ABSTRACT:
A transducer array is connected with a catheter housing. As the transducer array is rotated, the catheter housing also rotates. As a result, at least a portion of the catheter housing twists about a longitudinal axis. By applying rotation in a controlled way, such as with a motor, a plurality of two-dimensional images for three-dimensional reconstruction may be obtained. The rotation of the catheter housing may limit the total amount of rotation of the array, such as rotating the array through a 90 degree or less amount of rotation about the longitudinal axis. The housing of the catheter is formed with a soft section. The softer material allows for a greater amount or increased ease for twisting the catheter.
