1. A method for displaying portions of at least one medical image at different transparency levels based on a relative location and proximity to a determined virtual medical device, the method comprising:
- receiving, from a tracking system, first emplacement information with an emplacement of a first medical device;
determining, with one or more processors, a pose of a first virtual medical device based at least in part on the received first emplacement information;
receiving, from the tracking system, second emplacement information associated with an emplacement of a second medical device;
receiving, from the second medical device, at least one medical image corresponding to an imaged area, wherein the imaged area corresponds to an area that is captured by the second medical device when the second medical device acquires the at least one medical image;
determining, with the one or more processors, a pose of the imaged area based at least in part on the received second emplacement information;
determining whether a portion of the first virtual medical device satisfies a location threshold with respect to a particular location of the imaged area based at least in part on the determined pose of the first virtual medical device and the determined pose of the imaged area;
based at least in part on a determination that the portion of the first virtual medical device does not satisfy the location threshold, causing one or more displays to display a portion of the at least one medical image corresponding to the particular location of the imaged area at a first transparency level;
determining whether the portion of the first virtual medical device satisfies a proximity threshold with respect to the particular location of the imaged area based at least in part on the determined pose of the first virtual medical device and the determined pose of the imaged area; and
based at least in part on a determination that the portion of the first virtual medical device satisfies the location threshold and the proximity threshold, causing the one or more displays to display the portion of the at least one medical image corresponding to the particular location at a second transparency level.

Abstract
A system and method for providing image guidance for placement of one or more medical devices at a target location. The system can be used to display portions of a display object, such as a rendered medical image, at different transparency levels. The system can also be used to resolve co-located display objects, such as a co-located image guidance cue and rendered medical image. The system can further be used to adjust a point-of-view location for one or more medical display objects within a virtual 3D space.

23. A system for displaying portions of a medical image at different transparency levels based on a relative location and proximity to a determined virtual medical device, the system comprising:
-
a computer system in communication with one or more displays, the computer system comprising a computer processor and a non-transitory storage medium, wherein the computer system is configured to; receive, from a tracking system, first emplacement information associated with an emplacement of a first medical device; determine a pose of a first virtual medical device based at least in part on the received first emplacement information; receive, from a second medical device, at least one medical image corresponding to an imaged area, wherein the imaged area corresponds to an area that is captured by the second medical device when the second medical device acquires the at least one medical image; determine a pose of the imaged area based at least in part on second emplacement information associated with an emplacement of the second medical device, the second emplacement information received from the tracking system; determine whether a portion of the first virtual medical device satisfies a location threshold based at least in part on the determined pose of the first virtual medical device and the determined pose of the imaged area; determine whether the portion of the first virtual medical device satisfies a proximity threshold based at least in part on the determined pose of the first virtual medical device and the determined pose of the imaged area; and based at least in part on a determination that the portion of the first virtual medical device satisfies the location threshold and the proximity threshold, cause the one or more displays to display a portion of the at least one medical image corresponding to a particular location of the imaged area at a first transparency level, wherein the computer system causes the one or more displays to display the portion of the at least one medical image corresponding to the particular location of the imaged area at a second transparency level based at least in part on a determination that the portion of the first virtual medical device does not satisfy the location threshold.

24. A method for displaying portions of a display object at different transparency levels based on a relative location and proximity to another display object, the method comprising:
-
receiving, with one or more processors, first emplacement information from a tracking system, the first emplacement information associated with an emplacement of a first object; determining, with the one or more processors, a location of a first display object based at least in part on the first emplacement information; determining, with the one or more processors, a location of a second display object based at least in part on second emplacement information received from the tracking system; determining, with the one or more processors, whether at least a portion of the first display object satisfies a location threshold with respect to the second display object based at least in part on the determined location of the first display object and the determined location of the second display object; based at least in part on a determination that the portion of the first display object does not satisfy the location threshold, causing one or more displays to display the portion of the second display object at a first transparency level; determining, with the one or more processors, whether the portion of the first display object satisfies a proximity threshold with respect to the second display object based at least in part on the determined location of the first display object and the determined location of the second display object; and based at least in part on a determination that the portion of the first display object satisfies the proximity threshold and the location threshold, causing the one or more displays to display the portion of the second display object at a second transparency level.
