Disclosed is an intraluminal ultrasound imaging system, including a processor circuit in communication with an intraluminal ultrasound imaging catheter, and configured to receive a plurality of intraluminal ultrasound images obtained by the imaging catheter while the imaging catheter is moved through a body lumen of a patient, wherein the plurality of intraluminal ultrasound images comprise axial cross-sectional views of the body lumen. The processor circuit is further configured to generate a stylized graphic of the body lumen based on the plurality of intraluminal ultrasound images, wherein the stylized graphic comprises a longitudinal cross-sectional view of the body lumen, and output, to a display in communication with the processor circuit, a screen display comprising the stylized graphic.

Graphical longitudinal display for intraluminal ultrasound imaging and associated devices, systems, and methods

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.

Intraluminal imaging for reference image frame and target image frame confirmation with deep breathing

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.

Intraluminal image-based vessel diameter determination and associated devices, systems, and methods

Disclosed is an intraluminal ultrasound imaging system, comprising a processor circuit in communication with an intraluminal ultrasound imaging catheter, and configured to receive an intraluminal ultrasound image from the imaging catheter within a body lumen of a patient, the body lumen comprising a plurality of segments. The processor is configured to identify a segment of the plurality of segments where the imaging catheter was located when the image was obtained, and output to a display a stylized figure of the body lumen including the plurality of segments, and an indicator identifying the segment in the stylized figure where the imaging catheter was located when the image was obtained.

Intraluminal ultrasound navigation guidance and associated devices, systems, and methods

An intraluminal ultrasound imaging system includes a processor circuit configured for communication with an intraluminal ultrasound imaging catheter, and is configured to receive an intraluminal ultrasound image obtained by the imaging catheter while the intraluminal ultrasound imaging catheter is positioned within a body lumen of a patient. The processor circuit is further configured to output, to a display in communication with the processor circuit, at least two image type options, receive a user selection of an image type option, select a preset value for at least one image processing parameter based on the image type option, and display the intraluminal ultrasound image according to the image processing parameter.

Disease specific and treatment type specific control of intraluminal ultrasound imaging

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.

Intravascular imaging procedure-specific workflow guidance and associated devices, systems, and methods

Disclosed is an intraluminal ultrasound imaging system, including a processor circuit in communication with an intraluminal ultrasound imaging catheter, and configured to receive a plurality of intraluminal ultrasound images from the imaging catheter during movement of the imaging catheter within a body lumen of a patient, the body lumen comprising a plurality of segments. The processor circuit is further configured to generate a marker to be applied to an intraluminal ultrasound image of the plurality of intraluminal ultrasound images, wherein the marker is generated based on the movement of the intraluminal ultrasound imaging catheter, and wherein the marker is representative of a segment of the plurality of segments, and output to a display the marker and the plurality of intraluminal ultrasound images shown successively.
