Abstract
A system and method for planning and performing an interventional procedure based on the spatial relationships between identified points. The system includes a storage device (102) having an image (104) which includes a plurality of targets (107). A spatial determination device (114) is configured to determine distances and/or orientation between each of the targets. The system is configured to compare the distances and generate a warning signal if at least one of the distances is less than a minimum threshold (128). An image generation device (116) is configured to generate a graphical representation for display to the user which shows the spatial information between a selected target with respect to the other targets. A planning device (126) is configured to modify or consolidate targets automatically or based on a user's input in order to more effectively plan or execute an interventional procedure.
Core Innovation
The invention provides a system and method for planning and performing an interventional procedure based on the spatial relationships between identified points, referred to as targets, in medical imaging. The system includes a storage device to hold an image containing multiple targets for the interventional procedure, a spatial determination device to calculate distances and orientations between each target, and a planning device that analyzes these spatial relationships to generate alerts if targets are too close. Additionally, an image generation device creates graphical representations displaying these spatial relationships to aid user understanding.
The problem addressed arises from prior image-guided interventional procedures where numerous biopsy or treatment targets are identified as single points without spatial context, making it difficult for the practitioner to decide which targets to focus on, especially when multiple targets may belong to the same lesion. Previous systems do not facilitate the assessment or consolidation of spatially close targets without losing critical diagnostic or therapeutic information. The invention aims to improve the usefulness of detected target information by providing spatial data about their distribution, enabling more effective planning and execution of interventional procedures.
Claims Coverage
The patent discloses thirteen inventive features across three independent claims regarding a system and method for planning and performing interventional procedures based on spatial relationships between targets.
System for planning and performing an interventional procedure with spatial distance determination
A system comprising a storage device storing an image with multiple targets, a spatial determination device configured to determine distances between each target, a planning device that compares these distances and generates a signal if any distance is below a minimum threshold, and an image generation device producing graphical representations showing distances between a selected target and others.
Inclusion of spatial orientation determination and data recording
The spatial determination device is further configured to determine orientations between targets and record distances and orientations as data structures such as tables for analysis and representation.
Automatic consolidation or modification of targets based on spatial data and device constraints
A planning device capable of automatically consolidating or modifying targets based on distances and orientations, taking into account physical constraints of the interventional device such as achievable biopsy angles, also allowing manual input from a user to adjust targets accordingly.
Graphical representation in multiple formats
An image generation device configured to generate graphical representations including graphs, tables, or three-dimensional images to display spatial relationships among targets for enhanced visualization during planning.
System for repeat interventional procedure with mapping of prior and current targets
A system maintaining an enhanced planning image merging prior biopsy or treatment locations with current target areas, determining distances and orientations between these points, generating graphical representations, and using a planning device to compare distances and generate signals when thresholds are violated, with capabilities for automated or user-directed consolidation or modification.
Method for planning and performing an interventional procedure based on spatial relationships
A method involving obtaining an image with multiple targets, determining distances between the targets, generating a signal if a distance is under a minimum threshold, and generating graphical representations showing distances between a selected target and others, including optionally determining and recording orientations as well.
The independent claims cover a system and method focused on using spatial relationships between identified targets in images to enhance planning and execution of interventional procedures by determining distances and orientations, generating warnings when targets are too close, producing graphical spatial representations, and enabling automatic or manual consolidation or modification of targets considering physical constraints of the interventional device.
Stated Advantages
Improved understanding of target distribution by providing spatial relationships between plurality of identified biopsy or treatment points.
Enhanced planning and execution of interventional procedures by enabling consolidation or modification of targets without losing diagnostic or therapeutic value.
Allows accounting for inaccuracies in navigation or target mapping by visualizing spatial information.
Facilitates minimal biopsy sites, improved monitoring of cancer progression, higher treatment efficacy, and lower morbidity through spatial analysis.
Documented Applications
Planning and performing image-guided interventional procedures including targeted biopsies and localized therapies.
Repeat interventional procedures involving mapping prior biopsy or treatment locations with current target areas for improved visualization and guidance.
Quantitative evaluation of complex biological or mechanical systems using internal evaluation procedures applicable to various organs such as lungs, liver, brain, uterus, gastrointestinal tract, excretory organs, blood vessels, and other solid or tumor tissues.
