Abstract
An endoscopically deliverable ultrasound imaging system having an ultrasound probe mounted at the end of an endoscopically deliverable catheter. The catheter connects the probe to an ultrasound imaging system. The axial or radial position of the ultrasound probe is measured by a position transducer mounted on the endocscope adjacent the biopsy port from which the catheter extends. The output of the position measuring transducer is applied to the ultrasound imaging system so that the imaging system provides an image of the tissue depth as a function of the position of the ultrasound probe.
