This book focuses on thoracic RADIOLOGIA, a versatile, diagnostically accurate, low-cost, noninvasive and non-ionizing imaging technique. Thanks to portable devices, the method can be used to provide quick and accurate diagnoses in emergency settings, during transport, or at the patient s bedside in intensive care units. In addition, as a dynamic examination that allows  real-time  assessment, it can be used to optimize diagnoses, the use of respiratory support equipment, surgical interventions and physiopathological assessments, both in critical patients and those with chronic conditions. Lastly, since it avoids ionizing radiation, thoracic RADIOLOGIA offers a first-line diagnostic tool for thoracic disease assessment in connection with pregnancy, neonatology and pediatrics. Pursuing a practical approach, this book also addresses the technological components that are needed in order to adequately set up the equipment.
