Module Description

Given a binary label, this module estimates the largest diameter of the label, its largest in-plane perpendicular diameter, and the third diameter that is perpendicular to the plane of the first two.

Usage

Examples, Use Cases & Tutorials

This module was originally designed to calculate the dimensions of tumor, following the RECIST/WHO guidelines.

• Implementation details The module implements the following algorithm for calculating the dimensions of the label. First, the area of the label slice is computed in all the slices of the image that are passing through the label. This is done for the three orthogonal directions of the image. The largest area slice is found. The largest diameter (DA) is estimated by finding the two most distant points on the contour of the label cross-section. The second diameter (DB) is found by finding the two most distant points on the contour that lie on the line perpendicular to the first diameter. The third diameter (DC) is estimated by calculating the two points of intersection between the line perpendicular to the plane formed by DA and DBpassing through the point of their intersection, and the contour of the analyzed label.
