1 results about "Picture archiving and communication system" patented technology

A picture archiving and communication system (PACS) is a medical imaging technology which provides economical storage and convenient access to images from multiple modalities (source machine types). Electronic images and reports are transmitted digitally via PACS; this eliminates the need to manually file, retrieve, or transport film jackets, the folders used to store and protect X-ray film. The universal format for PACS image storage and transfer is DICOM (Digital Imaging and Communications in Medicine). Non-image data, such as scanned documents, may be incorporated using consumer industry standard formats like PDF (Portable Document Format), once encapsulated in DICOM. A PACS consists of four major components: The imaging modalities such as X-ray plain film (PF), computed tomography (CT) and magnetic resonance imaging (MRI), a secured network for the transmission of patient information, workstations for interpreting and reviewing images, and archives for the storage and retrieval of images and reports. Combined with available and emerging web technology, PACS has the ability to deliver timely and efficient access to images, interpretations, and related data. PACS reduces the physical and time barriers associated with traditional film-based image retrieval, distribution, and display.

The invention provides a medical image data storing method. The method comprises the following steps of storing all the information of original images of a medical image file in an image library file; adopting an SIFT (Scale Invariant Feature Transform) to detect and describe local characteristics; adopting a K mean cluster to build a vocabulary; adopting a weighting vector to express an image; building an sorting index file; accessing to offset of single image data in the image library file to realize random reading and search of the image data . According to a method for processing the image data in a PACS (picture archiving and communication system) on the basis of cloud calculation, the image storing efficiency and the search speed are increased.
