The application of diamond to dosimetry is desirable because of its tissue equivalence, chemical inertness and small size, but this has not been commercially viable owing to the non-reproducible response of natural diamond. The chemical vapour deposition (CVD) of diamond permits controlled, reproducible and large-scale production of this material at potentially low cost. An investigation of some clinically relevant features like the depth-dose distribution as well as the absorbed dose profile, obtained using thermoluminescence (TL), is reported for several CVD diamond films. The TL characterisation presented here shows that CVD diamond films should be excellent TL-mode detectors in instances of radiotherapy and in vivo radiation dosimetry.
由于金刚石具有组织等效性、化学惰性和尺寸小的特点，因此将其应用于剂量测定是很理想的，但由于天然金刚石的响应不可重复，所以这在商业上并不可行。金刚石的化学气相沉积（CVD）能够以潜在的低成本对这种材料进行可控、可重复的大规模生产。本文报道了对几种CVD金刚石薄膜的一些临床相关特性的研究，如使用热释光（TL）获得的深度剂量分布以及吸收剂量分布。此处给出的TL特性表明，在放射治疗和体内辐射剂量测定中，CVD金刚石薄膜应是出色的TL模式探测器。
