What is immobilisation devices?
Immobilization device is a tool that is used to ensure the position of the patient is stable and can be maintained, without any movement. Patient is only allowed to breathe normally. The shaping of this device must be able to maintain patient’s position.
Why is immobilisation important in radiation therapy?
The aim of immobilisation in radiotherapy is to secure the patient is in the same position at each treatment fraction. This is required in order to deliver the planned radiation doses accurately.
What is immobilization treatment?

What is immobilisation in radiotherapy?

What does Hypofractionation mean?
Listen to pronunciation. (HY-poh-FRAK-shuh-NAY-shun) A treatment schedule in which the total dose of radiation is divided into large doses and treatments are given once a day or less often.
What is the principle of immobilization?
The immobilization principle is based on the difference in size of enzyme and substrate or product molecules in comparison with membrane pore size. The membrane allows small sized molecules such as substrate/product to diffuse in and out of the membrane while refrains larger- size enzyme molecules within.
What is yeast immobilization?
Yeast immobilization is defined as the physical confinement of intact cells to a region of space with conservation of biological activity. However, these methods have some consequences on the behavior of the yeasts, affecting the final products of the fermentative metabolism.
What is Vaclock?
Vac-Lok™ Cushions create a rigid and secure support around the patient when a vacuum is drawn through a self-sealing quick-release valve. The cushion retains its shape and guarantees stability and reproducibility of the patient’s position for up to six weeks once the air is vacuumed out.
