Description
Technical Field
The present invention relates to the field of image archiving and communication technologies, and in particular, to a method, a system, a device, and a storage medium for downloading an image file from a client.
Background
The PACS (Pictures Archiving and Communication System) imaging System is an important component of hospital information systems. The diagnostic images are generated by the radiomedical, cardiovascular Imaging and radiodiagnostic equipment, and the diagnostic equipment outputs digitized image data to the outside through a DICOM (Digital Imaging and Communications in Medicine) 3.0 standard interface. These image files are typically stored in a network storage device. When a doctor looks up the image of a patient at a computer end, the doctor needs to download the image file from the network storage device to the computer end, and the image file is displayed on a computer display after being processed by the image.
As medical imaging is becoming an important means of medical diagnosis and the resolution of detection equipment is increasing, medical PACS image data is on a rapid growth trend. Each examination of a patient produces a set of DICOM images, which are typically files of sizes from several hundred KB (kilobytes) to several hundred MB (megabytes), for example: the size of CT (Computed Tomography) images is 500KB, the size of normal radiographic images is several MB to ten-odd MB, and the size of DSA (Digital Subtraction Angiography) images is several hundreds MB. A typical MRI (Magnetic Resonance Imaging) examination produces thousands of image files at a time.
DICOM image read/write performance has long been challenging. In order to improve the performance, various PACS software adopts various optimization measures, and common optimization measures comprise sequential downloading and downloading according to requirements.
(1) And (3) sequential downloading: first, all files of a check are acquired, and then each file is downloaded in sequence. After the first file is downloaded, the first file is immediately displayed on a screen, so that the doctor can see the image as early as possible and then continuously download other files in the background. The method automatically downloads other files in the background when the doctor browses the images, and achieves the effect of hiding downloading delay.
(2) Downloading according to the requirement: the DICOM images generated by one examination are divided into a plurality of sequences, and when the doctor clicks the corresponding sequence, all files of the sequence are downloaded. This achieves a quick response to a doctor clicking a mouse on the interface, but does not achieve the effect of hiding download delays.
Both methods cannot simultaneously realize background downloading hiding delay and preferential downloading of the specified image sequence file.
