Network-based ultrasound imaging system
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.
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 full dataset of digital sample sets, wherein the full dataset comprises digital sample sets from all the receiver elements;
communicating the full dataset to a network-based image generation system;
in the network-based image generation system,
combining digital sample sets from a plurality of the receiver elements to represent a three-dimensional location of each reflector as a voxel in a 3D volume;
selecting a first voxel within the 3D volume;
identifying closest digital sample sets within the full dataset to the selected first voxel for each receiver element;
summing the closest digital sample sets to produce a final representation of the selected first voxel.
2. The method of claim 1 , further comprising repeating the selecting, identifying, and summing steps for a plurality of selected voxels.
3. The method of claim 1 where the final representation of the selected first voxel is made up of combined data from a plurality of receiver elements.
4. 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, communicating, combining, selecting, identifying, and summing steps or the second unfocused three-dimensional ping.
5. The method of claim 1 , further comprising coherently combining the closest digital sample sets when the receiver elements fall within the same coherence window.
6. The method of claim 1 , further comprising incoherently combining the closest digital sample sets when the receiver elements fall outside of the same coherence window.
7. The method of claim 1 , further comprising coherently or incoherently combining the voxels of the 3D volume to form a 3D image.
8. The method of claim 7 , further comprising extracting a 2D slide of pixels from the 3D volume to form a two-dimensional image.
9. The method of claim 8 , further comprising selecting a desired two-dimensional image with a user interface.
