In vivo dosimetric control for the management of cervical cancer

A detailed study has been carried out on the possibilities of LiF encapsulated powder, for in vivo dosimetry in intracavitary implants by means of the Amersham manual afterloading system. In vivo dosimetry was carried out in 40 patients randomly selected, which were treated as for their clinical stage. The absorbed dose was measured in points of interest placed in the urinary bladder and the rectum by thermoluminescent dosimetry (TLD); the results of these measures were compared with the calculated values, using perpendicular plates and the isodose curves given by Amersham
