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 for installation as part of a data network in a computed tomography system, comprising:
a plurality of x-ray detectors, each of the plurality of x-ray detectors including a network-capable network interface; and
a switch or router, connected to each of the network-capable network interfaces of the plurality of x-ray detectors, each of the plurality of x-ray detectors including a distinct IP address such that the data network is adjustable to take a change in a number of the plurality of x-ray detectors into account,
wherein each of the plurality of x-ray detectors includes a time receiver configured to read out data from each of the plurality of x-ray detectors at a particular time and to transmit the data with a time stamp, the time receiver of one of the plurality of x-ray detectors within the detector apparatus being configured to be synchronized with other time receivers of the plurality of x-ray detectors within the detector apparatus.

2. The detector apparatus of claim 1 , wherein the network-capable network interfaces are 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 interfaces and the switch or router.

4. The detector apparatus of claim 1 , wherein an Internet protocol is used for communication between the network-capable network interfaces and the switch or router.

5. The detector apparatus of claim 1 , wherein the switch or router includes a plurality of switches or routers and wherein the detector apparatus includes the plurality of switches or routers, each of the plurality of switches or routers are connected to the network-capable network interface of at least one of the plurality of x-ray detectors.

6. The detector apparatus of claim 1 , further comprising:
a timer connected to the switch or router.

7. The detector apparatus of claim 6 , wherein the switch or router includes a plurality of switches or routers and wherein the timer is connected to the plurality of switches or routers.

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

9. The medical device of claim 8 , wherein the medical device is a computed tomography system.

10. The medical device of claim 8 , wherein the medical device includes a gantry with a stator and a rotor, and wherein the detector apparatus is included in the rotor.

11. The medical device of claim 8 , wherein the transfer unit comprises a slip ring transmission system.

12. The detector apparatus of claim 2 , wherein
the switch or router includes a plurality of switches or routers, and
the detector apparatus further comprises a timer connected to the plurality of switches or routers.

13. The detector apparatus of claim 1 , wherein the switch or router includes a plurality of switches or routers and wherein a timer is connected to the plurality of switches or routers.

14. A medical device having:
the detector apparatus of claim 2 ;
a transfer unit; and
an arithmetic unit.

15. The detector apparatus of claim 1 , wherein a same point in time is synchronizable to a clock of each of the time receivers to enable the data to be read out when a time coincides with the same point in time.

16. A method for operating a detector apparatus of a data network in a computed tomography system, the method comprising:
detecting x-ray radiation via a plurality of x-ray detectors, each of the plurality of x-ray detectors including a network-capable network interface, and acquiring data;
transferring the data acquired from the network-capable network interfaces of the plurality of x-ray detectors to a switch or router, via a network protocol, each of the plurality of x-ray detectors including a distinct IP address such that the data network is adjustable to take a change in a number of the plurality of x-ray detectors into account; and
synchronizing one of a plurality of time receivers on the detector apparatus with others of the plurality of time receivers on the detector apparatus, each of the plurality of x-ray detectors including one of the plurality of time receivers, to permit the transferring of the data acquired at a same point in time.

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

18. The method of claim 16 , wherein the synchronizing of the plurality of time receivers includes synchronizing clocks of the plurality of time receivers to enable the data to be read out when a time coincides with the same point in time.
