Description
Technical field
The invention belongs to medical imaging field more particularly to a kind of digitized X-ray machine systems.
Background technology
The medical imaging Processing Algorithm of traditional imaging algorithm utilizes such as Laplacian gold words more on realizing decrease of noise functions
Spatially Fourier's variation is done in frequency layering to tower, and such algorithm will produce a large amount of artificial artifact, also irreversible in noise reduction process
Remove some important picture materials and details.
The imaging algorithm that manufacturer's majority uses independent development is given birth to by the digital medical image documentation equipment of representative of Agfa by foreign countries,
If the MUSICA2 of Agfa uses multiband image enhancement processing technology, spatially the height of frequency is low splits piece image
At 12 different levels (frequency), according to different application fields, different degrees of enhancing, suppression are carried out to each frequency range respectively
System, contrast, the adjusting of window width and window level, the enhancing at edge and treatment of details.Common medical imaging Processing Algorithm utilizes such as more
Spatially Fourier's variation is done in frequency layering to Laplacian pyramids, and the high-frequency region concentrated to details and noise carries out denoising
Enhance with details, low frequency region retain or slightly handles, then inversefouriertransform slice.This method is not intelligent,
Details is inevitably removed when handling high-frequency noise.Most of manufacturers are had purchased due to the limitation of technology and fund
It is third party's image processing algorithms of representative as the core of imaging software using U.S. Context Vision.Though such combination
Complete imaging system can so be formed in a short time, but due to hardware and design difference, experimental data is limited etc., and reasons, processing are calculated
Method can only carry out limited image procossing in the case where passively obtaining data, be difficult to obtain best effective on being ultimately imaged effect
Fruit.Including GE, Carestream medical treatment medical giant inside, due to medical treatment, educational resource and the traditional factor of scientific research, research and development production
The phenomenon that product and characteristic Occidentalize is serious.The rarer clinic or experiment for asian population of product.Asian population and occidentals
Group is in fitness, and body structure, body shape, which has, generally to be distinguished, from the recommended value of film making parameter to Image Processing parameter
Setting has error.
Traditional PACS system (Picture Archiving and Communication Systems, image archiving and
Communication system) data storage as medical image and administrative center, at present application also compare limitation, and application direction also has very extensively
Room for promotion.With the establishments of standard such as DICOM3.0, HL7 and the fast development of medical information, large size at home
Hospital internal and between all establish the remote medical consultation with specialists center based on PACS, but the remote medical consultation with specialists centrales of international coverage accordingly
Preceding or blank so that external advanced medical technology and managerial experiences cannot fast and effectively hospital application at home, project
Resource accumulation by the position in industry of declarer and for many years, can be in the exploitation of the remote medical consultation with specialists central platform based on PACS
After line, the resource of domestic and international large hospital is quickly integrated, realizes the foundation of international distance Consultation Center, current routine PACS
System is often directed to hospital doctor, has ignored disease Man's Demands, can not realize patient and medical treatment, medical staff whenever and wherever possible
Exchange and interaction.
