Abstract
An example system includes a medical imaging device, a server, a computing device, and a display. The server can be configured to convert images and/or any other medical data from the medical imaging device into Hyperspherical Harmonic representations to compress, index, search, process, and retrieve the medical data. The computing device can be configured to access the images, medical data, and Hyperspherical Harmonic representations stored on the server to improve radiotherapy and other forms of medical treatment.
Claims20
A computer-implemented method comprising:
- determining a set of (n−1)-dimensional sample points in a spherical coordinate system;
- calculating, at a respective coordinate of each of the set of (n−1)-dimensional sample points, respective values of individual n-dimensional Hyperspherical Harmonic (HSH) basis functions up through a given maximum order;
- converting n-dimensional medical data into an HSH representation;
- and
- constructing an approximation of the n-dimensional medical data from the HSH representation.
A computer-implemented method for performing a radiotherapy task comprising:
- receiving a first HSH representation of first n-dimensional medical data;
- receiving a second HSH representation of second n-dimensional medical data;
- inputting the first HSH representation and the second HSH representation into a trained machine learning model;
- and
- predicting, using the trained machine learning model, a third HSH representation of third n-dimensional medical data.
A system comprising:
- a medical imaging device;
- a server operably coupled to the medical imaging device, wherein the server is configured to:
- receive a medical image from the medical imaging device;
- convert the medical image into an hypespherical harmonic (HSH) representation by:
- determining a set of (n−1)-dimensional sample points in a spherical coordinate system;
- calculating, at a respective coordinate of each of the set of (n−1)-dimensional sample points, respective values of individual n-dimensional HSH basis functions up through a given maximum order;
- converting n-dimensional medical data into an HSH representation;
- and
- constructing an approximation of the n-dimensional medical data from the HSH representation;
- a computing device in operable communication with the server by a network;
- and
- a display operably coupled to the computing device;
- wherein the computing device is configured to:
- retrieve, from the server, the HSH representation;
- and
- output a depiction of the HSH representation for display to a user;
- and
- in response to a user input, retrieve from the server, the medical image;
- and
- output a depiction of the medical image for display.
