Abstract

A Picture Archiving and Communications System (PACS) transmits medical image information from a server to a viewing workstation. The mode of transmission that the system uses depends on a performance metric of the network. If the network is fast and stable, the entire DICOM image file is transmitted. If the network is not fast and stable, one of several other modes is used to transmit the image information.

Claims

1. An imaging system, comprising:

a processor executing computer readable code to;

operate as a network characteristic measurement system for a network comprising a first viewing workstation, a second viewing workstation, a first server, and a second server, the network characteristic measurement system to estimate a value of at least one characteristic of the network corresponding to medical image information transfer from the first server to the first viewing workstation, the characteristic of the network comprising at least one of a network bandwidth value, a network bandwidth reliability, or an expected processing power at the viewing workstation; and

transmit medical image information from the first server to the first viewing workstation, the medical image information to be transmitted in a selected transmission mode selected by the network characteristic measurement system from a plurality of transmission modes, the plurality of transmission modes organized in a hierarchy of transmission modes, each of the transmission modes being associated with a different threshold value of the at least one characteristic of the network, the selected transmission mode selected by comparing the value of the characteristic of the network to each of the threshold values, wherein the plurality of transmission modes comprises a first transmission mode that utilizes a native file format, a second transmission mode that utilizes lossless compression, a third transmission mode that utilizes an uncompressed region of interest (ROI), a fourth transmission mode that utilizes wavelet lossless compression, and a fifth transmission mode that utilizes wavelet lossless compression of an ROI;

wherein when the first viewing workstation receives an input requesting the transfer of medical image information from the first server, the network characteristic measurement system requests the transmission of the medical image information from the first server across the network to the first viewing workstation in the selected transmission mode; and

wherein the first server compresses the medical image information in accordance with the selected transmission mode, and transmits the compressed medical image information across the network to the first viewing workstation.

2. The imaging system of claim 1, wherein the first server stores the medical image information in a Digital Imaging and Communications in Medicine (DICOM) format.

3. The imaging system of claim 1, wherein the first server stores the medical image information as raw pixel data.

4. The imaging system of claim 1, wherein the medical image information is streamed from the first server to the first viewing workstation across the network, and the selected transmission mode is a selected streaming mode.

5. The imaging system of claim 1, wherein the first viewing workstation comprises the network characteristic measurement system.

6. The imaging system of claim 1, wherein the first server comprises the network characteristic measurement system.

7. The imaging system of claim 1, wherein the network is a first network, and wherein the second server stores medical image information and transmits the medical image information in a selected transmission mode of a plurality of transmission modes to the first or second viewing workstation across a second network, and wherein the network characteristic measurement system estimates at a value of at least one characteristic of the second network and initiates a transfer of medical image information from the second server to the first or second viewing workstation.

8. The imaging system of claim 7, wherein the value of at least one characteristic of the first network is independent from the value of at least one characteristic of the second network.

9. A method of adaptive selection of image streaming mode in a picture archiving and communications system (PACS) on a communications network comprising a first viewing workstation, a second viewing workstation, a first server, and a second server, the method comprising:

storing image information on the first server in communication with the first viewing workstation associated with the PACS;

initiating a transfer of image information from the first server to the first viewing workstation;

determining, with a network characteristic measurement system associated with the PACS, a value of at least one network characteristic of the communications network corresponding to medical information transfer from the first server to the first viewing workstation, the network characteristic measurement system being connected to the communications network, and the at least one network characteristic comprising at least one of a network bandwidth value, a network bandwidth reliability, or an expected processing power at the viewing workstation;

establishing, with the network characteristic measurement system, a hierarchy of a plurality of transmission modes wherein each of the transmission modes in the hierarchy is associated with a different threshold value of the at least one network characteristic, wherein the plurality of transmission modes comprises a first transmission mode that utilizes a native file format, a second transmission mode that utilizes lossless compression, a third transmission mode that utilizes an uncompressed region of interest (ROI), a fourth transmission mode that utilizes wavelet lossless compression, and a fifth transmission mode that utilizes wavelet lossless compression of an ROI;

selecting, with the network characteristic measurement system, a selected transmission mode from the hierarchy of the plurality of transmission modes, the selected transmission mode selected by comparing the value of the network characteristic to each of the threshold values;

requesting, with the network characteristic measurement system, the transfer of the image information from the first server to the first viewing workstation in the selected transmission mode;

compressing the image information by the first server in accordance with the selected transmission mode; and

transmitting the compressed image information in the selected transmission mode from the first server to the first viewing workstation via the communications network.

10. The method of claim 9, wherein selecting a transmission mode further comprises selecting a region of interest (ROI) from the image information;

and

wherein requesting the transfer of the image information comprises requesting the transfer of the ROI from the first server to the first viewing workstation.

11. The method of claim 9, wherein the first or second viewing workstation comprises the network characteristic measurement system.

12. The method of claim 9, wherein the first or second server comprises the network characteristic measurement system.

13. The method of claim 9, wherein the PACS includes a plurality of servers communicatively coupled to the first or second viewing workstation via a plurality of communications networks, and wherein determining the value of the at least one network characteristic comprises determining the value of at least one network characteristic between the first or second viewing workstation and one of the servers of the plurality of servers, and the network characteristic measurement system requests the transfer of the image information in the selected transmission mode from the one of the servers of the plurality of servers to the first or second viewing workstation.
