Introduction The purpose of this study was to quantify the reduction in patient radiation dose by X-ray imaging technology using image noise reduction and system settings for neuroangiography and to assess its impact on the working habits of the phys

Recently, three-dimensional (3D) rotational x-ray imaging has been combined with navigation technology, enabling direct 3D navigation for minimally invasive image guided interventions. In this study, phantom experiments are used to determine the accu

A two-dimensional (2D) dosimetry system has been designed for position-sensitive dose-measurement applications in modem radiation therapy. The system consists of a scintillating screen (Gd2O2S:Tb), observed by a low-noise CCD camera with a long integ

We have conducted a prospective study to clinically evaluate a new radiation dose observing tool that displays patient’s peak skin dose (PSD) map in real time. The skin dose map (SDM) prototype quantifies the air kerma based on exposure parameters

A two-dimensionally position sensitive dosimetry system has been tested for different dosimetric applications in a radiation therapy facility with a scanning proton beam. The system consists of a scintillating (fluorescent) screen, mounted at the bea

The current clinical standard of organ respiratory imaging, 4D-CT, is fundamentally limited by poor soft-tissue contrast and imaging dose. These limitations are potential barriers to beneficial “4D” radiotherapy methods which optimize the target

Some recently developed beam diagnostic devices for the beam lines of the AGOR cyclotron are reviewed. The range of applications is from low background nuclear physics experiments at “zero degree” to radiation therapy with proton beams. In partic

Current methods for imaging joint motion are limited to either two-dimensional (2D) video fluoroscopy, or to animated motions from a series of static three-dimensional (3D) images. 3D movement patterns can be detected from biplane fluoroscopy images
