The entire treatment course needs to be completed multiple times, so internal fixation is required to ensure the repeatability of each treatment.

A treatment usually lasts for more than ten minutes, so position fixation is required to ensure the stability of the patient's position during treatment.

Radiation therapy is different from radiation diagnosis. It has high energy and is very destructive. In order to improve the tumor control rate and protect normal tissue as much as possible, we need to increase the position accuracy.

Determine the patient’s treatment position during treatment

Limit patient movement during treatment, improving precision

Reduce daily treatment setup time and reduce patient waiting time before treatment

The position fixator should be selected with good penetration, good comfort, not easy to be damaged, and easy to operate.

Try to be as standardized as possible in clinical operations

When encountering special patients, specific problems should be analyzed in detail

The accuracy of radiotherapy is greatly affected by bladder filling, small intestinal peristalsis, supine and prone positioning, and urine-holding training and appropriate body position selection are required.

There is a lot of pelvic sweat secretion, and the marking line is easily blurred. Pay attention to protection.
