Overview

Key Features

For quality control of CT simulators and treatment planning systems capable of generating digitally reconstructed radiographs Designed for use with spiral CT scanners and may be used with conventional scanners Simplifies quality control for the radiology physicist and radiation oncology physicist Verifies the accuracy of the digitally reconstructed radiograph (DRR) reconstruction for 3D treatment planning systemsDigitally reconstructed radiographs produced from a commercial CT simulator have been evaluated using this phantom
which consists of a 15 cm high-density polystyrene cubic block. Polystyrene was chosen due to the similarities in electron and physical densities between it and water
while its dimensions were chosen as a compromise between the need to design a compact and portable phantom and the desire to represent a typical anatomical scan volume. In this instance
the anatomical volume most representative of the phantom can be considered as the head
the neck and the brain.The phantom contains four test patterns engraved into three of its six faces. The four patterns are designed to measure low and high contrast resolution
modulation transfer function
ray line divergence accuracy
and spatial linearity of the digitally reconstructed radiograph.Various 3D treatment planning systems can also generate DRR. Hence
the quality control of DRR generation needs to be addressed. This versatile phantom provides essential quality control tools for geometrical 3D treatment planning systems and imaging tools for CT-simulation as well
which are capable of generating DRR for portal design."
