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).
