This book is intended to facilitate the testing of dynamic imaging systems to ensure safety of the systems. The aim is to discuss methods and techniques that may be used to commission and perform quality control (QC) measurements of dynamic x-ray imaging systems; the primary function of which is real time imaging to provide visualization of dynamic anatomical and other processes as they occur. Since dynamic imaging equipment is used for a wide range of clinical applications, the report includes a general description of the characteristics and operational aspects to assist the medical physicist with clinical setup and performance evaluation strategies. The automatic close rate control (ADRC) plays a significant role in determining the balance between patient dose and image quality, therefore the function and evaluation of ADRC plays a significant role in determining the balance between patient dose and image quality, therefore the function and evaluation of ADRC devices is discussed extensively. Key Features Discuss methods and techniques that may be used to commission and perform quality control (QC) measurements of dynamic X-ray imaging systems. Includes a general description of the characteristics and operational aspects to assist the medical physicist with clinical setup and performance evaluation strategies. Function and evaluation of ADRC devices is discussed extensively.
