12 FAQ

13 1. Pixel Size and Image Quality 1-1. Factors of effecting Image Quality Sensor Sensitivity, Sensor Pixel Size, Screen Resolution, Image Processing SW, X-Ray Quality, Accuracy of Focal Layer, Patient positioning, ect Sensor Structure and Image Quality 1) General Recognition : Small Pixel Size -> Good Sensor -> Good Image??? 2) Structure of Image Sensor Module X-ray -- CsI (transferring X-ray to Visible Light) FOP (FOS) -- Detector The important thing in the sensor design is for increasing the life time of the sensor module and reducing the scattered light

14 2. CCD & CMOS Image Sensor 2-1. Structure CCD Charge Coupled Device Each pixel can transfer its electric charge to one or other of its neighbors. The last pixel converts the accumulated electronic charge so that the chip outputs digital bits. CMOS Complementary Metal Oxide Semiconductor Each pixel has its own charge-to-voltage conversion so that the chip outputs digital bits. Intra oral sensor, CT = CMOS (area sensor) Panoramic X-ray = CCD (liner sensor)

15 Which is better? CCD or CMOS Old-fashioned Issue CCD CMOS Past - Particular Process - High Quality & High Cost - Fit to TDI System (Time Delay Integration) - General Process - Noise Problem - High Quality & Low Cost (By the advance in technology) Now - Fit to Panoramic X-ray - e.g. Canon 12Milion pixels Digital it Camera (No.1 company in digital camera) - e.g. Schick : Intra-Oral Sensor

16 3. Sensor Resolution Line Pair - Unit of sensor resolution : Line Pair Per mm (lp/mm) - Theoretical formula = 1mm / (2 x Pixel Size) - e.g. Pixel Size 25μm : 1000 / (2 x 25) = 20 lp/mm 3-2. Line Phantom Real Measurement by Line Phantom Difference between theoretical ti Line Pair and real Line Pair - The other factors are not perfect : X-ray Scattering, Noise, Image processing, etc. - Manufacturers do not calculate the effect of Pixel Binning on purpose - Have no Standard Method to evaluate Line Pair by using Line Phantom (Under discussion at American Radiology Association)

17 4. Number of bit (Gray scale) and Image Quality 12 bit (2 12 = 4,096 ) data provides 16 times higher image quality than that of 8 bit data(256). A B A B Image quality of A is different from that of B in 12 bit data, But same in 8 bit data

18 5. Wireless Intra Oral Sensor Do you have the wireless intra-oral sensor? 1) Common Technology - The wireless communication is already commercialized - e.g. Mobile, Intra Oral Camera, etc. 2) The Problems & The Issues - Insufficient Power Supply Only few shots on full charge (Charge time is around 3 hours) - Unstable Telecommunication 3) The Failure of Example : Schick

19 6. Life time of Sensor 6-1) Life time (Experimental Data in our R&D Center) - 40,000 times continuative photographing for Panoramic sensor - 70,000 times continuative photographing for AnySensor (on going) 6-2) Term of Guarantee - Guaranteed for 1 year. - In case that customer wants longer terms of guarantee, the price condition could be variable. 6-3) How to operate the sensor for using longer time? - Prevent from the shock. - Sensor is designed to withstand high temperature and sudden changed in temperature. However we strongly recommend to keep our sensor from -5 to 25.
