Dynamic X-ray (DXR) is a functional imaging technique that uses sequential images obtained by a flat-panel detector (FPD).This article aims to describe the mechanism of DXR and the analysis methods used as well as review the clinical evidence for its use. DXR analyzes dynamic changes on the basis of X-ray translucency and can be used for analysis of diaphragmatic kinetics, ventilation, and lung perfusion. It offers many advantages such as a high temporal resolution and flexibility in body positioning. Many clinical studies have reported the feasibility of DXR and its characteristic findings in pulmonary diseases. DXR may serve as an alternative to pulmonary function tests in patients requiring contact inhibition, including patients with suspected or confirmed coronavirus disease 2019 or other infectious diseases. Thus, DXR has a great potential to play an important role in the clinical setting. Further investigations are needed to utilize DXR more effectively and to establish it as a valuable diagnostic tool.

Objective：We aimed to evaluate the feasibility of our rehabilitation program for abdominally based rehabilitation following autologous breast reconstruction, and investigate the changes in physical function and health-related quality of life in the early postoperative period.Methods：Fifteen patients who underwent breast reconstruction between September 2020 and October 2021 were included in this prospective, observational case series.The program composed of prehabilitation and postoperative home-based exercise until 12 weeks post-surgery. Adherence to home exercise program was surveyed using a self-reported workout check list. At postoperative 4th, 8th, 12th, and 24th weeks, a physio-/occupational therapist assessed the following objectives：i) Range of motion, muscle strength, and disability of upper extremity and trunk, ii) Quality of life using EQ-5D questionnaire, and iii) Patients' daily activities.Results：No adverse events were observed, and all patients completed the program. Overall adherence to daily exercise was 71.1％．Physical function of the upper extremities recovered in 8th postoperative week；however, truncal function, quality of life, and daily activities in 12th postoperative week remained lower than those observed preoperatively. Nevertheless, the program appeared useful for many patients, although some reported difficulty in continuing the exercise after returning to work.Conclusion：Rehabilitation programs directed by physio/occupational therapists may play a potentially advantageous role in facilitating a return to baseline function and quality of life during the early postoperative period.
