Review and prospect of radiodiagnosis and radiotherapy supervision in the past 16 years / 中国辐射卫生

In 2003, the responsibility of radiation source safety supervision was redivided and transferred from the health department to the environmental protection department. After the promulgation and implementation of the Rule on the Administration of Radiodiagnosis and Radiotherapy in 2006, due to the incorporation of a large number of medical practice supervision rules, the radiation health supervision of medical institutions has evolved into the radiodiagnosis and radiotherapy supervision. In the past 16 years, radiation, occupational health supervision, and medical practice supervision have not been well integrated, and there are many legal problems in radiodiagnosis and radiotherapy supervision. The regulation rules of environmental protection, metrology, and other relevant departments on radiation sources and radiation devices have been constantly changing, resulting in overly complex regulatory requirements on radiodiagnosis and radiotherapy, which increases the burden of medical institutions. This paper reviews the historical evolution and legal system changes of radiodiagnosis and radiotherapy supervision, analyzes the problems and challenges faced by the relevant regulatory departments, and proposes ways to improve the supervision system.

Introduction of a New Skeletal Imaging Instrument: The Low Radiating-Dose EOS System

STUDY DESIGN: Literature review. OBJECTIVE: The aim of this article is to introduce the EOS imaging device, with a focus on spinal and pelvic alignment. SUMMARY OF LITERATURE REVIEW: The EOS imaging device can obtain images of spinal and pelvic alignment with almost no distortion, using a low radiation dose. MATERIALS AND METHODS: We searched for studies related to the use of EOS imaging device for spinal and pelvic alignment. RESULTS: The EOS is not only capable of simultaneously obtaining paired anteroposterior and lateral X-ray images with a low radiation dose, but also can reconstruct the image as if it was acquired in the patient's reference plane, limiting the distortion to the patient's thickness instead of the whole distance between the source and detector. The EOS device also has the advantage of accurately measuring the sagittal alignment of the spine and pelvis and the torsional deformity of the lower limbs, as the subject can be imaged while standing upright in a weight-bearing posture. CONCLUSIONS: EOS is a new diagnostic technique that can detect spinal and pelvic alignment and deformities of the lower limbs under weight-bearing conditions with a low radiation dose.
