1. The Superior Structure of NAOMI
-Multi-CCD Detector Method-

3. The Disadvantages of Current Digital Radiography in the Market
・The initial investment is very high.
　（Especially for direct digital radiography, which is priced approx. US$100,000)
・The current x-ray environment must be replaced for the 　　digital radiography system.
・The maintenance expenses are very high. 　　　　　　　(maintenance fee, warranty etc)

7. Advantages of NAOMI -Multi-CCD Detector Method
□　Affordable Price
□　Immediate Retrofit System
There are only USB cable necessary to plug into a computer, and AC adapter to regular outlet. NAOMI can be immediately retrofit into your current x-ray environment.
□　Easy Maintenance
It does not require to replace the whole sensor like other DR systems with amorphous silicon in the current market. NAOMI can be fixed with only the defective parts. This is also one of the main advantages of 192-CCD array.
X-ray films will disappear in next 5 years　＝　The hospitals / clinics will switch to
digital radiography.

8. Increase the Sensitivity Level
Unique Advantages Of NAOMI
Limitless potential and excellent expansivity of unique RF’s CCD array method compared to digital x-ray sensor on flat panel or with 4-CCD systems.
Increase the Sensitivity Level
□　The exposure level becomes 1/3 compared with film.
□　The power supply unit and x-ray generator become very small. Low radiation can not only 　　reduce x-ray dose on human, but also could eliminate the dedicated x-ray room.
SHARP is exclusively working with RF to produce
special monochrome high sensitivity CCD device for medical use.
Intensify the Image Quality Level
□　Reduce the pitch and densify the array of CCDs within one sensor to increase the image 　　　quality based on the specific medical application.
□　By increasing the number of CCD within a sensor, the image quality can be increased. ⇒
It leads to the development of Mammography
Sensor Size Flexibility and Customization □
By increasing or decreasing the number of CCD array, RF can produce the most appropriate sized sensor in each usage □
NAOMI provides the unlimited possibility of digital radiography sensor to many different applications beyond what we anticipate. ⇒
It leads to the development of many different size of sensors for special requirement on demand

9. Superiority of NAOMI toward CR system
RF Co., Ltd.
Who is a competitor?
There is almost no competitors who carry DR system with the quality and affordability in the market, however, CR system may be our competitors with the price.
Superiority of NAOMI toward CR system
□　NAOMI is about the same as CR systems in the current market
□　NAOMI is a DR system, which directly captures the x-ray image in a
computer for immediate display
□　NAOMI requires much less space compared with CR system
