In-room imaging and MR planning

Deformable Image Registration (DIR)

• DIR still not in clinical use • Small study in 5 H&N patients (Speight et al, Leeds, UK) • Using MIRADA RTx (Oxford, UK) software • Propagation of spheres & points to quantify plus visual assessment • Qualitative evaluation sufficient following quantitative commissioning of DIR tool • Inaccuracy in spine, register ROI in that region

• DIR improves use of diagnostic MRI
