangement comprises one or a plurality of second sensor segments ( 22 ) arranged within a second circumferential line ( 24 ) defining a second imaging area ( 26 ). The first imaging area and the second imaging area at least partly overlap.

First claim

1 . A medical imaging detector, comprising:
a first sensor arrangement; and a second sensor arrangement; at least one substrate structure; wherein the first sensor arrangement is configured to provide a first type of image data belonging to a first imaging modality; wherein the second sensor arrangement is configured to provide a second type of image data belonging to a second imaging modality; wherein the first imaging modality is an X-ray imaging modality, while the second imaging modality includes ultrasound, optical, infra-red, ultraviolet, hyper-spectral, terahertz, or acoustic imaging; wherein the first sensor arrangement comprises one or a plurality of first sensor segments arranged within a first circumferential line defining a first imaging area; wherein the second sensor arrangement comprises one or a plurality of second sensor segments arranged within a second circumferential line defining a second imaging area; and wherein the first imaging area and the second imaging area at least partly overlap; and wherein the one or the plurality of first sensor segments and the one or the plurality of second sensor segments are integrated on the at least one substrate structure.

2 . Detector according to claim 1 , wherein the second sensor segment is a light sensor provided as at least one of the group of:
a visible light sensor; an ultraviolet light sensor; an infrared light sensor; and a hyper-spectral sensor.

3 . Detector according to claim 1 , wherein the second sensor segment is an acoustic sensor provided as at least one of the group of:
an audible sound sensor; an ultrasound sensor; and an infrasound sensor.

4 . Detector according to claim 1 , wherein the second sensor segment is a radiation sensor provided as at least one of the group of:
a terahertz radiation sensor; and a gigahertz radiation sensor.

5 . Detector according to claim 1 , further comprising:
a third sensor arrangement; wherein the third sensor arrangement comprises one or a plurality of third sensor segments arranged on the at least one substrate structure; wherein the third sensor segment(s) is (are) a non-imaging sensor(s) provided as at least one of the group of: a telemetry transceivers; a body area network transceiver; an electric field sensor; a magnetic field sensor; an attitude sensor; an acceleration sensor; a motion sensor; and a rotation sensor.

6 . Detector according to claim 5 , wherein the second sensor arrangement is arranged on the outer periphery of the first imaging area.

7 . Detector according to claim 6 , wherein the first sensor segments and the second sensor segments are interleaved in a common imaging area.

8 . Detector according to claim 7 , wherein, in a dual-imaging area, at least a part of the first sensor segments and the second sensor segments are arranged overlapping to provide dual imaging information for a common imaging area.

9 . Detector according to claim 1 wherein the first sensor arrangement and the second sensor arrangement are arranged on opposite sides of the at least one substrate structure.

10 . A medical imaging system, comprising:
a medical imaging detector according to one of the proceeding claims; and a first imaging source; wherein the first imaging source is an X-ray source configured to provide X-ray radiation as a first type of radiation to be detected by the first sensor arrangement of the medical imaging detector.

11 . System according to claim 10 , further comprising:
a second imaging source; wherein the second imaging source is configured to provide a signal to be detected by the second sensor arrangement of the medical imaging detector; and wherein the second imaging source is provided as at least one of the group of: a light source; an acoustic source; and a radiation source.

12 . A medical imaging method, comprising the following steps:
a) performing a first imaging modality examination and a second imaging modality examination on an object; and b) obtaining first image data of the first imaging modality and the second image data of the second imaging modality with a medical imaging detector; wherein the first imaging modality is an X-ray imaging modality, while the second imaging modality includes ultrasound, optical, infra-red, ultraviolet, hyper-spectral, terahertz, or acoustic imaging; and wherein the first image data is acquired in a first imaging area and the second image data is acquired in a second imaging area; wherein the first imaging area and the second imaging area at least partly overlap; and wherein the one the plurality of first sensor segments and the one or the plurality of second sensor segments are integrated on at least one substrate structure.

13 . Computer program element for controlling an apparatus which, when being executed by a processing unit, is adapted to perform the method steps of claim 12 .

14 . Computer readable medium having stored the program element of claim 13 .
