    Abstract: A method of processing cardiac ultrasound data for determining information about a mechanical wave in the heart. The method comprises receiving data representative of a time series of three-dimensional data frames, generated from ultrasound signals from a human or animal heart, each frame comprising a set of voxels, each voxel value representing an acceleration component of a respective location in the heart at a common time. The method also comprises identifying, for each voxel, a frame of the series in which the voxel value is at a maximum. A three-dimensional time-propagation data set is generated by assigning each voxel a value representative of the time of the respective frame in the time series for which the corresponding voxel is at a maximum. The method then comprises generating data representative of a three-dimensional velocity vector field by calculating time derivatives from the three-dimensional time-propagation data set.

    Abstract: A surgical cutting tool for keyhole surgery comprises: a handle 2 at a proximal end of the tool; an elongate member 4 extending from the handle to a distal end of the tool; and a saw 6 at the distal end of the tool, the saw being supported by the elongate member 4. The elongate member 4 has a length allowing for insertion of the saw 6 into the body by a distance of at least 150 mm. The tool is arranged for insertion of the saw 6 into the body during keyhole surgery; and the saw 6 is able to cut bone when pressed against the bone.
