    Abstract: Ultrasound acquisition Information about a structure (701) within a body is acquired by providing data defining a non-straight line (42b), at least a part of which corresponds to the structure (701); transmitting an ultrasound transmit signal (44b) into the body; receiving reflections (400-402) of the transmit signal (44b); processing the received reflections (400-402) so as to trace the focal point (403-405) of a receive beam along the path of the non-straight line (42b); using reflections (400-402) of the transmit signal (44b) from along the non-straight line (42a) to acquire information about the structure (701).

    Abstract: A method for burning gas in a burner, including leading the gas through an inner fuel tube and introduction of combustion air through an annular space surrounding the inner fuel tube. This space forms of an outer tube terminated by a conically converging section, wherein the end of the inner fuel tube forms a burner head. The major part of the primary gas is introduced into the upstream end of the burner head, to go into the combustion air that flows past the burner head, whereas a smaller part of a secondary gas is introduced into the free end of the burner head and into the constricted part of the annular channel that surrounds the burner head. The gas flow is accelerated past the burner head due to the reducing cross section and is burned downstream in relation to the burning head.

    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.
