Several cases of long term radiation sequelae have been reported in patients with lupus erythematosus and systemic sclerosis after breast or chest wall irradiation. To the authors' knowledge, no experience with such complications in patients with mix

Depth dose characteristics of 24-MV beams from a medical linear accelerator at various SSDs have been measured. The dose buildup, percent depth dose (PDD), and output were measured using ionization chambers and a diode detector under full scatter. Su

Tissue compensators made with a high atomic number material are compact and retain the skin-sparing effect of megavoltage beams. In this note, we have described the use of a commercially available vinyl lead as a material for tissue compensators for

For interstitial implants with radioactive Au-198 seeds, the dosimetric calculations usually ignore the finite source size and employ a point source approximation, resulting in a computed isotropic dose distribution. However, the measured radiation f

A rotating beam splitter was designed and fabricated for use in treating tangential breast fields on an AECL Theratron-80 cobalt teletherapy unit. Its dosimetric properties were studied using a 0.6-cm3 Baldwin-Farmer ionization chamber with Keithley

A method of spatially filtering the primary x-ray beam to emphasize the middle and upper frequency structure within a patient is under investigation. In a feasibility study, a copper filter is constructed which complements the low frequency structure
