Reason for Recall

In some cases, especially with high dose-per-pulse-rates typical for particle (specifically proton) therapy, measuring errors can result. Individual measurement intervals can be lost that are not visible to the user when there is a high dose-per-pulse rate resulting in a too-low dose being displayed on the monitor. This could result in a radiation over-exposure.
