摘要： 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.

摘要： One or more devices, systems, methods, and storage mediums for imaging and for minimally invasive medical devices, such as, but not limited to, for intravascular ultrasound (IVUS), spectrally encoded endoscopy (SEE), and/or Optical Coherence Tomography (OCT), are provided herein. One or more embodiments may involve imaging reconstruction using a real-time signal of a rotary position from a near distal end encoder. One or more devices, systems, methods and storage mediums may include, in one or more embodiments, a rotary encoder or sensor to detect an angular position of a rotary shaft or a drive cable, for example, to reduce imaging Non-Uniform Rotational Distortion. Examples of such applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, for Gastro-intestinal, cardio and/or ophthalmic applications, and being obtained via one or more optical instruments.

摘要： One or more devices, systems, methods, and storage mediums for optical imaging medical devices, such as, but not limited to, Optical Coherence Tomography (OCT), single mode OCT, and/or multi-modal OCT apparatuses and systems, and methods and storage mediums for use with same, for calculating lumen distance(s), including based on real-time A-line signal(s), are provided herein. Examples of applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, for Gastro-intestinal, cardio and/or ophthalmic applications, and being obtained via one or more optical instruments, such as, but not limited to, optical probes, catheters, capsules and needles (e.g., a biopsy needle). Fast A-line lumen segmentation methods, which can be applied real-time to a whole arterial pullback, and devices, systems, and storage mediums for use with same, are provided herein. Techniques provided herein also improve processing efficiency and decrease calculations while achieving measurements that are more precise.

摘要： A catheter system includes an electronic console; a catheter having a proximal end attachable to the console and a distal end configured to house therein an optical probe; an optical fiber configured to transmit from the console to the optical probe excitation radiation of a first wavelength, and configured to return to the console an optical response signal having a second wavelength longer than the first wavelength; a detector configured to detect intensity of the optical response signal; and a processor configured to determine, based on the detected intensity of the optical response signal, whether the catheter is properly connected to the console. The optical response signal is generated within the optical fiber itself in response to transmitting the excitation radiation therethrough. The optical response signal is an auto-fluorescence signal and/or Raman scattering signal generated from the optical fiber itself.

摘要： Detecting a vessel region in multiple angiographic image frames and defining a direction that perpendicularly intersects a longitudinal direction of the vessel region to improve co-registration between two imaging modalities. Motion of the vessel region is then detected based on the direction that intersects the longitudinal direction of the vessel region by evaluating positions of the vessel region in the multiple angiographic image frames. The method includes defining an area based on the detected motion and the detected vessel region, detecting a marker of an imaging catheter disposed in the vessel region within the area and performing co-registration based on the detected marker.

摘要： An apparatus for classifying a contrast level of an image is provided. One or more processors execute instructions stored in one or more memory devices which configure the one or more processors to obtain an image from an image source, extract intensity values for each pixel of the obtained image, calculate a probability distribution for the obtained image representing a number of pixels at each unique pixel value, determine, from the calculated probability distribution, a spread value representing a series pixel values including at least a predetermined number of pixels at each pixel value in the series of pixel values and classify the obtained image a member of one of three classes based on the calculated probability distribution and the determined spread value.
