Abstract

A detector apparatus includes at least one x-ray detector, including a network-capable network unit; and a switching unit connected to the network unit of the x-ray detector.

First claim

What is claimed is:

1 . A detector apparatus, comprising:
at least one x-ray detector including a network-capable network unit; and a switching unit, connected to the network unit of the x-ray detector.

2 . The detector apparatus of claim 1 , wherein the network-capable network unit is embodied to transfer data via an Internet protocol.

3 . The detector apparatus of claim 2 , wherein a network protocol is used for communication between the network-capable network unit and the switching unit.

4 . The detector apparatus of claim 1 , wherein an Internet protocol is used for communication between the network-capable network unit and the switching unit.

5 . The detector apparatus of claim 1 , wherein the at least one x-ray detector includes a plurality of x-ray detectors, each including a network-capable network unit, and wherein the switching unit is connected to the plurality of network-capable network units of the plurality of x-ray detectors.

6 . The detector apparatus of claim 1 , wherein the switching unit includes a plurality of switching units and wherein the detector apparatus includes the plurality of switching units.

7 . The detector apparatus of claim 1 , wherein the at least one x-ray detector includes a time receiver, designed to read out data at a point in time and to transmit the data with a time stamp.

8 . The detector apparatus of claim 7 , further comprising:
a timer, connected to the at least one switching unit, wherein the timer is connected to the time receiver.

9 . The detector apparatus of claim 8 , wherein the switching unit includes a plurality of switching units and wherein the timer is connected to the plurality of switching units.

10 . A medical device having:
the detector apparatus of claim 1 ; a transfer unit; and an arithmetic unit.

11 . The medical device of claim 10 , wherein the medical device is a computed tomography system.

12 . The medical device of claim 10 , wherein the medical device includes a gantry with a stator and a rotor, and wherein the detector apparatus is included in the rotor.

13 . The medical device of claim 10 , wherein the transfer unit comprises a slip ring transmission system.

14 . A method for operating a detector apparatus, the method comprising:
a. detecting x-ray radiation via an x-ray detector, including a network-capable network unit, and acquiring data; and b. transferring the acquired data from the network unit to a switching unit, via a network protocol.

15 . The method of claim 14 , further comprising:
synchronizing a plurality of time receivers.

16 . The method of claim 15 , wherein the data is detected at a point in time.

17 . The method of claim 16 , wherein the data has a time stamp.

18 . The detector apparatus of claim 5 , wherein the at least one x-ray detector includes a time receiver, designed to read out data at a point in time and to transmit the data with a time stamp.

19 . The detector apparatus of claim 6 , wherein the at least one x-ray detector includes a time receiver, designed to read out data at a point in time and to transmit the data with a time stamp.

20 . The detector apparatus of claim 19 , further comprising:
a timer, connected to the at least one switching unit, wherein the timer is connected to the time receiver.

21 . The detector apparatus of claim 1 , wherein the switching unit includes a plurality of switching units and wherein a timer is connected to the plurality of switching units.

22 . A medical device having:
the detector apparatus of claim 5 ; a transfer unit; and an arithmetic unit.
