A system and method for controlling the heat of an ultrasonic transducer is disclosed. The presently preferred embodiments of the present invention control the temperature of the transducer face by changing the imaging modes of the system. In a preferred embodiment, feedback from temperature sensing elements placed in the transducer is used to determine when to switch from a higher power imaging mode to a lower power imaging mode. In another preferred embodiment, the system switches from a higher power imaging mode to a lower power imaging mode after a predetermined period of time has elapsed. In yet another preferred embodiment, the system switches to a “mixed” imaging mode, where the system cycles rapidly between a higher power imaging mode and a lower power imaging mode, and the resulting data is combined to form a single image.

A semi-invasive ultrasound imaging system for imaging biological tissue includes a transesophageal probe or a transnasal, transesophageal probe connected to a two-dimensional ultrasound transducer array, a transmit beamformer, a receive beamformer, and an image generator. The two-dimensional transducer array is disposed on a distal portion of the probe's elongated body. The transmit beamformer is connected to the transducer array and is constructed to transmit several ultrasound beams over a selected pattern defined by azimuthal and elevation orientations. The receive beamformer is connected to the transducer array and is constructed to acquire ultrasound data from the echoes reflected over a selected tissue volume. The tissue volume is defined by the azimuthal and elevation orientations and a selected scan range. The receive beamformer is constructed to synthesize image data from the acquired ultrasound data. The image generator is constructed to receive the image data and generate images that are displayed on an image display. Preferably, the image generator is constructed to generate, from the image data, several orthographic projection views over the selected tissue volume.

A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device () in three dimensions. An interventional system () is used to operate the invasive medical device () and produces spatially-based information relating to the activity of the invasive medical device (). The spatially-based information from the interventional system () is merged into the three dimensional ultrasonic image data to produce a live three dimensional image of the invasive medical device () or its activity. In one embodiment the locations where the activity of the invasive medical device () is performed is recorded and displayed in the three dimensional ultrasonic image. The three dimensional ultrasonic image may be shown as an anatomical volume rendered image or as a wire frame model () of the anatomy. In another embodiment an integrated three dimensional ultrasonic imaging and invasive device system is described.

Control mechanism () for an endoscope including first and second independently rotatable control knobs (), an inner pinion shaft () fixed to the first control knob (), an outer pinion shaft () fixed to the second control knob () and coaxial with the inner shaft () and an intermediate shaft () arranged at least partially inside of the outer shaft () and at least partially around the inner shaft (). O-rings () between the intermediate shaft () and the inner and outer shafts () seal the interior of the endoscope and transfer torque from the inner or outer shaft () to the intermediate shaft (), which is grounded against rotation and therefore does not transfer torque to the other shaft (). A non-cross-coupling control mechanism is achieved in which the rotation of one control knob and its associated shaft does not have any effect on the other control knob and associated shaft.
