Perforated thermoplastics are preferred primarily due to their ability to reduce the average skin dose during radiation therapy. The perforations in these materials allow for better air flow and improve the overall heat dissipation when the thermoplastic is formed to the patient’s body contours. This improved airflow helps to minimize the buildup of heat, which can occur with non-perforated materials. The reduction in heat buildup can subsequently decrease the likelihood of skin-induced reactions and can also lead to a more uniform and accurate radiation dose being delivered to the target tissue rather than to the skin.

In addition, by allowing for better alignment and stabilization of the patient during treatment, perforated thermoplastics support the precision of treatment delivery, ensuring that the radiation is targeted exactly where it is needed while minimizing exposure to surrounding healthy tissues. Hence, this makes them a crucial option in the practice of medical dosimetry for optimizing patient safety and treatment efficacy.
