PROJECT TITLE :

Development of Multisegment Steering Mechanism and 3-D Panorama for Automated Bladder Surveillance System

ABSTRACT:

A cystoscope is an invaluable tool for bladder cancer surveillance and lower urinary tract pathology diagnosis. The performance of cystoscopy will be improved by automating the procedure to make sure fast and complete inspection, having a predicted pathway for imaging. This paper proposes a versatile, wire-driven, multisegment mechanism for steering an imaging probe to follow optimal, preprogrammed scan trajectories. A novel versatile imaging probe scanning fiber endoscope (SFE) of one.2 mm in diameter generates high-quality reflectance or fluorescent pictures. A three-D panoramic reconstruction view of the bladder is generated by custom software to confirm comprehensive surveillance and improve clinical potency. The kinematics and controllability of the proposed mechanism are analyzed. The multiple degrees-of-freedom of the mechanism provide the advantage of maintaining the camera perpendicular to the bladder wall with a safety distance. The measured experimental results show 8.one% and 5.one% tip position and orientation errors, respectively, to the theoretical simulation predictions. At intervals a synthetic bladder phantom made from patient-specific geometry information, the equipment is able to come up with a 3-D panorama of about 60percent of the bladder's inner surface, whereas accepting fifty% image overlap between adjacent pictures. The novel imaging capability of the SFE, combined with a robotized multisegment steering mechanism and a picture stitching software, proposes potential advancements to the multimodal 3-D panorama of the bladder.
