Summary
Medical image registration aligns images from different sources for better diagnosis and treatment planning. This review focuses on nuclear medicine applications and challenges in choosing optimal registration methods.
Area of Science:
- Medical Imaging
- Radiotherapy
- Nuclear Medicine
Background:
- Increasing interest in automatic medical image registration across modalities.
- Registered images enhance diagnostic information and aid in surgical/radiotherapy planning and monitoring.
- Nuclear medicine specialists face challenges due to extensive and conflicting literature on optimal registration methods.
Purpose of the Study:
- Provide an overview of medical image registration.
- Highlight applications and issues relevant to nuclear medicine.
Main Methods:
- Literature review of medical image registration techniques.
- Focus on methods applicable to nuclear medicine.
Main Results:
- Lack of commercial, validated software presents a barrier to routine implementation.
- Dual-modality instruments are an alternative.
- Conflicting evidence exists regarding optimal registration methods.
Conclusions:
- Medical image registration is crucial for modern medicine, especially nuclear medicine.
- Further research and validated software are needed to overcome implementation barriers.
