A real time three dimensional ultrasound imaging probe apparatus is configured to be placed inside a body. The apparatus comprises an elongated body having proximal and distal ends with an ultrasonic transducer phased array connected to and positioned on the distal end of the elongated body. The ultrasonic transducer phased array is positioned to emit and receive ultrasonic energy for volumetric forward scanning from the distal end of the elongated body. The ultrasonic transducer phased array includes a plurality of sites occupied by ultrasonic transducer elements. At least one ultrasonic transducer element is absent from at least one of the sites, thereby defining an interstitial site. A tool is positioned at the interstitial site. In particular, the tool can be a fiber optic lead, a suction tool, a guide wire, an electrophysiological electrode, or an ablation electrode. Related systems are also discussed.

Imaging probes and catheters for volumetric intraluminal ultrasound

A high speed method for presenting display of images obtained from a volumetric scanner in which multiple slices of object space are displayed simultaneously in real time thereby enabling a viewer to study relationships between various parts of the object. The slices are selectable by the viewer manipulating an icon on the display screen. Accordingly C-scans or B scans may be selected as well as I scans in which the scan plane has a selected orientation. Multiple I scans may be selected and viewed in perspective so that the viewer has an impression of a three dimensional display. Color and spectral doppler is incorporated with the scans to provide additional information of dynamic properties.
