Abstract: A system and method is provided for controlling an acquisition system to obtain, based on a currently acquired set of projection data, a next set of projection data that is to be acquired using a set of learned imaging conditions. The set of learned imaging conditions are, at least in part, based on training data including projection data and dose information. In one embodiment, the initial dose and angle for obtaining the initial set of projection data are chosen at random. In another embodiment, the initial dose and angle for obtaining the initial set of projection data are chosen based on a test scan and a trained neural network for outputting the initial dose and angle using a loss function.

Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires image data including image data of a blood vessel of a subject. The processing circuitry performs analysis related to the blood vessel by using the image data, and specifies a region of interest in the blood vessel based on a result of the analysis. The processing circuitry performs fluid analysis on a region other than the region of interest at a first accuracy, and performs fluid analysis on the region of interest at a second accuracy that is higher than the first accuracy.

Abstract: A system, method and computer readable medium to render, as a single image, source data from a network of data providers, that provide source data of a respective data type. A composition space contains two-dimensional (2D) display surfaces to which the source data is provided from the data providers, and transformation operator surfaces, which are located at different positions in a depth direction than the 2D display surfaces. Each of the transformation operator surfaces represent a respective visual transformation operation on surfaces of the 2D display surfaces that are positioned at lesser depths than the transformation operator surface. Using data-centric communication, updates are published to the 2D display surfaces, the updates including the source data from the data providers, and, upon detecting an update to a subscribed 2D display surface, the subscribed 2D display surface is rendered as the single image by performing the visual transformation operations.
