Abstract

Systems and methods for network-based ultrasound imaging are provided, which can include a number of features. In some embodiments, an ultrasound imaging system images an object with three-dimensional unfocused pings and obtains digital sample sets from a plurality of receiver elements. A sub-set of the digital sample sets can be electronically transferred to a remote server, where the sub-set can be beamformed to produce a series of two-dimensional image frames. A video stream made up of the series of two-dimensional images frames can then be transferred from the remote server to a display device.

First claim

What is claimed is:

1. A method of ultrasound imaging comprising, the steps of:
transmitting an unfocused three-dimensional ping into an object from a transmitter element of a transducer array in a probe of a data capture device;
receiving echoes of the unfocused three-dimensional ping from one or more reflectors with a plurality of receiver elements of the transducer array;
converting analog signals from each of the plurality of receiver elements into a dataset of digital sample sets from all the receiver elements;
beamforming the dataset of digital sample sets locally with the data capture device with first beamforming and image generation parameters to generate a first ultrasound image;
displaying the first ultrasound image to a first operator of the data capture device; communicating at least a portion the dataset of digital sample sets to a network-based image generation system;
beamforming the dataset of digital sample sets remotely with the network-based image generation system with second beamforming and image generation parameters different than the first beamforming and image generation parameters to generate a second ultrasound image;
displaying the second ultrasound image to a second operator of the network-based image generation system.

2. The method of claim 1 , further comprising transmitting a second unfocused three-dimensional ping into an object from a second transmitter element, and repeating the receiving, converting, beamforming, displaying, communicating, beamforming, and displaying steps for the second unfocused three-dimensional ping.

3. The method of claim 1 wherein, in response to a control signal, transferring the dataset from the data capture device to the network-based image generation system and storing the dataset at the network-based image generation system.

4. The method of claim 1 , further comprising displaying the first ultrasound image on a display device that is physically attached to the data capture device.

5. The method of claim 1 , further comprising displaying the first ultrasound image on a display device that is not physically attached to the data capture device.

6. The method of claim 5 , wherein the display device is a mobile device.

7. The method of claim 1 , wherein beamforming the dataset remotely with the network-based image generation system does not change the first ultrasound image displayed to the first operator.

8. The method of claim 1 , wherein a difference between the first beamforming and image generation parameters and the second beamforming and image generation parameters comprises an adjustment to speed-of-sound values.

9. The method of claim 1 , wherein a difference between the first beamforming and image generation parameters and the second beamforming and image generation parameters comprises an adjustment to zoom level.

10. The method of claim 1 , wherein a difference between the first beamforming and image generation parameters and the second beamforming and image generation parameters comprises an adjustment to pan window.

11. The method of claim 1 , wherein a difference between the first beamforming and image generation parameters and the second beamforming and image generation parameters comprises an adjustment to weighting factors.

12. The method of claim 1 , wherein a difference between the first beamforming and image generation parameters and the second beamforming and image generation parameters comprises an adjustment to image layer combining algorithms.

13. The method of claim 1 , wherein the second beamforming and image generation parameters are received as an input from the second operator.
