Abstract

A plurality of diagnostic scanners (S₁, S₂, . . . , S_n) share access to a remote, communal processing center (CP) that performs reconstruction and post reconstruction processing for various modalities. Each of the diagnostic scanners submits a data set to the remote center electronically over the lines (T). An scheduling computer (22) assigns a priority to each of the received data sets and controls a plurality of parallel processors (26₁, 26₂, . . . , 26_n) accordingly. The reconstructed image representations are sent electronically back to the address that sent them, or another designated location, for display on a monitor (28₁, 28₂, . . . , 28_n, 28_cf, 28_r). Upgrades loaded into the remote center are immediately available for all users. Software modifications, hardware adjustments, training services, operations monitoring, and scanner operating services of individual scanners are provided from the remote center.

Claims

1. A diagnostic imaging system comprising:

a plurality of scanning apparatuses which each generate data sets representative of an examination of a subject disposed in an imaging region of the apparatus;

at least one communal processing center remote from the scanning apparatuses that processes the data sets into image representations of the subject;

an information transfer pathway which transports the data sets from the scanning apparatuses to the communal processing center and transports the image representations from the communal processing unit to a display console.

2. The diagnostic imaging system as set forth in claim 1, wherein the communal processing center includes:

a plurality of computers among which the data sets are divided for parallel processing.

3. The imaging system as set forth in claim 2, wherein the communal processing center includes:

a scheduling computer that assigns a processing priority to data sets and schedules.

4. The diagnostic imaging system as set forth in claim 1, wherein the communal processing center includes at least one supercomputer that processes the data sets.

5. The diagnostic imaging system as set forth in claim 1, wherein the information transfer pathway includes Internet and network connections.

6. The diagnostic imaging system as set forth in claim 1, wherein the information transfer pathway includes:

a two-way dedicated hard-line connection between the scanning apparatus and the communal processing center.

7. The diagnostic imaging system as set forth in claim 1, wherein the display console is associated with the scanning apparatus that generated the reconstructed data.

8. The diagnostic imaging system as set forth in claim 1, wherein the diagnostic scanning apparatuses each include:

a reconstruction processor for processing data sets into image representations.

9. The diagnostic imaging system as set forth in claim 1 wherein the communal processing center includes a diagnostic computer which analyzes at least one of:

the data sets,

the reconstructed image representations,

malfunction logs,

usage logs,

real-time scanning operations, and determines at least one of maintenance, repair, upgrade, reprogramming, and hardware modification procedures to be performed on each imaging apparatus.

10. The diagnostic imaging system as set forth in claim 1 wherein the communal processing center further includes:

a billing processor which receives an identification of the scanner requesting each reconstruction, a priority of the requested reconstruction, and a nature of the reconstruction, the billing computer accessing a rate table and generating a corresponding bill.

11. The diagnostic imaging system as set forth in claim 1 wherein the central processing center further includes an operator assistance computer which supplies at least one of imaging protocols, demonstrations, after hours control functions, software modifications, remote control, and demonstration services to individual scanning apparatus.

12. The diagnostic imaging system as set forth in claim 1, wherein the communication pathway provides a specialist at the remote center access to at least some functions of a selected one or more scanning apparatus for at least one of:

demonstrating functioning of the scanning apparatus;

monitoring functioning of the scanning apparatus;

operating the scanning apparatus to perform diagnostic scans on subjects in the scanning apparatus;

repairing the scanning apparatus; and

,

upgrading the scanning apparatus.

13. An image reconstruction system comprising:

a gantry for examining a subject and generating a data set corresponding thereto;

a computer means for controlling the gantry to implement a selected protocol for examining the subject and for reconstructing the data sets into an image representation using at least first selected reconstruction algorithms;

a communication means for transmitting the data sets to a remote processing location for reconstruction into an image representation using at least second reconstruction algorithms and for receiving the reconstructed image representations therefrom.

14. The image reconstruction system as set forth in claim 13, further including:

a second gantry for non-invasively examining an interior of a subject;
