In order to understand and quantitatively analyze the physical phenomena and behavior of each component of mammography system during the breast imaging, we simulated mammography imaging using Monte Carlo simulation codes. MCNP4B code was used for our simulation purpose, and we investigated the effect of target material, anode angle, filtration, peak voltage and exposure on the image quality of mammograms. From the simulation results we expect that optimized operation condition of mammography system can be found.

This event-related fMRI study was to further our understanding about how different brain regions could contribute to effective access of specific information related to cognitive process and shows the different response of brain regions involved in recognition of familiar faces compared to unfamiliar faces and repetition effect.

In recent years, there has been keen interest in phosphor materials responding X-ray. Cesium iodide of the materials is a material with a high $\gamma$-ray stopping power due to its relative high density and atomic number. CsI is noted for its high resistance to thermal and mechanical shock due to the absence of a cleavage plane. To design the structure of CsI detector, we analysed the structure with SEM and XRD and measured UV meter.
