The invention generally relates to medical imaging systems that instantly and/or automatically detect borders. Embodiments of the invention provide an imaging system that automatically detects a border at a location within a vessel in response only to navigational input moving the image to that location. In some embodiments, systems and methods of the invention operate such that when a doctor moves an imaging catheter to a new location with in tissue, the system essentially instantly finds, and optionally displays, the border(s), calculates an occlusion, or both.

System and method for instant and automatic border detection

Systems, devices, and methods for displaying multiple intraluminal images in a luminal assessment are provided. An intraluminal imaging device is provided which is configured to be positioned within a body lumen of a patient and receive imaging data associated with the body lumen. The intraluminal imaging device may be in communication with a controller configured to display two or more transverse images of the body lumen on a single display device. The system may also be configured to automatically measure, display, and compare measurements of features, including misalignment or malapposition of a stent, the diameter and area of the stent at various locations along the stent, as well as the diameter and area of the lumen before the stent is positioned.

Systems, devices, and methods for displaying multiple intraluminal images in luminal assessment with medical imaging

Systems, methods, and devices are provided for automatically adjusting the scale or magnification of an intraluminal image on a display of an intraluminal imaging system based on a measured or computed size of the vessel. For example, a system may include a processor configured to receive, from an intraluminal imaging catheter or guidewire, a first intraluminal image of a body lumen, and compute a dimension of an anatomical feature of the body lumen based on the first intraluminal image. The processor computes a scaling factor for the first intraluminal image based on the dimension of the body lumen, scales the first intraluminal image by the scaling factor, and outputs the scaled first intraluminal image to a display in communication with the processor circuit.

Systems, devices, and methods for providing procedure-specific workflow guidance are provided. The workflow guidance may include providing selectable options on a display device to a user including a selectable option to select a target vessel and a prompt to move an intravascular imaging device within the selected target vessel. Imaging data is received from the intravascular imaging device within the selected target vessel. The workflow guidance may be used to identify an area of interest within the selected target vessel and automatically display vessel measurements corresponding with the area of interest on the display device.

Systems and methods for multi-modality data processing are provided. Some embodiments are particularly directed to navigating sets of multi-modality medical data in a multi-modality processing system. In one embodiment, a method for navigating medical data in a medical processing system includes receiving a reference set of medical data by the medical processing system, where the medical data corresponds to a modality selected from the group consisting of: FFR, iFR, pressure, flow, IVUS, and OCT. The medical processing system also receives a navigation command. An enhancement and a subset of the reference set of medical data to enhance are identified based on the navigation command. The medical processing system performs the selected enhancement on the subset of data and the enhanced subset is displayed. The enhancement may include performing a single-axis zoom on the subset.

An extension cable is adapted for use in an intravascular ultrasound system. It has a first connector, for connecting to a catheter and a second connector for connecting to a patient interface module. A cable arrangement provides power transmission, data transmission and data signal processing (amplification or regeneration) between the first and second connectors. The extension cable enables sterility to be maintained in a workflow in a time efficient and easy manner as the catheter to extension cable connection may remain in a sterile environment.

Devices, systems, and methods for evaluating a vessel of a patient are provided. The method includes outputting, to a touch-sensitive display of a bedside controller, a screen display including: a visual representation of a first pressure ratio of pressure measurements obtained by first and second instruments positioned within a vessel while the second instrument is moved from a distal position to a proximal position relative a stenosis and the first instrument remains stationary; and a first proximal pressure waveform and a first distal pressure waveform; receiving, through the touch-sensitive display of the bedside controller, a user touch input on the first proximal pressure waveform and/or the first distal pressure waveform identifying a time at which pressure measurements were obtained; and modifying the screen display, in response to the user touch input, to further include a visual representation of the obtained pressure measurements corresponding to the identified time.

Systems and methods for multi-modality data processing are provided. Some embodiments are particularly directed to labeling and indexing multi-modality medical data. In one embodiment, a method for labeling medical data received by a multi-modality medical processing system includes receiving, by the medical processing system, medical data to be labeled. A reference set of labels corresponding to the medical data is presented at a display device. A selection of a first label from the reference set of labels is received from an interface device. A target set of labels corresponding to the medical data is presented at the display device, the target set of labels based on the first label. A selection of a second label from the target set of labels is received from the interface device. The medical data is then labeled based on the first and second labels.

Data labeling and indexing in a multi-modality medical imaging system

Generally, the present disclosure is directed to displaying patient medical data in a multi-modality medical processing system. The method and system described herein present medical data in multiple different modalities on a single user interface screen, allowing a practitioner viewing the user interface to manage all acquired data sets associated with a patient regardless of modality. As such, the amount of time a practitioner must spend reviewing patient medical data is reduced, leading to more efficient diagnosis and treatment. Further, multiple patient cases corresponding to different patients may be presented on a single user interface screen to simplify multi-patient case management.

Multi-modality case explorer system and method

Systems and methods for multi-modality data processing are provided. Some embodiments are particularly directed to interpreting gesture-based commands in a multi-modality processing system. In one embodiment, a method for interpreting user input in a medical processing system includes receiving a state designator corresponding to a mode of operation of the medical processing system, where the mode of operation includes a value representative of a modality selected from the group consisting of: IVUS, OCT, pressure, and flow. A list of active commands is generated based on the received state designator. A user input sequence is received from one or more user input devices. The medical processing system correlates the user input sequence to a command of the list of active commands, and the command is utilized to control operation of a component of the system. The list of active command may include a subset of commands common to multiple modalities.
