This summary is machine-generated.

This study reviews Dynamic Data Driven Deformable Non-Rigid Registration (D4NRR), a method that adjusts preoperative brain images for intraoperative brain shift during surgery. It highlights computational advancements in MRI registration over 15 years.

Area of Science:

Neurosurgery
Medical Imaging
Computational Anatomy

Background:

Neurosurgical procedures rely on preoperative medical images for precise tumor and critical structure localization.
Intraoperative brain shift, a deformation of brain tissue during surgery, creates discrepancies between preoperative plans and the actual surgical field.
While intraoperative imaging tracks shifts, it doesn't replace the quality of preoperative data.

Approach:

This paper focuses on the computational aspects of adaptive numerical approximation methods for Dynamic Data Driven Deformable Non-Rigid Registration (D4NRR).
It details the evolution of these registration techniques over the past 15 years.
The review identifies emerging research directions for the computational elements of D4NRR.

Key Points:
