ABSTRACT:
An endoscopic ultrasound probe has a rotatable transducer array for obtaining two-dimensional cross-sectional images of a subject along a variety of scan planes. The probe has take-up mechanism comprising a flexible cable assembly which electrically connects the array to remote ultrasound imaging system electronics. The flexible cable assembly is attached to the array within a first volume and is disposed in a second volume. As the array rotates, the take-up mechanism produces changes in the amount of the flexible cable within the second volume corresponding to changes in the amount of flexible cable within the first volume.
