Robert Buchanan (M.S.,
Radiation Physics) K XRF Laboratory Coordinator.
Robert Buchanan came to the laboratory in October
1997. The KXRF Laboratory Coordinator is responsible for all measurements
required for our studies, both in vivo and experimental, for Quality
Assurance/Quality Control and calibration. The Laboratory Coordinator also
performs spectral analysis, detector operations and maintenance, summary
compilation and statistical computations on human data, database
maintenance and radiation safety compliance. Computer tasks include
creating listing files, taping spectra, software backups and registration,
computer maintenance. In addition, blood spinning, hematocrit measurement,
neurobehavioral testing, vibrotactile and pinch-and-grip strength testing
are required. Other tasks performed occasionally in conjunction with human
testing are subject recruitment and schedule coordination. There is a
large responsibility for the execution and statistical analysis of
experimental data from development and improvement of the XRF systems, to
which Robert contributed his experience in the design of
such experiments. He also assisted in the execution and analysis of
experiments to set up, develop, improve, calibrate and validate LXRF
measurements of lead in bone. And lastly, he wrote the experimental
reports, data analysis and any correspondence resulting from these studies
and experiments.Robert took his Master of Science degree at the University
College of London University under the supervision of Robert Speller,
Ph.D., in the Department of Medical Physics & Biomedical Engineering.
His dissertation, "Design & Testing of an X-Ray Fluorescence
Spectrometer for Measuring Low-Energy Attenuation Coefficients of Tissues
and Tissue Substitutes" (1991), reported efforts to perfect a
technique used to generate and utilize fluorescent x-rays to investigate
the properties of different tissue types. He shared research facilities
and activities with colleagues conducting research in various areas of
radiation physics, including bone densitometry and the classification of
gallstones. His previous work experience includes four years as Chief
Medical Physicist supervising a team of three physicists serving two
radiation oncology and several diagnostic radiology departments at the
Ministry of Health in Kingston, Jamaica. |
