Graphical user interface for catheter positioning and insertion
A method comprises receiving a position of a tip portion of an instrument at a first location within a patient anatomy and determining a three-dimensional distance between the first location and a target location within the patient anatomy. The method further comprises displaying on a display system an image that includes a target location symbol and an instrument tip portion symbol. The method further comprises displaying on the display system a symbol indicating a direction between the position of the tip portion and the target location. As the tip portion of the instrument changes position, the image is displayed so that the instrument tip portion symbol is a frame of reference for the image and the target location symbol moves with respect to the instrument tip portion symbol to represent a new location of the tip portion relative to the target location.
1 . A method, comprising:
receiving a position of a tip portion of an instrument at a first location within a patient anatomy;
determining a three-dimensional distance between the first location and a target location within the patient anatomy;
displaying on a display system an image that includes a target location symbol and an instrument tip portion symbol; and
displaying on the display system a symbol indicating a direction between the position of the tip portion and the target location,
wherein as the tip portion of the instrument changes position, the image is displayed so that the instrument tip portion symbol is a frame of reference for the image and the target location symbol moves with respect to the instrument tip portion symbol to represent a new location of the tip portion relative to the target location.
2 . The method of claim 1 , wherein:
the target location symbol and the instrument tip portion symbol are displayed in a first window of a display of the display system; and
the symbol indicating the direction between the tip portion and the target location is displayed in a second window of the display.
3 . The method of claim 2 , wherein the symbol indicating the direction between the tip portion and the target location includes directional guidance information for directing the tip portion toward the target location.
4 . The method of claim 1 , further comprising displaying a secondary guidance image,
wherein the target location symbol and the instrument tip portion symbol are displayed in a first window of a display of the display system, and
wherein the secondary guidance image is displayed in a second window of the display.
5 . The method of claim 4 , further comprising, based on the position of the tip portion of the instrument relative to the target location, providing an alert in the secondary guidance image that the position of the tip portion should be adjusted.
6 . The method of claim 5 , wherein the alert is provided when the tip portion of the instrument is nearing the target location.
7 . The method of claim 5 , wherein the alert is provided when the tip portion of the instrument has passed the target location.
8 . The method of claim 5 , wherein the alert is provided when the tip portion of the instrument is moving directly toward the target location.
9 . The method of claim 5 , wherein the alert is provided when the tip portion of the instrument is moving away from the target location.
10 . The method of claim 1 , further comprising displaying an insertion distance symbol representing an insertion distance component of the three-dimensional distance, and wherein a size of the insertion distance symbol scales as an insertion distance between the tip portion and the target location changes.
11 . A non-transitory machine-readable media storing instructions that, when run by one or more processors, cause the one or more processors to:
receive a position of a tip portion of an instrument at a first location within a patient anatomy;
determine a three-dimensional distance between the first location and a target location within the patient anatomy;
display on a display system an image that includes a target location symbol and an instrument tip portion symbol; and
display on the display system a symbol indicating a direction between the position of the tip portion and the target location,
wherein as the tip portion of the instrument changes position, the image is displayed so that the instrument tip portion symbol is a frame of reference for the image and the target location symbol moves with respect to the instrument tip portion symbol to represent a new location of the tip portion relative to the target location.
12 . The non-transitory machine-readable media of claim 11 , wherein:
the target location symbol and the instrument tip portion symbol are displayed in a first window of a display of the display system, and
the symbol indicating the direction between the tip portion and the target location is displayed in a second window of the display.
13 . The non-transitory machine-readable media of claim 12 , wherein the symbol indicating the direction between the tip portion and the target location includes directional guidance information for directing the tip portion toward the target location.
14 . The non-transitory machine-readable media of claim 11 , wherein the instructions further cause the one or more processors to display a secondary guidance image,
wherein the target location symbol and the instrument tip portion symbol are displayed in a first window of a display of the display system, and
wherein the secondary guidance image is displayed in a second window of the display.
15 . The non-transitory machine-readable media of claim 14 , wherein the instructions further cause the one or more processors to, based on the position of the tip portion of the instrument relative to the target location, provide an alert in the secondary guidance image that the position of the tip portion should be adjusted.
16 . The non-transitory machine-readable media of claim 15 , wherein the alert is provided when the tip portion of the instrument is nearing the target location.
17 . The non-transitory machine-readable media of claim 15 , wherein the alert is provided when the tip portion of the instrument has passed the target location.
18 . The non-transitory machine-readable media of claim 15 , wherein the alert is provided when the tip portion of the instrument is moving directly toward the target location.
19 . The non-transitory machine-readable media of claim 15 , wherein the alert is provided when the tip portion of the instrument is moving away from the target location.
20 . The non-transitory machine-readable media of claim 11 , wherein the instructions further cause the one or more processors to display an insertion distance symbol representing an insertion distance component of the three-dimensional distance, and wherein a size of the insertion distance symbol scales as an insertion distance between the tip portion and the target location changes.
