Abstract: An apparatus includes a bendable body including at least a distal bending portion and a proximal bending portion, a first driving mechanism for bending the distal bending portion, a second driving mechanism for bending the proximal bending portion, a controller that controls the first driving mechanism to bend the distal bending portion and controls the second driving mechanism to bend the proximal bending portion, and a receiving unit that receives a command on an amount of bending of part or all of the bending portions. The controller is configured to switch between first control for bending only the distal bending portion according to the command received by the receiving unit and second control for bending the distal bending portion and the proximal bending portion so that the distal bending portion and the proximal bending portion have constant curvature according to the command received by the receiving unit.

Abstract: A robotic catheter system and methods for implementing corrective actions during use thereof. A method comprises: providing a catheter that has one or more bendable segments and a catheter tip, inserting the catheter into a bodily lumen and navigating the catheter through the lumen along an insertion trajectory while an actuation unit applies an actuation force to the one or more bendable segments; recording a navigation parameter in relation to the insertion trajectory while the catheter is moved through the lumen, displaying, on a display, a graphical representation of the navigation parameter relative to a threshold value indicative of a location along the insertion trajectory where a navigation error of the catheter can occur or has occurred; and outputting to the display an interactive user-guide showing one or more than one corrective actions that can be taken to correct and/or prevent the navigation error.

Abstract: A method for intravascular image processing carries out steps of acquiring intravascular data of a portion of a lumen, determining a region of interest based on characteristics of the acquired data, determining an angle (orientation) for displaying an initial longitudinal view of the portion of the lumen based on the determined region of interest, and displaying the initial longitudinal view based on the determined angle and displaying a tomographic view of the portion of the lumen.

Abstract: An apparatus is provided and connects to a first server. The apparatus receives a first video stream of a captured image captured by a first camera connected to the first server and receives a second video stream of a part of the captured image captured by the first camera. A participant ID is assigned to the first video stream and a virtual participant ID is assigned to the second video stream.

Abstract: 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.

Abstract: One or more devices, systems, methods and storage mediums for performing medical procedure (e.g., needle guidance, ablation, biopsy, etc.) planning and/or performance, and/or for performing registration using at least one mask, are provided. Examples of applications for such devices, systems, methods and storage mediums include imaging, evaluating and diagnosing biological objects, such as, but not limited to, lesions and tumors, and such devices, systems, methods and storage mediums may be used for radiotherapy applications (e.g., to determine whether to place seed(s) for radiotherapy). The devices, systems, methods and storage mediums provide improved registration results by utilizing at least one mask to suppress one or more artifacts or objects (which may or may not include, but is not limited to, at least one medical instrument or tool) in an image including a portion of the medical guidance device and/or to enhance a region or target of interest in the image.
