What term describes radiation treatments where the total dose is divided into smaller doses delivered more than once a day?

The correct term for radiation treatments where the total dose is divided into smaller doses and delivered multiple times in one day is hyperfractionation. This approach allows for administering a higher total dose over a shorter overall treatment time, potentially increasing the effectiveness of the treatment while minimizing the damage to surrounding healthy tissues. Hyperfractionation can enhance the tumor control probability while reducing the side effects of treatment.

Hypofractionation, on the other hand, refers to delivering fewer doses with a higher dose amount, which is not applicable in this scenario. Continuous treatment and conventional treatment do not specifically indicate the fractionation schedule used, making hyperfractionation the precise term for the practice described in the question.
