Abstract: A method and apparatus for automated detection of a general, non-sinusoidal type of periodicity in ultrasound Doppler signals from pulsatile blood flow is described. The method computes a measure of pulsatility from the power spectrum near the peaks of the fundamental and harmonic frequencies of the Doppler signal information.

Abstract: According to an aspect, there is provided a computer-implemented method of operating a visual data delivery system. The method comprises: processing (901) a sequence of 3-dimensional, 3D, images of a body to generate first 2-dimensional, 2D, image data representing a first sequence of 2D images of the body, wherein the 2D images are images of the body in a 2D image plane through the 3D images, and wherein an amount of data representing the first 2D image data is less than an amount of data representing the 3D images from which the first 2D image data is generated; sending (903) the first 2D image data to a display system for display of the first sequence of 2D images of the body by the display system; receiving (905) a 2D image plane adjustment indication from the display system, wherein the 2D image plane adjustment indication indicates a required rotation and/or translation of the 2D image plane; processing (907) the sequence of 3D images and/or a further sequence of 3D images to generate second 2D image data representing a second sequence of 2D images of the body, wherein the 2D images in the second sequence of 2D images are images of the body in the rotated and/or translated 2D image plane; and sending (909) the second 2D image data to the display system for display of the second sequence of 2D images of the body by the display system.
