title: [Evaluation of the accuracy in radiotherapy for carcinomas of the hypopharynx and larynx].
abstract: Immobility and reproducibility were investigated to evaluate the accuracy in radiotherapy for carcinomas of the hypopharynx and larynx. Based on our comparative study using a semi-conductor detector, a light-cast shell is sufficient to maintain immobility during radiotherapy. In most cases, the range of reproducibility was within 5 mm throughout the course of radiotherapy.
