Ablation Volume Determination via Cross-Sectional Slicing

The patent divides the ablation volume into multiple cross-sectional slices perpendicular to a defined axis. Each slice is analyzed separately to determine its area, and the volumes of all slices are summed to obtain the total ablation volume. This segmentation approach transforms a complex 3D measurement problem into a series of manageable 2D area measurements, significantly improving measurement precision while maintaining systematic complexity at an acceptable level.

The patent introduces a new dimensional approach by defining an axis through the ablation volume and creating cross-sectional slices perpendicular to this axis. This transforms the traditional 1D linear measurements (diameter and height) into a 2D cross-sectional area measurement approach, enabling more accurate volumetric calculation by capturing the true geometry of the ablation lesion in multiple planes.

The patent performs preliminary actions by defining the axis and creating the cross-sectional slice framework before actual volume measurement. This pre-establishment of the measurement geometry allows for consistent and accurate slicing throughout the ablation volume, improving manufacturing precision. The automated nature of this preliminary setup minimizes the time loss, as the framework is established once and then used for systematic volume calculation.

The patent replaces the mechanical assumption of ellipsoidal shape with a computational slicing method. Instead of forcing the ablation volume into a predefined geometric model (ellipsoid), the system uses computational geometry to directly measure the actual cross-sectional areas and sum their volumes. This substitution of mechanical modeling with computational measurement achieves higher accuracy without significant time penalty, as modern computing can rapidly process the slice data.

The patent incorporates imaging feedback to visualize and analyze the cross-sectional slices of the ablation volume. This feedback mechanism allows the system to evaluate the relationship between the ablation lesion and adjacent structures, assess the completeness of ablation, and predict volumes based on applicator configuration. The imaging feedback transforms the system from simple measurement to intelligent evaluation, enhancing adaptability while the automated analysis keeps complexity manageable.

The patent creates a multi-functional system that not only measures ablation volume but also evaluates adjacent structures, assesses ablation completeness, and predicts volumes based on applicator configuration. By integrating these multiple functions into a single cross-sectional slicing framework, the system achieves high adaptability and versatility without proportionally increasing complexity, as the same core methodology serves multiple evaluative purposes.
