An ultrasonic diagnostic imaging system is described which utilizes one or more transducer arrays affixed to the head of a patient to diagnose and treat stroke victims. The transducer headset produces a two or three dimensional image of the vasculature inside the cranium, preferably assisted by a microbubble contrast agent. A vascular flow map is produced by the system which may be diagnosed for signs of a blood clot. If a blood clot is detected, a therapeutic beam is transmitted while the contrast agent is present to break up the blood clot by the disruption of microbubbles. The headset may also be used in a monitoring application to detect the recurrence of blood clots in a stroke victim.

A device (D) is intended for producing images of heating tines (HT) coupled to a needle (N) positioned near a chosen tissue part of tissues located in an area of a body. This device (D) comprises i) a means (ME) for estimating tissue thermal strains, induced by means of the heating tines (HT) into the tissue surrounding the chosen tissue part, from received ultrasound image data, and for deducing relative positions of these heating tines (HT) to the chosen tissue part from the estimated tissue thermal strains, and ii) a means (MC) for combining the received ultrasound image data with position data representative of the deduced relative positions to produce images of the area with thermal strain information showing the relative positions of the heating tines (HT) to the chosen tissue part.
