[Digital radiography with phosphorus memory: verification of the centering of the patient in high-energy radiotherapy]. / Radiografia digitale con fosfori a memoria: verifica della centratura del paziente nella radioterapia con alte energie.

A digital radiographic system using storage phosphor detectors was employed in order to verify radiotherapy treatments with high energy photon beams (60Co-18 MV X-rays). The wide range linearity of the detectors and also the possibility of digital image post-processing allowed portal films to be obtained with sufficient contrast in all treatment techniques, particularly in the case of mantle fields. The use of digital radiography may become an easy and valuable procedure for therapy verification.
