What type of materials is preferable for base plate support on the couch top in medical dosimetry?

Carbon fiber materials are preferable for base plate support on the couch top in medical dosimetry primarily due to their unique properties. They possess a high strength-to-weight ratio, which contributes to a robust and sturdy support without adding unnecessary bulk. This quality is essential in a clinical setting where equipment needs to be both stable and lightweight for easy handling.

Additionally, carbon fiber has excellent radiolucency; it does not significantly interfere with the passage of radiation, allowing for more accurate treatment delivery and dosimetry calculations. This is crucial when planning and delivering radiation therapy, as any artifacts or interruptions in the radiation beam can affect treatment outcomes.

Furthermore, carbon fiber is highly durable and resistant to chemical degradation, which is beneficial in maintaining the integrity and longevity of medical equipment in environments where disinfection and maintenance are regular requirements. Thus, its combination of strength, low density, radiolucency, and durability makes carbon fiber the preferred choice for use as base plate support in medical dosimetry applications.
