Introduction
The 4D CT Cookbook 2.0 is a guide for SOMATOM CT users, focusing on 4D CT imaging in radiation therapy (RT). It addresses the challenge of motion in radiation therapy, which is crucial for precise margins and “mid-vent” dose planning.
Importance of 4D CT
4D CT imaging helps detect and synchronize with respiratory motion, reducing image artifacts and treatment risks. It is essential for cancer care and External Beam Radiation Therapy (EBRT).
Content Overview
The cookbook covers topics such as breathing recording systems, patient selection, acquisition, reconstruction, contouring, and quality assurance for Varian RGSC.
Key Takeaways
Accurate scan parameters and good synchronization between acquisition and the patient’s breathing curve are crucial for high-quality 4D CT datasets. Breathing recording systems, patient selection, and optional breathing training are important factors in reducing artifacts and uncertainties.
