Advanced proton imaging in computed tomography.
In recent years the use of hadrons for cancer radiation treatment has grown in importance, and many facilities are currently operational or under construction worldwide. To fully exploit the therapeutic advantages offered by hadron therapy, precise body imaging for accurate beam delivery is decisive. Proton computed tomography (pCT) scanners, currently in their R&D phase, provide the ultimate 3...
متن کاملIssues in Proton Computed Tomography
We report progress on a feasibility study of Proton Computed Tomography and Proton Transmission Radiography for applications in treatment planning and patient positioning for proton radiation therapy. We analyzed data from proton transmission studies through a hollow aluminum cylinder taken with a telescope of silicon detectors with very high spatial and good energy resolution. In addition, we ...
متن کاملBimodal magnetic resonance imaging-computed tomography nanoprobes: A Review
Bimodal imaging combines two imaging modalities in order to benefit from their advantages and compensate the limitations of each modality. This technique could accurately detect diseases for diagnostic purposes. Nanoparticles simultaneously offer diagnostic data via various imaging modalities owing to their unique properties. Moreover, bimodal nanoprobes could be incorporated into theranostic s...
متن کاملDevelopment of Proton Computed Tomography for Applications in Proton Therapy
Determination of the Bragg peak position in proton therapy requires accurate knowledge of the electron density and ratio of effective atomic number and mass (Z/A) of the body tissues traversed. While the Z/A ratio is fairly constant for human tissues, the density of tissues varies significantly. One possibility to obtain accurate electron density information of tissues is to use protons of suff...
متن کاملDesign of Small Animal Computed Tomography Imaging for in vitro and in vivo Studies
Introduction: Mini Computed Tomography (mini-CT) was suggested in biomedical research to investigate tissues and small animals. We present designed and built a mini x-ray computed tomography (mini-CT) for small animals as well as industrial component imaging. Materials and Methods: The system used in this study includes a X-ray tube 20kV to 160kV and a flat pa...
