Radiation therapy plays a crucial role in cancer treatment, requiring precise positioning of immobilization devices to ensure accurate and effective delivery of radiation beams. However, inadequate storage practices can lead to unhygienic conditions and potentially damage these essential devices. This article will highlight the importance of proper mask storage and provide practical tips to ensure optimal hygiene and longevity.

Reducing mask-related anxiety enhances radiotherapy patients' treatment experience.Each patient's needs and preferences should be carefully considered, and personalized approaches should be employed to ensure the best possible experience throughout their treatment journey.

The rectum is located at the back of the pelvis, in the curve of the sacrum and coccyx. Patients undergoing radiotherapy for rectal cancer are generally treated in a prone position to reduce the volume of normal bowel in the high-dose volume.

Since the heart and lung positions are very close to the irradiation target area, protecting the heart and lung has always been an important consideration in breast radiotherapy. As seen from the anatomic relationship, the lungs are close to the chest wall, the heart is just in front of the left chest wall, and the inner side of the left chest wall is close to the front wall of the heart, with short distance to the left anterior descending coronary artery (LAD). This anatomic structure easily makes the heart and lungs over-irradiated, thus inducing the risk of cardiovascular disease and radiation pneumonia.

Recently, Enzhuo Quan et al. from the Radiation Physics Department at MD Anderson Cancer Center published a study of a postural fixation protocol for stereotactic radiation therapy (SBRT) of spinal tumours in the Journal of Applied Clinical Medical Physics. The researchers selected two commonly used SBRT fixation Solutions, the Klarity SBRT System and the Elekta BodyFIX System, to conduct a comparative study on initial setup accuracy, set-up stability & efficiency, and operational convenience for medical staff.

An easy and economical way to realize MR Sim with the clinic's existing diagnostic MRI. And the key to using a diagnostic MRI as good as enough for MR Sim is to guarantee the same patient position between MR Sim and CT Sim for ideal image fusion and the same position in the treatment delivery process.
