Apparatuses and methods for medical applications and, more particularly, to steerable flexible medical devices applicable to guide tools and devices in medical procedures, including endoscopes, cameras, and catheters are provided. The apparatuses and methods also include generating a panoramic image of an interior of a branching structure at or near the distal end of the flexible medical device wherein the panoramic image is generated based on the images of the branching structure.

Method for visualization and orientation guidance during endoscopy procedure

A method for visualization guidance of device-to-image registration includes acquiring image data of a patient, generating a 3D model of the anatomy of the patient based on the image data, performing initial registration between image space and device space, advancing a device into a structure, tracking trajectory of the device in relation to the model, determining divergence between the device trajectory and the model, and effecting correction to the model or the device trajectory to minimize the divergence.

Real-time correction of regional tissue deformation during endoscopy procedure

A robot-assisted endoscope system and control methods thereof allow a user to perform intraluminal interventional procedures using a steerable sheath. A processor generates a ghost image based on a non-real-time insertion trajectory of the sheath, and a real-time image based on a real-time insertion trajectory for inserting an interventional tool through the sheath towards the target site. A display screen outputs navigation guidance data for informing a user how to manipulate the distal section of the sheath towards the target site such that the real-time image overlaps or coincides with at least part the ghost image and the real-time insertion trajectory becomes aligned with the non-real-time insertion trajectory.

Intraluminal navigation using ghost instrument information

An apparatus for correction of a direction to which a tool channel or a camera moves or is bent in a case where a displayed image is rotated. The apparatus includes at least one memory and at least one processor that executes instructions stored in the memory to receive a directional command of a capturing direction of a camera, move the capturing direction of the camera according to the received directional command, detect a rotation amount of a captured image displayed on a monitor, wherein the captured image is captured by the camera, and correct, based on the detected rotation amount, directional information corresponding to a particular directional command or directional coordinate for moving the camera, wherein the directional information is used for moving the capturing direction of the camera.
