Abstract
A video stream of live medical images is generated at a local site having a medical image scanner. A live video stream is transmitted to at least one remote site via a network, which may include wired or wireless Internet connections. Network conditions are monitored during a network session and predictions are made on a predicted bit rate for transmission. The compression parameters for the live video stream are selected based on the predicted bit rate.
Claims30
A method of sharing medical information that includes streaming of ultrasound imaging data, comprising:
- receiving, at a computing device, a live ultrasound video stream generated by an ultrasound medical imaging scanner at a first medical site;
- monitoring, at the computing device, a set of quality of service metrics for a network communication session between the first medical site and a second medical site;
- predicting, based on the set of quality of service metrics, a minimum expected bit rate to transmit a live video stream from the first medical site to the second medical site that includes a compressed version of the live ultrasound video stream;
- selecting, in response to the minimum expected bit rate, video compression parameters to compress the live ultrasound video stream selected to maintain a live video stream based on the minimum expected bit rate;
- compressing, at the computing device the live ultrasound video stream according to the selected video compression parameters;
- and
- transmitting the compressed live ultrasound video stream from the first medical site to the second medical site.
A method of tuning video compression parameters for a live video stream of medical images in a networked telemedicine environment having variable network quality, comprising:
- receiving, at a computing device, feedback on network conditions for a network session between a first medical site having an ultrasound medical imaging scanner and a second medical site;
- and
- dynamically adapting a compression scheme, at the computing device, used to transport a live medical image video stream of ultrasound images from the first medical site to the second medical site based on the received feedback on network conditions for the network session, including:
- predicting, based on the feedback on network conditions, a minimum expected bit rate to transmit a compressed live video stream of high resolution medical images from the medical imaging scanner from the first medical site to the second medical site;
- selecting, in response to the expected bit rate, video compression parameters for the live video stream of medical images;
- and
- compressing the live video stream of high resolution medical images, using the selected video compression parameters.
