Intraluminal ultrasound imaging with automatic and assisted labels and bookmarks

An intraluminal ultrasound imaging method, comprising:

• receiving, at a processor circuit in communication with an intraluminal ultrasound imaging catheter, a plurality of intraluminal ultrasound images obtained by the intraluminal ultrasound imaging catheter during movement of the intraluminal ultrasound imaging catheter within a body lumen of a patient, the body lumen comprising a continuous length formed by a first segment and a different, second segment, wherein, when the movement is in a first direction through the body lumen, the intraluminal ultrasound imaging catheter is located in the first segment before being located in the second segment, and wherein, when the movement is in an opposite, second direction through the body lumen, the intraluminal ultrasound imaging catheter is located in the second segment before being located in the first segment;
• determining an order to provide a first marker and a second marker to be applied to the plurality of intraluminal ultrasound images, wherein the first marker comprises a name of the first segment and the second marker comprises a name of the second segment, wherein the order is determined based on the movement such that:
• the first marker is provided before the second marker in the order when the movement is in the first direction, and
• the second marker is provided before the first marker in the order when the movement is in the second direction;
• providing, based on the order, the first marker or the second marker to be applied to an intraluminal ultrasound image of the plurality of intraluminal ultrasound images;
• and
• outputting, to a display in communication with the processor circuit, a screen display comprising:
• the first marker or the second marker;
• and
• the intraluminal ultrasound image.

An intravascular imaging system, comprising:

• a processor circuit configured for communication with an intravascular imaging catheter, wherein the processor circuit is configured to:
• receive a plurality of intravascular images obtained by the intravascular imaging catheter during movement of the intravascular imaging catheter within vasculature of a patient, the vasculature comprising a continuous length formed by a first segment and a different, second segment, wherein, when the movement is in a first direction through the vasculature, the intravascular imaging catheter is located in the first segment before being located in the second segment, and wherein, when the movement is in an opposite, second direction through the vasculature, the intravascular imaging catheter is located in the second segment before being located in the first segment;
• determine an order to provide a first marker and a second marker to be applied to the plurality of intravascular images, wherein the first marker comprises a name of the first segment and the second marker comprises a name of the second segment, wherein the order is determined based on the movement such that:
• the first marker is provided before the second marker in the order when the movement is in the first direction, and
• the second marker is provided before the first marker in the order when the movement is in the second direction;
• provide, based on the order, the first marker or the second marker to be applied to an intravascular image of the plurality of intravascular images;
• and
• output, to a display in communication with the processor circuit, a screen display comprising:
• the first marker or the second marker;
• and
• the intravascular image.
