Innovation Solution
A system comprising specially-configured computing devices that obtain and visualize three-dimensional image volumes, allowing health-care professionals to simulate and plan ablation procedures by generating and manipulating a lantern representation of the ablation zone, which can be resized, rotated, and overlaid on original images, enabling precise planning of probe insertion and ablation parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional ablation planning methods are used, then the procedure can be performed with basic imaging, but the accuracy and precision of ablation zone prediction is insufficient
Solution Approach 1:
The patent transitions from traditional two-dimensional imaging to three-dimensional visualization of the ablation zone. By sampling image data along radial lines from the probe tip and organizing it into a 3D coordinate system, the system creates a volumetric representation that provides accurate spatial prediction of the ablation zone, directly improving measurement precision while managing complexity through systematic data organization.
Solution Approach 2:
The system creates a virtual copy or model of the ablation zone by sampling actual image data and reconstructing it in a 3D visualization. This digital twin allows clinicians to predict and evaluate the ablation zone before the actual procedure, improving planning accuracy without requiring additional physical equipment during the procedure itself.
2Manufacturing precision
If detailed image sampling is performed to improve visualization quality, then the accuracy of ablation planning increases, but the processing time and computational resources increase
Solution Approach 1:
The patent divides the image volume into discrete sampling points along radial lines emanating from the probe tip. By segmenting the 3D space into manageable radial segments and sampling image data at specific intervals along these lines, the system achieves precise ablation zone visualization while controlling computational complexity through systematic subsampling rather than processing every voxel.
Solution Approach 2:
The system samples image data at selected radial positions rather than processing the entire image volume. This partial sampling approach provides sufficient precision for ablation planning by focusing computational resources on the critical region around the probe tip, where the ablation zone is located, while reducing overall processing time by excluding unnecessary volumetric data.

AI summary
Systems, devices, and methods obtain an image volume; obtain a description of a surface that includes a shape of the surface, a size of the surface, and a location of the surface in the image volume, sample the image volume on the surface, thereby producing sampled surface-image data; and generate a visualization of the sampled surface-image data.
