Abstract

A programmable memory is provided in each of a plurality of detector modules arrayed in a positron emission tomography (PET) scanner. Each detector module memory stores data associated with its respective detector module. Each memory may be coupled to a processor via a transmission bus. A display device may be coupled to the processor for displaying information relating to information obtained from the detector module memories.

Claims

1. A method comprising:

installing a plurality of detector modules in a positron emission tomography (PET) scanner;

storing information associated with each of the plurality of detector modules in its respective detector module; and

accessing the stored information

wherein the step of accessing further comprises;

displaying a graphic representation of the array of the plurality of detector modules;

receiving stored information from the detector modules in response to the query; and

displaying a result obtained from the received stored information.

2. The method of claim 1, wherein the step of accessing comprises querying the plurality of detector modules.

3. The method of claim 2, wherein the step of querying comprises sending an information request from a remote location.

4. The method of claim 2, wherein the step of installing comprises positioning the plurality of detector modules in a set array, and the stored information comprises the respective location of each detector module in the array.

5. The method of claim 1, wherein the step of accessing further comprises:

selecting a detector module of interest from the displayed graphic representation, and the displayed result comprises information related to the selected detector module.

6. The method of claim 1, wherein the step of storing comprises:

defining a common set of information attributes associated with the plurality of detector modules.

7. The method of claim 6, wherein the step of accessing further comprises:

selecting a criterion for one attribute of the set of attributes; and

receiving information identifying all detector modules that meet the selected criterion;

wherein the displayed result comprises a graphical indication of the identified detector modules on the displayed array representation.

8. The method of claim 7, wherein the set of attributes comprises detector module identifier.

9. The method of claim 7, wherein the set of attributes comprises detector module model identifier.

10. The method of claim 7, wherein the set of attributes comprises detector module manufacturing date.

11. The method of claim 7, wherein the step of installing comprises testing the plurality of detector modules, and the set of attributes comprises detector module test date.

12. A system comprising:

a plurality of detector modules arrayed in a positron emission tomography (PET) scanner, each detector module comprising crystal scintillators and photodetectors and a programmable memory;

a processor coupled via a bus to the programmable memory of each detector module; and

a display device coupled to the processor;

wherein each detector module memory is configured to store data information associated with its respective detector module,

wherein the detector modules are arrayed in a plurality of rings, and the stored data comprises information relating to the respective location of each detector module in the array,

wherein the display device is responsive to the data processor to display a graphic representation of the array of the plurality of detector modules, and

wherein the memory is configured to store data in accordance with a common set of information attributes for the plurality of detector modules, and the processor is responsive to selection by a user of a criterion for one of the attributes to access the memory to retrieve data identifying all detector modules that meet the selected criterion.

13. The system of claim 12, wherein the processor is configured to enable or disable features, algorithms, or processes of the scanner based upon a model number, serial number, or other information stored in the detectors installed on the system.

14. The system of claim 12, wherein the processor is responsive to selection by a user of a detector module of interest from the displayed graphic representation to retrieve information with respect to the selected detector module for display at the display device.

15. The system of claim 12, wherein the display device is responsive to the processor to graphically indicate the identified detector modules on the displayed array representation.

16. The system of claim 12, wherein the processor is coupled to a network accessible by a remote service computer, whereby the remote service computer can access information stored in the detector module memories.

17. The system of claim 16, wherein the processor is responsive to a query transmitted by the remote service computer to access the detector module memories and transmit accessed data for display at the remote service computer.
