Abstract: Disclosed herein are planning, navigation and simulation systems and methods for minimally invasive image-guided percutaneous intervention in which the planning method and system use patient-specific pre-operative images and instrument-specific parameters to generate a planned insertion path. A system includes a needle guide device that interfaces with a computing device to guide a needle-like probe towards target location within an anatomy of a subject. The computing device includes a processor configured to receive volumetric image data of the anatomy of the subject, and data about parameters of the needle guide device. One or more algorithms executed by the processor provide direct visualization of a parametric contour map superposed on an image of the patient's skin surface. A user can choose an optimal insertion point for the planned insertion path based the parametric contour map.

Abstract: A method and system for editing a lumen contour of a tomographic image. A method comprises: receiving image data corresponding to a plurality of tomographic images acquired by an imaging catheter scanning a blood vessel; obtaining, by a processor, an automatically-generated lumen contour of the blood vessel from a tomographic image of the blood vessel; displaying, on a display, the automatically-generated lumen contour overlaid on the tomographic image of the blood vessel; identifying a true lumen edge of the blood vessel in the tomographic image; estimating a percentage of matching between a shape of the automatically-generated lumen contour to a shape of the true lumen edge; and receiving editing operations from a user via a touchscreen interface for editing at least part of the automatically-generated lumen contour based on the estimated percentage of matching. Plural editing modes are available based on the percentage of matching meeting one or more thresholds.

Abstract: One or more devices, systems, methods and storage mediums for performing optical coherence tomography (OCT) while detecting one or more lumen edges, one or more stent struts, and/or one or more artifacts are provided. 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). Preferably, the OCT devices, systems methods and storage mediums include or involve a method, such as, but not limited to, for removing the detected one or more artifacts from the image(s).

Abstract: 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 viewing, controlling, updating, and emphasizing imaging modalities, for performing angio delay determination to find relative delay difference(s) between angio image(s) and another modality image(s), and/or for performing synchronization technique(s) are provided herein. One or more embodiments provide at least one intuitive Graphical User Interface (GUI), method, device, apparatus, system, or storage medium to comprehend information, to improve or maximize accuracy in one or more images and to perform angio delay (or delay time) determination and/or synchronization. In addition to controlling one or more imaging modalities, the GUI may operate for one or more applications, including, but not limited to, angio delay measurement(s), synchronization, co-registration, and imaging.
