In this way, an X-ray diagram of an area of interest of the target portion can be obtained by means of only one pass of X-ray scanning, thus preventing multiple X-ray scanning operations, reducing radiation dosage, and simplifying operation. Also disclosed are a method and device for ...
2. Full size digital mammography x-ray imaging. 3. Unique adopt all-solid-state high frequency high voltage generator. This technology has got the PATENT IN THE USA. 4. The safest mammography at high voltage. There is a built-in X-ray ignition coil in host machine, high-voltage power...
X-rays used in medical imaging are usually called soft X-rays because of their low energy level. X-rays are generated inside the X-ray tube as shown inFig. 3which is a vacuum tube that utilizes high voltage to accelerate electrons released from ahot cathode. One type of X-ray, known ...
X-ray diffraction, phenomenon in which the atoms of a crystal, by virtue of their uniform spacing, cause an interference pattern of the waves present in an incident beam of X-rays. The atomic planes of the crystal act on the X-rays in exactly the same ma
However, in X-ray detection, the large quantity of X-ray photons emitted from X-ray machine is not a decay phenomenon in nature, nor does the dark current Idark and the photocurrent under X-ray IX–ray of an X-ray detector. The statistical distribution applicable to photon counting is ...
