➡️ LESSON DESCRIPTION:
This lesson focuses on techniques for reducing patient radiation exposure while maintaining diagnostic image quality in CT imaging. Learners will explore how adjusting technical parameters, optimizing patient positioning, and applying dose modulation strategies contribute to safer and more effective scanning practices.

Objectives:
1. Explain how adjusting mA, kVp, pitch, and beam width affects patient radiation dose, and apply these settings to achieve optimal image quality with minimal exposure.
2. Demonstrate proper patient positioning in the CT gantry, including maintaining isocenter alignment and keeping unnecessary objects outside the scan field to reduce radiation dose.
3. Analyze case examples to determine appropriate technical adjustments that balance image quality and patient safety, ensuring adherence to dose optimization principles.
