Abstract
A system and method for planning surgical procedure including a treatment zone setting view presenting at least one slice of a 3D reconstruction generated from CT image data including a target. The treatment zone setting view presenting a treatment zone marker defining a location and a size of a treatment zone and configured to adjust the treatment zone marker in response to a received user input. The system and method further including a volumetric view presenting a 3D volume derived from the 3D reconstruction and a 3D representation of the treatment zone marker relative to structures depicted in the 3D volume.
Core Innovation
The invention relates to a system for planning a treatment procedure using a user interface that presents image data of a patient as a three-dimensional (3D) reconstruction. A target selection view enables selection of at least one target anatomical feature from the 3D reconstruction, and a treatment zone setting view presents the 3D reconstruction including the selected target anatomical feature and provides an adjustable treatment zone marker that defines a location and a size of a treatment zone.
The treatment zone setting view enables adjustment of a size of the adjustable treatment zone marker in response to a received user input to the adjustable treatment zone marker. The system also presents, on the image data of the patient, an access route setting view that includes a graphically manipulable trajectory line and a depth marker, where the depth marker is movable within the image data of the patient along the trajectory line and each enables interactive adjustment of an access route to the treatment zone.
The access route setting view presents a target marker indicating a position of the target anatomical feature and an entry route marker extending from the target marker with a trajectory line that runs from a first end located at a center of the target marker to a second end configured to be graphically manipulated. The depth marker is positioned on the trajectory line and moved within the image data along the trajectory line to determine a depth measurement relative to a displayed outer tissue boundary of the patient.
Claims Coverage
The partial content includes three independent claims. Across these independent claims, the inventive features center on a planning user interface or non-transitory processor-readable medium that uses image data of a patient to generate and present a 3D reconstruction, define a treatment zone via an adjustable marker with interactive size adjustment, and set an access route via a graphically manipulable trajectory line and a movable depth marker with depth measurement relative to a displayed outer tissue boundary.
3D reconstruction-based target selection in a planning user interface
A user interface presents a target selection view that presents a three-dimensional (3D) reconstruction generated from image data of a patient, where the target selection view enables selection of at least one target anatomical feature from the 3D reconstruction.
Adjustable treatment zone marker with interactive size adjustment
A treatment zone setting view presents the 3D reconstruction including the at least one target anatomical feature and presents an adjustable treatment zone marker defining a location and a size of a treatment zone, where the treatment zone setting view enables adjustment of a size of the adjustable treatment zone marker in response to a received user input to the adjustable treatment zone marker.
Graphically manipulable trajectory line and movable depth marker for access route adjustment
An access route setting view presents, on the image data of the patient, a graphically manipulable trajectory line and a depth marker, wherein the depth marker is movable within the image data of the patient along the trajectory line, and wherein the trajectory line and the depth marker each enable interactive adjustment of an access route to the treatment zone.
Non-transitory medium generating 3D reconstruction and interactive treatment-zone/access-route setting
A non-transitory processor-readable medium stores instructions which cause generating a three-dimensional (3D) reconstruction from received image data of a patient, setting a treatment zone by presenting the 3D reconstruction including a target anatomical feature and presenting an adjustable treatment zone marker defining a location and a size of the treatment zone, adjusting the size of the treatment zone in response to user input to the adjustable treatment zone marker, and presenting a graphically manipulable trajectory line and a depth marker where the depth marker is movable within the image data along the trajectory line to enable interactive adjustment of an access route to the treatment zone.
Target marker, entry route marker trajectory line, and depth measurement relative to an outer tissue boundary
An access route setting view presents on the image data of the patient a target marker indicating a position of at least one target anatomical feature and an entry route marker extending from the target marker with a trajectory line illustrating a pathway, the trajectory line extending from a first end located at a center of the target marker to a second end configured to be graphically manipulated, and a depth marker positioned on the trajectory line and moved within the image data along the trajectory line to determine a depth measurement of the entry route marker relative to a displayed outer tissue boundary of the patient.
Across the independent claims, the core coverage is directed to presenting a 3D reconstruction from patient image data for selecting a target anatomical feature, defining a treatment zone using an adjustable treatment zone marker with interactive size adjustment, and interactively setting an access route using a graphically manipulable trajectory line together with a movable depth marker, including depth measurement relative to a displayed outer tissue boundary.
