Scraper for an applicator to be used in electron radiation therapy and applicator

摘要

A scraper for an applicator to be used in electron radiation therapy includes a three layer arrangement. A first layer of the three layer arrangement faces an incident direction of electrons and consists of a first material of a first atomic number. The first atomic number is smaller than a second atomic number of a second material of a second layer of the three layer arrangement, The second atomic number is smaller than a third atomic number of a third material of a third layer of the three layer arrangement. The third layer faces away from the incident direction of the electrons.

主权项

1. A scraper for an applicator to be used in electron radiation therapy, the scraper comprising:
a three layer arrangement comprising:
a first layer that is an outermost layer facing an incident direction of electrons, the first layer comprising a first material and having a first atomic number;a second layer comprising a second material and having a second atomic number; anda third layer that is an outermost layer facing away from the incident direction of the electrons, the third layer comprising a third material and having a third atomic number, the second layer being disposed between the first layer and the third layer, wherein the first atomic number is smaller than the second atomic number, and the second atomic number is smaller than the third atomic number.
