Summary
Computed Tomography (CT) scanners produce three-dimensional images of vital organs that cannot be obtained by conventional two-dimensional (single projection) x-ray radiographs. However, the radiation exposure is hundreds of times higher than conventional radiography. We will develop the world’s first CT scanner that uses no more radiation than a single conventional x-ray image that will provide four-dimensional reconstructions of a patient’s moving internal organs.
New high resolution radiation dose mapping of special type polymer-gel dosimeters using mini-MRI scanner of high (4.7 Tesla) magnetic field. Gel dosimeters main advantage is dose determination in 3-dimensions. Their main limitation is low spatial-resolution. We propose fabrication of special-type gels and for the first time use the 4.7 Tesla mini-scanner for dose mapping. Increased magnetic field combined with a small aperture for field dissipation will greatly improve spatial resolution down t ....New high resolution radiation dose mapping of special type polymer-gel dosimeters using mini-MRI scanner of high (4.7 Tesla) magnetic field.

We propose fabrication of special-type gels and for the first time use the 4.7 Tesla mini-scanner for dose mapping. Increased magnetic field combined with a small aperture for field dissipation will greatly improve spatial resolution down to micrometers (micro-dosimetry). This new technique will render gel-dosimeters suitable for applications in radiotherapy, industrial and all other radiation fields. Moreover, we will employ new parameter for dose mapping, which is expected to be more sensitive to radiation than the currently used relaxation timesRead moreRead less
Nanoparticle formulations for DNA-targeted radiotherapy and imaging: combinations with chromatin-modifying compounds. This project will develop a new approach for treating and imaging cancer using nanoparticles which target specific cells for cancer therapy and diagnostic imaging. The nanoparticles will be combined with compounds that alter the architecture of DNA to make therapy more effective and to improve the safety of imaging.
