Inverse automated treatment planning with and without individual optimization in interstitial permanent prostate brachytherapy with high- and low-activity 125I.

Purpose: To determine whether dose distribution achieved with treatment plans using high- and low-activity (125)I implants differs.

Patients And Methods: Based on intraoperative transrectal ultrasound scans of 71 patients, inverse automated treatment plans (IATP) were performed with 15.5-kBq (0.

The electronic portal imaging system Siemens Beamview Plus versus the conventional verification films CEA-TVS and DuPont COL-7. A critical appraisal of visual image quality.

Aim: The aim of this study was the validation of the visual image quality of electronic portal imaging devices (EPID) and conventional verification films from the point of view of the end-viewers of portal films, the radiotherapists.

Material And Methods: The verification image was represented in two different forms, viz. an electronic portal image employing Siemens Beamview Plus (on a computer monitor) and two different portal films using the conventional verification films CEA-TVS and DuPont CQL-7 (on a negatoscope).
