What is Alice used for in electron therapy?

Alice is primarily utilized in electron therapy for skin dose enhancement. The term "Alice" refers to a specialized device or technique designed to optimize the dose distribution specifically in the treatment of skin lesions or conditions. In electron therapy, achieving a higher dose at the skin surface is essential for effectively treating superficial tumors, which often require maximum exposure for therapeutic efficacy.

By enhancing the skin dose, Alice helps ensure that the prescribed dose reaches the necessary target area while sparing underlying tissues from excessive radiation exposure. This is critical because electron beams are characterized by their rapid dose fall-off with depth. The focus on enhancing the dose at the skin level is especially important for patients with superficial cancers where seeking to maximize therapeutic impact on cancerous cells located close to the skin surface is paramount.

The other options, while relevant to aspects of radiation therapy, do not align with the specific function of Alice in electron therapy, focusing instead on different facets that are not directly related to skin dose enhancement.
