Adequate assessment of disease extent is vital for tumour control in the larynx. Xeroradiography using a tomographic technique was investigated. A preliminary study was carried out to assess the optimum technique and exposure. It was also found that the radiation dose to the skin, although just over twice that for film, could be halved by the removal of the secondary radiation grid. Images of 24 patients treated were assessed for soft tissue and bony detail, and it was found that the xerotomograms were beneficial to the radiotherapy planning of the treatment volume of laryngeal and related neck carcinomas.
对疾病范围进行充分评估对于喉癌的肿瘤控制至关重要。对使用断层摄影技术的干板X线照相术进行了研究。开展了一项初步研究以评估最佳技术和曝光量。还发现，尽管皮肤所受辐射剂量仅略高于胶片摄影的两倍，但通过去除二次辐射格栅可将其减半。对24例接受治疗患者的图像进行了软组织和骨质细节评估，发现干板X线断层照片对喉癌及相关颈部癌治疗体积的放射治疗计划有益。
