Abstract

A system and method is provided which allows for the transfer of an image data file such as a medical image data file. Device scan slices of an object are acquired per time point. A portion of the device scan slices of the object, e.g., live body organ, per time point which illustrate a change in the object from a previous time point is selected. At least one optical temporal image in spiral fashion per time interval is formed from the selected portion. The at least one optical temporal image is transmittable as an image data file to a location.

Claims

1. A computer implemented method for remote diagnosis of coronary artery disease, the method comprising:

imaging a heart of a patient of a hospital emergency department using a scanning multi-detector computed tomography device at an imaging location, the computed tomography device generating heart image data including three dimensional cardiac image data of a plurality of coronary arteries of the patient;

storing the image data in a server;

processing the image data with a computer to select a subset of the image data for transmission to a remote location, said processing including;

selecting motion free cardiac image data;

subsequently segmenting the motion free image data to select coronary artery image data from the stored image data to extract the selected coronary artery image data from the heart image data;

compressing the coronary artery extracted image data including lossless compression of the selected coronary artery image data to generate compressed coronary artery image data;

transmitting the compressed coronary artery image data to a remote location;

recording a remote diagnosis of the coronary arteries of the patient to store data indicating coronary artery disease of the patient;

storing the transmitted compressed coronary artery image data; and

wirelessly transmitting the remote diagnosis to a display device.

2. The method of claim 1, further comprising compressing the device scan slices from three dimensional data to at least one two-dimensional image.

3. The method of claim 1, wherein the method comprises transcoding the image data from motion-JPEG to H.264.

4. The method of claim 1, further comprising transmitting image data by video conference from the image data generated by the computed tomography device.

5. The method of claim 1, wherein the compressed image data is transmitted to a hand-held wireless device.

6. The method of claim 1, wherein the compressed image data comprises one scan slice from every ten scan slices acquired in succession.

7. The method of claim 1, further comprising:

extracting a specific coronary artery of interest from at least one motion free image for transmission as the image data file.

8. The method of claim 1, wherein the wireless transmission occurs via at least one of a wired network and a wireless network to an emergency department display.

9. The method of claim 1, further comprising:

imaging the heart at a heart rate of at least 65 beats per minute;

evaluating the transmitted image data file at the imaging location;

recording a diagnostic evaluation from the transmitted imaging data; and

transmitting the evaluation to at least one of a storage location and a use location.

10. The method of claim 9, wherein the storage location is at least one of a server, a plurality of servers, a storage device, a magnetic strip storage device, a chip storage device.

11. The method of claim 9, wherein an evaluation of the transmitted image data is effected by at least one of an urgent care clinic, a large cardiology practice group, a primary care practice group, a hospital, a university, and a location remote from where the image data was acquired.

12. The method of claim 9, wherein the image data file is compressed further for faster transfer of data via at least one of the Internet and a video conference system.

13. A computed tomography system for the remote evaluation of cardiac medical imaging data, comprising:

a computed tomography (CT) imaging device for imaging a patient of a hospital emergency department, the CT imaging device generating cardiac image data of a heart of the patient;

a processor connected to the CT imaging device, the processor being configured to select a portion of the cardiac image data which illustrate change in the heart from a previous time, the processor being operative to compress the cardiac image data by forming a compressed image data file from the selected portion of the cardiac image data and segmenting the compressed cardiac image data to extract at least one coronary artery image data file from the cardiac image data; and

a wireless network connected to the processor wherein at least one coronary artery image data file is transmitted to a remote location for diagnosis of coronary artery disease wherein a diagnosis is transmitted by wireless transmission to an emergency department display device.

14. The system of claim 13, wherein the extracted coronary artery image data file is transmitted to the remote location for at least one of storage and review.

15. The system of claim 13, wherein the CT imaging device includes at least one multi-detector scanning computed tomography imaging system connected to a server, the CT imaging device operable to generate 3000 or more cardiac images during a scan.

16. The system of claim 13, wherein the compression device includes a transcoder for transcoding the stored image data from motion-JPEG to H.264.

17. The system of claim 13, wherein the compressed image data is generated from every ten scan slices acquired in succession.

18. The system of claim 13, wherein at least one of the processor and a separate processor extracts a specific area of interest from each of the at least one coronary artery image data file for transmission as the image data file.

19. A method of imaging a heart of a patient to diagnose coronary artery disease, the method comprising:

imaging a heart of a patient with a scanning multi-detector computed tomography device connected to a hospital server;

generating an image data file of the heart that includes three dimensional coronary artery image data of the heart;

processing the image data file to reduce file size and thereby generate a reduced data image file that includes a-segmented image data of at least one coronary artery that has been extracted from the image data file of the heart;

sending the reduced data image file including the extracted image data of the at least one coronary artery to a remote location with the hospital server;

electronically storing a coronary artery disease diagnosis associated with the reduced data image file of the at least one coronary artery; and

transmitting the stored diagnosis and the reduced data image file of the at least one coronary artery by wireless communication to a wireless display device.
