Product Description
Introducing the foreign advanced technology, Angell makes the
products in China. CCD detector technology is one of the main
international technologies in Digital Radiography field. At
present, many big x-ray system manufacturers have began to adopt
CCD detector to make Digital Radiography system. Angell-DR uses
single-reflection CCD which can reach a high spatial resolution of
*7 million pixels (***6****6). It represents the highest spatial
resolution level of DR nowadays. Angell Technology provides high
quality DR products for all the users. Comparisons of Main Digital
Radiography Technologies Detector Technology Advantages
Disadvantages Amorphous silicon flat panel Small size, good image
The electronics in Flat Panel systems are in the direct radiation
beam which is damaging and can cause the electronics to fail;
usually **3 years to be replaced. High purchase and maintenance
cost. Amorphous Selenium flat panel Small size, good image Be
strict to the transportation and application environment; sensitive
to the temperature; the amorphous selenium would form crystal and
dead pixel at high temperature; accumulative x-ray damage leads to
be replaced in two or three years; high purchase cost. Single
reflection CCD No x-ray damage; high quality image; long-term
stability; low purchase and maintenance cost A little bit big
volume Single projectivity CCD High quality image; low purchase
cost Big volume, high diagnostic table; CCD is exposed to the x-ray
directly, easy to be damaged. Features of CCD Technologies 1)
Single CCD, large Array design, pixel matrix of 4K × 4K, *7 million
pixels; spatial resolution 4.6 lp/mm, represents the highest level
in the world nowadays; 2) *7 × *7 inch imaging area, fully meet the
needs of clinical examination; 3) Anti-radiation design of CCD
keeps long-term consistent and reliable image quality, and
significantly lowers the cost. 4) Angell-DR has special BIN2
technology, which can easily change the spatial resolution to **0
million pixels when no need high spatial resolution, such as
physical examination, so as to achieve the image meeting the
clinical requirements at low does. 5) With independent intellectual
property rights, Angell developed an image acquisition and
processing software of DR, which can upgrade automatically.
Complying with DICOM 3.0 standard, it’s easy to process, achieve,
and tele-transmit DR images, and connect with PACS /HIS system. 6)
Bring in advanced image processing technology and output high
quality digital images; such as digital filtering, wavelet
transformation, x-ray light source calibration, temperature, noise
correction techniques. Main Functions: Imaging Part Indicator,
Tissue Equalization, Filter Correction, Grayscale Transform,
