X-Ray Examination with Minimum X-Ray Dosage
We desire to make an x-ray sensor which is gentle on patients and doctors. NAOMI's multi-CCD detector method makes this possible. NAOMI balances high sensitivity and image resolution with the combination of multiple supersensitive monochrome TST-CCD sensors. This method was only achieved with RF's expertise in CCD technologies. Direct Digital Radiography CCD Imaging Sensor, NAOMI is opening up a new era in the history of radiography.
Both of them are 100kvp 3mAs
The difference is very clear when comparing the images of film and NAOMI. The contrast of the film image is weak because it lacks x-ray amount and has lower sensitivity. On the other hand, NAOMI can capture vivid and clear images because of its high sensitivity.

Super-Sensitive Monochrome TST-CCD Sensor
The signal lines between control components and each CCD sensor are designed with the same length in order for 12 CCDs to receive the command at the same time. Normally, a single CCD makes a pair with a single control component to operate. However on Multi-CCD Detector Method, a single control component can send the command to multiple CCD sensors. By drastically reducing the number of components used it has drastically reducted the production cost. NAOMI provides high image quality and an affordable retail price.
High sensitivity equals to the lower x-ray dose.
A highly sensitive digital camera can capture clear images on a night scene. This is due to the light condensation rate being higher than others. To provide gentle x-ray examinations for doctors and their patients, it needs to reduce the amount of x-ray as much as possible. The mechanism of capturing a photo is fundamentally the same for x-ray and camera. Super-sensitive monochrome TST-CCD sensor decreases the amount of x-rays.
A digital image is made from the smallest dot, "pixel," that is drawn by PC. The grain is also the smallest unit for the CCD sensor which gathers light. How much light can each pixel catch? How effectively can the light transform into electric signals? Those are the key factors for producing the highest quality captured image. If the area of each pixel becomes bigger, the CCD sensor becomes highly sensitive because more light can be captured.
Multi-CCD Detector Method perfectly balances high sensitivity and high resolution.
Multi-CCD Detector Method is the combination of 12 CCD sensors into one unit and then multiple units are structured into a single NAOMI sensor. It is the original technique of RF SYSTEM lab. One CCD sensor has only 270,000 pixels, but structuring multiple units makes x-ray images with high resolution, even with a small amount of x-ray. In the case of 14"x 17" sized sensor, 192 CCD sensors are arrayed, and the image of super high resolution with 51.84 megapixels total can be captured.
