Abstract

In one embodiment of the invention, there is an ultrasound processing system that communicates images over a single asynchronous serial channel according to a scheme that does not require an isochronous serial channel and that switches among ultrasound imaging modes robustly. For example, the system is configured to packetize ultrasound image data of at least one ultrasound imaging mode into a stream of data frames and to convey the stream of data frames via the asynchronous channel. Each data frame includes indication of the ultrasound imaging mode and includes ultrasound-imaging-mode-specific imaging parameters. Other embodiments exist.

Claims

1. A system for ultrasound medical imaging, the system comprising:

a first ultrasound information processing device configured to packetize ultrasound image data into a stream of data frames and to convey said stream of data frames and control parameters via a serial communication channel, wherein each of multiple data frames conveyed over a duration of said stream of data frames includes an indication of an ultrasound imaging mode and includes ultrasound-imaging-mode-specific imaging parameters within each of multiple data frames that are descriptive of structure of a data frame, wherein the structure of each data frame comprises a header and a body, the image data and control parameters arranged to remain in sync during scan mode changes, the image data stored in the body, the control parameter stored in the header; and

a second ultrasound information processing device configured to receive said stream of data frames and control parameters via said serial communication channel, and to recognize the ultrasound imaging mode of received image data from the indication.

2. A system according to claim 1, wherein said serial communication channel comprises an asynchronous channel, and said stream of data frames is communicated via said asynchronous channel.

3. A system according to claim 2, wherein said asynchronous channel is configured to include error control capability.

4. A system according to claim 1, wherein an isochronous serial communication channel is not required for communicating ultrasound image data from said first ultrasound information processing device to said second ultrasound information processing device.

5. A system according to claim 1, configured wherein said serial communication channel comprises a non-isochronous channel, and at least half of all ultrasound image data conveyed from said first ultrasound information processing device to said second ultrasound information processing device during a user session is communicated via said non-isochronous channel.

6. A system according to claim 1, wherein said first ultrasound information processing device is configured wherein said duration of said stream of data frames is one over which a human operator receiving the stream of data frames has not changed at least one ultrasound imaging mode.

7. A system according to claim 1, wherein said first ultrasound information processing device is configured, when brightness mode, hereinafter referred to as B-mode, is desired by the human operator, to produce a stream of data frames that each have a first header that indicates B-mode, a body that includes B-mode image data and B-mode parameters, and a frame tailer;

and

wherein said first ultrasound information processing device is configured, when brightness-and-color mode, hereinafter referred to as B+C-mode, is desired by the human operator, to produce a stream of data frames that each have a second header that indicates B-mode, a body that includes B-mode image data and B-mode parameters, a third header that indicates color mode, hereinafter referred to as C-mode, a body that includes C-mode image data and C-mode parameters, and a frame tailer.

8. A system according to claim 7, wherein said first ultrasound information processing device is configured, when brightness-and-doppler mode, hereinafter referred to as B+D-mode, is desired by the human operator, to produce a stream of data frames that each have a first header that indicates B-mode, a body that includes B-mode image data and B-mode parameters, a second header that indicates doppler mode, hereinafter referred to as D-mode, a body that includes D-mode image data and D-mode parameters, and a frame tailer.

9. A computer memory product, comprising:

at least one computer readable non-transitory storage medium;

first computer code stored on said at least one computer readable storage medium, the first computer code including instruction to at least a first computer processor to;

package ultrasound image data into a stream of data frames, each of multiple data frames over a duration of said stream of data frames including an indication of an ultrasound imaging mode, control parameters and ultrasound-imaging-mode-specific imaging parameters, the imaging parameters within said each of multiple data frames being descriptive of structure of a data frame within the said each of multiple data frames, wherein the structure of each data frame comprises a header and a body, the image data and control parameters arranged to remain in sync during scan mode changes, the image data stored in the body, the control parameter stored in the header; and

convey said stream of data frames via a serial communication channel; and

second computer code stored on said at least one computer readable storage medium, the second computer code including instruction to at least a second computer processor to;

receive said stream of data frames via said serial communication channel;

recognize the ultrasound imaging mode of received image data from the indications within a data frame and the structure of each received data frame; and

process the received image data, based on recognized mode and structure of each received data frame, to facilitate display of the received image data.

10. A computer memory product according to claim 9, wherein said instruction to convey comprises instruction to convey said stream of data frames via an asynchronous channel.

11. A computer memory product according to claim 10, wherein said instruction to convey does not require an isochronous serial communication channel.

12. A computer memory product according to claim 9, wherein said instruction to at least a first computer processor is configured for said instruction to package to be executed even over an instance of said duration of said stream of data frames over which desired ultrasound imaging mode remains unchanged by a human operator who is viewing displayable image data.
