Problems solved by technology

[0003] Currently, the dose compensators on the market are mainly flat and square. Due to the particularity of the contour of the scalp, on the one hand, the dose compensators cannot fit the scalp completely, and there will be an air gap between the two, which will affect the dose distribution of radiotherapy. In addition, The square compensator is difficult to fix on the scalp and often slips during treatment, thereby reducing the dose of electron lines received by the scalp during radiotherapy
Due to the above-mentioned problems of traditional dose compensators, the curative effect of radiotherapy for scalp tumors is generally affected

Embodiment Construction

[0011] A scalp dose compensator 1 for radiotherapy, which is a cap-shaped structure made of paraffin or polystyrene material, the thickness of the cap-shaped structure is equal everywhere, the front part covers the eyebrow arch, the back part covers the upper neck, and the two sides Covers to the upper edge of the pinna. The cap-shaped structure can be manufactured with corresponding thickness and diameter according to requirements. According to the patient's clinical needs, choose a scalp dose compensator with an appropriate thickness, and select a scalp dose compensator with an appropriate diameter according to the patient's head circumference. Place the patient in the accelerator therapy position, apply the selected scalp dose compensator, and administer the treatment. The scalp dose compensator was removed after radiotherapy.

[0012] In order to ensure that the scalp dose compensator fits closely with the scalp, so that there is no gap between the dose compensator and t...

Abstract

The invention relates to the field of medical instruments, in particular to a scalp dose compensator for scalp tumor radiotherapy. The scalp dose compensator is cap-shaped and can be tightly applied to the surface of the scalp, so that an air gap between the dose compensator and the scalp is avoided or reduced, and better radiotherapy dose distribution is obtained; the compensator can be fixed tothe scalp in the using process, and the risk that the dose compensator slips in the treatment process is reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, and relates to a scalp dose compensator for scalp tumor radiotherapy. Background technique [0002] Electron beams are most commonly used in radiotherapy for scalp tumors. During radiotherapy, dose compensators need to be placed on the surface of the scalp to increase the scalp dose, otherwise it will lead to insufficient scalp dose. [0003] Currently, the dose compensators on the market are mainly flat and square. Due to the particularity of the contour of the scalp, on the one hand, the dose compensators cannot fit the scalp completely, and there will be an air gap between the two, which will affect the dose distribution of radiotherapy. In addition, The square agent compensator is difficult to fix on the scalp and often slips during treatment, thereby reducing the dose of electron rays received by the scalp during radiotherapy. Due to the above-mentioned problems of traditional dose compensa...
