PURPOSE
A bolus is usually required to ensure radiation dose coverage of extensive superficial tumors of the scalp or skull. Oftentimes, these boluses are challenging to make and are nonreproducible, so an easier method was sought.
METHODS AND MATERIALS
Thermoplastic sheets are widely available in radiation oncology clinics and can serve as bolus. Two template cutouts were designed for anterior and posterior halves to encompass the cranium of children and adults.
RESULTS
The created bolus was imaged using computed tomography, which demonstrated good conformity and minimal air gaps.
CONCLUSIONS
Although making a bolus for treating superficial tumors of the scalp or head and neck is challenging, the presented technique enables thermoplastic to be used as a bolus and is quick, easy, and reproducible.
目的
通常需要使用填充物来确保对头颈部广泛浅表肿瘤的辐射剂量覆盖。通常，这些填充物制作具有挑战性且不可重复，因此寻求一种更简便的方法。
方法和材料
热塑性片材在放射肿瘤学诊所广泛可得，可作为填充物使用。设计了两个模板切口，分别用于儿童和成人颅骨的前半部分和后半部分。
结果
使用计算机断层扫描对制作的填充物进行成像，显示出良好的贴合性和最小的气隙。
结论
尽管制作用于治疗头皮或头颈部浅表肿瘤的填充物具有挑战性，但所提出的技术能够将热塑性材料用作填充物，且快速、简便且可重复。
