Although one-dimensional densitometry has been widely performed for linac dosimetry, it is a time-consuming, labor-intensive procedure. We studied a new densitometry system (DD-System)that consists of a personal computer and common flatbed-type scanner, with regard to its usefulness for daily QC checks in comparison with conventional densitometry. The spatial resolution of the DD-System is very high, and its accuracy of measurements of field size and flatness are equivalent to those of a conventional system at an optical density <2.0. Although the performance of the image scanner limits the maximum optical density of our system, this system can acquire high-resolution two-dimensional dose distributions quickly and easily. In conclusion, the DD-System is very useful for reducing the amount of time and effort required in daily QC activities. We consider this system applicable to the analysis of complicated dose distributions in this era of IMRT.
