Application of deep inspiration breath-hold technique in radiotherapy

In radiotherapy for thoracic and abdominal tumors, the negative effect of respiratory movement on radiotherapy persist throughout the whole process of radiotherapy. Deep inspiration breath-hold technique (DIBH) is a method of respiratory movement management in radiotherapy, which can reduce the negative effect of respiratory movement upon radiotherapy in the whole process of radiotherapy. Meantime, DIBH technique has its own characteristics and operation requirements compared with other respiratory movement management measures (such as 4D CT, gated technology and tracking, etc.). The aim of this review was to introduce the advantages, disadvantages and the application status of DIBH technique. Key words: Deep inspiration breath-hold; Neoplasm/radiotherapy
