What is the tolerance for localizing laser or ODI indicator at normal clinical distance?

The tolerance for localizing lasers or Optical Distance Indicators (ODI) at normal clinical distance is set at 2 mm. This is based on the need for precision in the delivery of radiation therapy, where accurate localization of the treatment area is essential for ensuring that the prescribed dose is delivered to the target while minimizing exposure to surrounding healthy tissues.

A tolerance of 2 mm ensures that any small variances in laser positioning or indicator alignment do not significantly compromise treatment accuracy. Given that even minor misalignments can lead to unintended radiation exposure or underdosing of the intended target area, the 2 mm tolerance is established as a standard that balances safety and efficacy in clinical practice.

In the context of clinical settings, this measure aligns with industry guidelines and best practices aimed at achieving optimal outcomes in patient care. The importance of maintaining this level of accuracy in the setup process is crucial to the overall success of radiation therapy treatment.
