The Section of Radiological Sciences consists of a group of basic scientists under the direction of David Pickens, Ph.D., who provide the quality assurance basis for the high-technology medical imaging modalities within the department and provide clinical translational support for these modalities. In addition to quality assurance support, this group of physicists, biomedical engineers, radiobiologists, and chemists contribute to basic research and teach the principles of medical imaging to residents, medical students, graduate students, and students in the allied health professions.
Ongoing Research Projects Include:
- Development of Methods for Quantitative Cancer Imaging
- CT Radiation Dose Optimization in Pediatric Patients
- Tissue-Specific Coherent-scatter Computed Topography
- Quantitation of Tumor Blood Flow with Microbubble Ultrasound Contrast Agents
- X-Ray Phase Contrast Digital Tomosynthesis
- Radiation Epidemiology
Clinical Translational Projects:
Members of the Division provide clinical translational support for the technical development, implementation, or refinement of clinical imaging procedures derived from research projects in order to foster improved patient care. Such work involves the refinement of research methods so that they can be used clinically in an effective and efficient manner. Other clinical activities include evaluation of radiation dose for patients having various x-ray or nuclear imaging procedures and evaluation of new technologies that could be incorporated into the clinical imaging enterprise.
Clincal Translational Projects in Progress:
- Implementation of magnetic resonance urography pulse sequences and processing techniques
- Implementation of CT bone densitometry methods
- Development of processing methods for magnetic resonance quantification of liver iron
- Patient-specific dose calculations
- Improved dose reduction protocols for CT and radiography
