title: Dose reconstruction of x-ray irradiation of the larynx.
abstract: The authors have determined the dose distribution in the neck for parallel opposed and three field orthovoltage X-ray irradiation techniques of the larynx. LiF:Mg, Ti rods and pellets combined with film densitometry were used. Absorbed dose measured in the region of vocal chords is about 20% lower than that assessed by assuming full backscatter (perpendicular incidence) and by using standard isodose tables.
