摘要： Disclosed is an intravascular imaging system, including a processor circuit configured for communication with an intravascular imaging catheter that is sized and shaped for positioning within a lumen of a blood vessel. The processor circuit configured to receive a plurality of intravascular images obtained by the intravascular imaging catheter while the intravascular imaging catheter is positioned within the lumen, wherein the plurality of intravascular images corresponds to a plurality of locations along a length of the blood vessel. The processor is further configured to determine a measurement associated with the lumen for each image of the plurality of intravascular images, generate a curve representative of a change in the measurement along the length of the blood vessel, detect a condition of the blood vessel based on the curve, and display a graphical representation of the condition.

摘要： Disclosed is an intraluminal imaging system, including an intraluminal imaging catheter or guidewire configured to be positioned within an anatomy of a patient, and a processor circuit in communication with the imaging catheter or guidewire, wherein the processor circuit is configured to receive a plurality of cross-sectional images of the anatomy from the imaging catheter or guidewire. The processor is further configured to compute, using image processing of at least one of the cross-sectional images, a value of the anatomy, estimate a cross-sectional shape of the anatomy to be circular, calculate a diameter of the anatomy based on the computed value and the estimated circular shape, and output the diameter of the anatomy to a display.

摘要： 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.

摘要： A system includes a processor circuit that receives intraluminal images obtained by an intraluminal imaging device during movement through a patient’s body lumen. The processor circuit outputs, to a display, a visual representation of user guidance in response to the processor circuit identifying, among the intraluminal images, a candidate intraluminal image. The user guidance includes stopping the movement and instructing the patient to initiate deep breathing. The processor circuit receives additional intraluminal images obtained by the intraluminal imaging device while the movement is stopped and the patient is deep breathing. The processor circuit determines if a shape and/or size of the body lumen changes in the additional intraluminal images. The processor circuit accepts or rejects the candidate intraluminal image based on if the shape and/or size of the body lumen changes. The processor circuit outputs, to the display, a visual representation corresponding to accepting or rejecting the candidate intraluminal image.

摘要： A system includes a processor circuit that receives the IVUS imaging data from the IVUS imaging catheter. The processor circuit identifies calcium based on the IVUS imaging data. The processor circuit determines, based on the identification of the calcium, at least one of: a distance between the calcium and the lumen border; or a density of the calcium relative to the tissue. The processor circuit outputs a screen display to a display in communication with the processor circuit. The screen display includes an IVUS image generated based on the IVUS imaging data; and at least one of: a visual representation of the distance; or a visual representation of the density.
