DESCRIPTION OF INTERESTS
My current research objectives involve the development of a multiple scanning beam device for the reduction of scattered radiation in medical radiography. A study of the effect of improved contrast on lesion detectability and the clinical efficacy of theabove scanning beam device is a part of this investigation.
Research involves the development of techniques for the compression of radiographic film transmittance to increase the effective dynamic range of video digitizing systems, photographic print media, or the human observer. Also being currently investigatedare methods for the optimization of the fluoroscopic imaging processes for reduced dose or improved resolution.
Other areas of research include: computer image processing and contrast enhancement; the measurement and reduction of radiation dose to patients and personnel in diagnostic radiology; design of transmission ionization chambers for radiation dose monitoring; characterization of the sensitometric properties of x-ray film;
quality control in diagnostic radiology; development of multiple scanning beam techniques for the reduction of scattered radiation. |
