Orthogonal Slice Image Data Sets for Microcalcification Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In breast imaging, particularly during tomosynthesis, radiologists face challenges in efficiently reading and optimizing biopsy processes due to the need to assess multiple slices to accurately locate microcalcification clusters, with existing methods failing to provide reliable spatial extent and sufficient visualization for biopsy targeting.
Innovation Solution
A method for determining orthogonal slice image data sets in tomosynthesis recordings, involving recording, reconstructing, selecting, marking, and determining steps, which allows for improved localization of microcalcifications by generating orthogonal slice images from a tomosynthesis recording, enabling clearer visualization and more accurate biopsy planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a synthetic mammogram (2D image) is used to represent breast tissue, then the overview of the entire breast is improved, but the ability to determine spatial extent and depth distribution of microcalcifications deteriorates
Solution Approach 1:
The patent introduces orthogonal slice image data sets (coronal and sagittal views) as additional dimensions to the standard axial slices. This allows radiologists to view microcalcifications from multiple spatial perspectives simultaneously, transforming the 2D representation limitation into a multi-planar 3D visualization solution that preserves spatial extent information while maintaining overview capability
2Measurement precision
If radiologists scroll through multiple parallel or mutually inclined slices to estimate depth distribution of microcalcifications, then the spatial localization accuracy is improved, but the time required for diagnosis deteriorates
Solution Approach 1:
The patent merges multiple slice image data sets from different planes (axial, coronal, sagittal) into a single integrated display showing orthogonal views simultaneously. This combination allows radiologists to assess depth distribution and spatial extent of microcalcifications across all planes at once, eliminating the need to sequentially scroll through multiple slices while maintaining high localization accuracy
3Measurement precision
If dynamic observation of multiple slices is used to determine depth distribution of microcalcifications, then the estimation accuracy is improved, but the complexity of the workflow deteriorates
Solution Approach 1:
The patent performs preliminary reconstruction of orthogonal slice image data sets (coronal and sagittal planes) from the tomosynthesis recording before the radiologist begins assessment. This pre-processing step creates ready-to-view orthogonal views that immediately display depth distribution information, eliminating the need for dynamic slice scrolling and complex interactive manipulation during diagnosis

AI summary
A method is for determining orthogonal slice image data sets of a tomosynthesis recording of an examination region. In an embodiment, the method includes recording a tomosynthesis recording and reconstructing a plurality of first slice image data sets in a first plane based upon the tomosynthesis recording; selecting a first slice image data set from the plurality of first slice image data sets; marking a microcalcification or a region of interest with a punctiform marking in the first slice image data set selected; and determining, from a second slice image data set in a second plane orthogonal to the first plane, and from a third slice image data set in a third plane orthogonal to the first plane and the second plane, wherein a point of intersection of the first plane, the second plane and the third plane includes the punctiform marking.
