Abstract

A co-registration system includes a processor circuit that generates and displays a first co-registration reliability indicator based on the status of an x-ray imaging device and a second co-registration reliability indicator based on the speed of an intravascular catheter/guidewire. The processor circuit receives, from the x-ray imaging device, x-ray images of a blood vessel while the intravascular catheter/guidewire moves through the blood vessel. The processor circuit receives, from the catheter/guidewire, intravascular data representative of the blood vessel while the catheter/guidewire moves through the blood vessel. The processor circuit co-registers the intravascular data to an x-ray image received from the x-ray imaging device. The processor circuit also receives a signal representative of an inactive status of the x-ray imaging device during the movement of the catheter/guidewire. The processor circuit then displays the first reliability indicator representative of the x-ray fluoroscopy device status and may indicate that co-registration is not possible. The processor circuit also determines a speed of the catheter/guidewire and displays a second indicator representative of the speed of the catheter/guidewire being too fast for reliable co-registration.

First claim

What is claimed is:

1 . A system, comprising:
a processor circuit configured for communication with an extraluminal imaging device and an intraluminal imaging catheter or guidewire, wherein the processor circuit is configured to:
receive a plurality of intraluminal images obtained by the intraluminal imaging catheter or guidewire during movement of the intraluminal imaging catheter or guidewire within a body lumen of a patient;
receive a signal representative of a status of the extraluminal imaging device during the movement of the intraluminal imaging catheter or guidewire;
generate a screen display comprising:
a first graphical representation based on the plurality of intraluminal images; and
a second graphical representation based on the status of the extraluminal imaging device and a speed of the movement of the intraluminal imaging catheter or guidewire, wherein the first graphical representation and the second graphical representation are positioned proximate to one another; and

output the screen display to a display in communication with the processor circuit,
wherein the second graphical representation is configured to indicate that the plurality of intraluminal images can be co-registered to an extraluminal image in response to:
the status of extraluminal imaging device comprising an active status; and
the speed satisfying a threshold.

2 . The system of claim 1 , wherein the second graphical representation is configured to indicate that the plurality of intraluminal images cannot be co-registered to the extraluminal image in response to the status of extraluminal imaging device comprising an inactive status.

3 . The system of claim 1 , wherein the first graphical representation comprises a longitudinal view of the body lumen.

4 . The system of claim 3 , wherein the longitudinal view of the body lumen comprises a stack of the plurality of intraluminal images.

5 . The system of claim 3 , wherein the second graphical representation is positioned at a border of the longitudinal view.

6 . The system of claim 5 , wherein the second graphical representation comprises a plurality of symbols positioned along the border.

7 . The system of claim 3 , wherein the second graphical representation comprises an overlay on the longitudinal view.

8 . The system of claim 1 , wherein a length of the second graphical representation is representative of at least one of a distance or a time during the movement of the intraluminal imaging catheter or guidewire that corresponds to the status of the extraluminal imaging device.

9 . The system of claim 7 , wherein the second graphical representation comprises the overlay in response to the status of the extraluminal imaging device comprising an inactive status.

10 . The system of claim 1 , wherein the processor circuit is configured to determine the speed.

11 . The system of claim 1 , wherein the second graphical representation is configured to indicate decreased reliability in co-registration of the plurality of intraluminal images to the extraluminal image in response to:
the status of extraluminal imaging device comprising an active status; and the speed not satisfying a threshold.

12 . The system of claim 1 , wherein the second graphical representation is color-coded based on at least one of the status of the extraluminal imaging device or the speed.

13 . The system of claim 1 , wherein the second graphical representation comprises text.

14 . The system of claim 1 , wherein the screen display comprises a plurality of second graphical representations.

15 . A system, comprising:
an intravascular ultrasound (IVUS) or optical coherence tomography (OCT) catheter; and a processor circuit configured for communication with an x-ray imaging device and the IVUS or OCT catheter, wherein the processor circuit is configured to:
receive a plurality of IVUS or OCT images obtained by the IVUS or OCT catheter during a pullback of the IVUS or OCT catheter within a blood vessel of a patient;
receive a signal representative of a status of the x-ray imaging device during the pullback of the IVUS or OCT catheter, wherein the status comprises one of:
an active status in which the x-ray imaging device is obtaining x-ray fluoroscopic images of the pullback; or
an inactive status in which the x-ray imaging device is not obtaining x-ray fluoroscopic images of the pullback;

determine a speed of the movement of the IVUS or OCT catheter;
generate a screen display comprising:
a longitudinal view of the blood vessel based on the plurality of IVUS or OCT images; and
one or more color-coded graphical representations based on at least one of the status of the x-ray imaging device or the speed, wherein the one or more graphical representations are positioned over or adjacent to the longitudinal view, and wherein the one or more color-coded graphical representations comprise at least one of:
an indication that the plurality of IVUS or OCT images cannot be co-registered to an x-ray image;
an indication that the plurality of IVUS or OCT images can be co-registered to the x-ray image; or
an indication of decreased reliability in co-registration of the plurality of IVUS or OCT images to the x-ray image; and

output the screen display to a display in communication with the processor circuit.

16 . The system of claim 1 , further comprising the intraluminal imaging catheter or guidewire.

17 . The system of claim 16 ,
wherein the intraluminal imaging catheter or guidewire comprises an intravascular imaging catheter configured for intravascular ultrasound (IVUS) or optical coherence tomography (OCT), wherein the plurality of intraluminal images comprises a plurality of IVUS images or a plurality of OCT images.

18 . A system, comprising:
a processor circuit configured for communication with an extraluminal imaging device and an intravascular catheter or guidewire, wherein the processor circuit is configured to:
