Par0019 - elastix

Registration Description

inter patient; rigid and B-spline transformation, advanced mean square and normalized correlation metrics

Image data

3D neck CT for radiotherapy planning
Head and neck
18 scans
Spatial resolution in-plane is 1 mm (16 sets) and 0.7 mm (2 sets). Slice thickness 1.5 mm (5 sets), 2.5 mm (11 sets), 3 mm (1 sets) and 5 mm (1 sets).
Variable longitudinal field of view

Comments: Examples of sagittal views. The tumor is shown in red.

Application

Automatic atlas-based segmentation for the tissues relevant in hyperthermia treatment planning of head and neck.

Registration Settings

For parameter files see the Elastix Model Zoo repository on GitHub.

elastix version: 4.5

Before rigid registration images needs to be aligned due to different longitudinal field of view. Standard center of gravity and origin aligment are not always working.
