Catheter-based photoacoustic endoscope.

We report a flexible shaft-based mechanical scanning photoacoustic endoscopy (PAE) system that can be potentially used for imaging the human gastrointestinal tract via the instrument channel of a clinical video endoscope. The development of such a catheter endoscope has been an important challenge to realize the technique's benefits in clinical settings. We successfully implemented a prototype ...

Urogenital photoacoustic endoscope.

Photoacoustic (PA) endoscopy for human urogenital imaging has the potential to diagnose many important diseases, such as endometrial and prostate cancers. We have specifically developed a 12.7 mm diameter, rigid, side-scanning PA endoscopic probe for such applications. The key features of this endoscope are the streamlined structure for smooth cavity introduction and the proximal actuation mech...

ORBSLAM-Based Endoscope Tracking and 3D Reconstruction

We aim to track the endoscope location inside the surgical scene and provide 3D reconstruction, in real-time, from the sole input of the image sequence captured by the monocular endoscope. This information offers new possibilities for developing surgical navigation and augmented reality applications. The main benefit of this approach is the lack of extra tracking elements which can disturb the ...

Camera Motion Estimation Based on Real Endoscope Images and CT Images for Endoscope Navigation System

This paper describes a method for camera motion estimation based on real endoscope images and CT images for an endoscope navigation system. We have developed an endoscope navigation system that shows the navigation information during an endoscope examination. In this system, we need to Out side view and estimate the real endoscope camera motion. Our method tracks the camera motion by using an i...

Scanning single-mode fiber optic catheter-endoscope for optical coherence tomography.

We describe a new optical coherence tomography catheter-endoscope for micrometer-scale, cross-sectional imaging in internal organ systems. The catheter-endoscope uses single-mode fiber optics with a novel transverse scanning design. The distal end of the catheter-endoscope uses a gradient-index lens with a microprism to emit and collect a single spatial-mode optical beam with specific focusing ...
