Determine the actual optimal radiation dose levels for chest CT. Learn how to efficiently use the dose reduction techniques. Be able to adapt the radiation dose delivered according to the indication and the patient’s morphology. Become familiar with ultra-low dose (ULD) chest CT and be aware of its current and future applications.
