Abstract

A teleradiology system for sending the raw data from a complete patient study to a remote location for a radiologist to make a final diagnosis. The system consists of two segments, a sending segment and a receiving segment. The sending segment consists of a universal floppy disk reading unit capable of reading raw data from a radiological device, (e.g., CAT Scanner, Nuclear Medicine Imaging device, Magnetic Resonance Imaging device, and the like) a personal computer, and a high speed modem. The receiving segment consists of a high speed modem to receive the data from the sending segment, a personal computer to control the receiving and manipulation of the data, and a high resolution monitor to view the images. The segments communicate through the modems and over existing telephone systems. At the remote location, the radiologist has the raw data and the capability of utilizing true windowing functions and true density values.

Claims

1. A teleradiology system comprising:

means for collecting raw digital data from a radiological device at a first location;

means for transmitting the raw digital data, as collected, to a second location;

means for receiving the transmitted digital data at the second location;

means for processing the received digital data; and

means for converting the processed digital data into analog signal to view at least one display image.

2. The system of claim 1 wherein the collecting means is a personal computer.

3. The system of claim 1 wherein the transmitting means is a high speed modem.

4. The system of claim 3 wherein the collecting means is a personal computer.

5. The system of claim 1 wherein the receiving means is a high speed modem.

6. The system of claim 5 wherein the transmitting means is also on high speed modem.

7. The system of claim 6 wherein the collecting means is a personal computer.

8. The system of claim 1 wherein the processing means is a personal computer.

9. The system of claim 8 wherein the collecting means is a personal computer.

10. The system of claim 9 wherein the transmitting means is a high speed modem.

11. The system of claim 10 wherein the receiving means is a high speed modem.

12. The system of claim 11 wherein the converting means is a high resolution monitor.

13. The teleradiology system of claim 1 wherein the converting means is a high resolution monitor.
