Abstract: An unmanned autonomous vehicle is provided and includes at least one propulsion device, at least one image capture device, at least one adjusting member to adjust an tilt angle of the image capture device and is configured to receive, from a control device, a capturing instruction to capture at least one image, acquire angle information indicating a tilt angle of the image capture device, and control, in a case where the capturing instruction is received, the propulsion device so that the image capture device captures at least one image at an altitude which is determined based on the acquired angle information.

Abstract: A connector, a bayonet-style connector, and methods for using the connector or bayonet-style connector are provided. At least one connector includes a receiver having an inner volume to receive a connector, and having a pawl; and a pushbutton or actuator that operates to move or unlock the pawl so that a user can insert and lock and/or unlock and remove the connector using only a single hand of the user. At least one bayonet-style connector includes a connector portion having an opening; a receptacle portion that operates to slidingly accept the connector portion and that has a pawl that operates to engage with the opening to lock the connector portion in place; and an actuator that operates to impart force on the pawl to unlock the connector portion so that a user can remove the connector portion using only one hand of the user.

Abstract: Devices, systems, and methods calculate a first stenosis measurement of a measured location in a lumen based on optical-imaging data of the lumen, on the measured location in the lumen, and on a first reference location in the lumen; and generate a screen that includes a tomographic view of the lumen, a longitudinal view of the lumen, and the first stenosis measurement, wherein the tomographic view of the lumen and the longitudinal view of the lumen are based on the optical-imaging data of the lumen, wherein the tomographic view includes a tomographic-view measured-location indicator that indicates the measured location in the lumen and a first tomographic-view reference indicator that indicates the first reference location in the lumen, and wherein the longitudinal view includes a longitudinal-view measured-location indicator that indicates the measured location in the lumen and a first longitudinal-view reference indicator that indicates the first reference location in the lumen.

Abstract: Embodiments disclosed herein provide systems, methods and/or computer-readable media for automatically detecting and removing fluorescence artifacts from catheter-based multimodality OCT-NIRAF images. In one embodiment, a process of determining an automatic threshold value (automatic thresholding) is implemented by sorting characteristic parameter values of the NIRAF signal and finding a maximum perpendicular distance between a curve of the sorted values and a straight line from the highest to the lowest sorted value, combined with the use of unsupervised machine learning classification techniques to detect the frame's NIRAF values that correspond to signal artifacts. Once the signal artifacts are detected, the system can filter out the signal artifacts, correct the frames that had artifacts, and produce a more accurate multimodality image.

Abstract: A fiber optics polarization controller comprises: an optical fiber and multiple polarization stages. A first stage comprises: a motor having a hollow shaft spanning from a proximal end to a distal end along a rotational axis; and a fiber paddle affixed to and adapted to rotate with the hollow shaft. The fiber paddle has a ring-shaped body with two openings arranged opposite to each other around the ring-shaped body. A first opening of the fiber paddle is connected to the distal end of the hallow shaft substantially collinear with the rotational axis of the motor. The optical fiber is arranged spanning through the hollow shaft, entering the fiber paddle through the first opening, following around the ring-shaped body to form a fiber loop, and exiting the ring-shaped body through the second opening. A second stage is arranged in series with the first stage.

Abstract: A method for processing an intravascular image including a plurality of image frames acquired during a pullback of an imaging catheter inserted into a vessel, the method including displaying on a graphical user interface (GUI) an image including detected results of lumen borders and at least one stent, the image including an evaluated stent expansion and an evaluated stent apposition determined from the intravascular image. The method also includes determining whether a modification to the detected results of the stent has been received by the GUI. Then, re-evaluating stent length, stent expansion and stent apposition when it is determined that the detected results of the stent has been modified via the GUI and displaying the re-evaluated stent expansion and the re-evaluated stent apposition on the GUI.
