1. A method for content-based rendering based on machine learning in a rendering system, the method comprising:
- loading, from memory, a medical dataset representing a three-dimensional region of a patient;
applying, by a machine, the medical dataset to a machine-learnt model, the machine-learned model trained with deep learning to extract features from the medical dataset and trained to output values for two or more physically-based rendering parameters based on input of the medical dataset, the two or more physically-based rendering parameters being settings of a physically-based renderer, the settings used by the physically-based renderer to control rendering from three dimensions to two-dimensions, at least one of the two or more rendering parameters being controls for data consistency handling, lighting design, viewing design, material propriety, or internal renderer property;
rendering, by the physically-based renderer, a photorealistic image of the three-dimensional region of the patient using the output values resulting from the applying as the settings to control the rendering from the medical dataset, the rendering of the medical dataset of the three-dimensional region being to the photorealistic image in the two-dimensions; and
transmitting the photorealistic image.

Abstract
An artificial intelligence agent is machine trained and used to provide physically-based rendering settings. By using deep learning and/or other machine training, settings of multiple rendering parameters may be provided for consistent imaging even in physically-based rendering.

11. A method for machine training for content-based rendering in a machine training system, the method comprising:
-
inputting first volume data of a volume of a patient, a first image of the volume, and first values of path tracing rendering parameters to training of an artificial intelligence, the path tracing rendering parameters being settings to control rendering from the volume to a two-dimensional image; machine training, with a machine, the artificial intelligence to output second values of the path tracing rendering parameters for a second volume data where the second values control the rendering from the volume to provide a second rendered image of the second volume modeled on the first image; and storing the trained artificial intelligence. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A system for content-based rendering based on machine learning, the system comprising:
-
a medical scanner configured to scan a patient; a machine configured to output settings for rendering parameters by application of data from the scan to a machine-learnt model, the rendering parameters being controls for performing rendering from a volume to a two-dimensional image, the rendering parameters including windowing, transfer function, and lighting, and the settings learned to provide a first image from the data similar to one or more second images for a same diagnostic context; and a graphics processing unit configured to render the first image from the data using the settings output by the application of the data to the machine-learnt model, the first image being a two-dimensional representation. - View Dependent Claims (23, 24)
