Problems solved by technology

Because the cloud public network (10Mbps-100Mbps) and the private network in the hospital (100Mbps-10000Mbps) have a serious disparity in network speed; or the front-end server has low efficiency due to the multi-response processing business during busy hours, it usually happens that doctors cannot read images smoothly Phenomenon, which greatly affects the doctor's reading efficiency

Embodiment 1

[0022] The pre-download method of cloud-stored DICOM images described in this embodiment, such as figure 1 As shown, it includes the use of a pre-download service program as an intermediate program between the cloud service program and the local image management program. The pre-download service program is installed in the front-end server and in the terminal where the local image management program is located. Install the corresponding client, responsible for the communication conversion and scheduling between the cloud service program and the local image management program. The pre-download service program performs the following steps:

[0023] (a) In the pre-download service program, set the time range of the search history check, the execution time of the pre-download task, whether to start multi-threaded pre-download, the maximum number of pre-download checks, and the selection criteria for pre-download files; among them, pre-download tasks The execution time can be set to a...

Embodiment 2

[0033] The pre-download method of cloud-stored DICOM images described in this embodiment, in addition to the features described in Embodiment 1, in order to facilitate management and ensure effective use of local disk space, the pre-download method further includes the steps:

[0034] (g) The pre-download service program will add pre-fetch marks to the images that are pre-downloaded locally, and allow users to set the image storage time to control the time that the images with pre-fetch marks are stored locally. For example, you can set local retention If the time is one month, when one month has passed, the images with prefetch marks will be automatically deleted locally.

[0035] In order to avoid the confusion of the storage location during the storage process and the inconvenience of reading, the image is pre-downloaded to the local through the HTTP(S)GET protocol in the step (f), which means that when the local storage of the hospital, if the original storage disk is still vali...

Abstract

The invention discloses a pre-downloading method of a DICOM image of cloud storage. The method comprises the following steps of: judging which examined images are to be retrieved before a doctor retrieves the images according to a preset strategy, and downloading the examined images to a storage in a hospital in advance. According to the pre-downloading method for DICOM images stored in cloud, theactual retrieval speed is completely equal to that of local retrieval, doctors cannot feel the difference at all, and due to the flexibility and accuracy of strategy configuration, historical relatedexaminations possibly retrieved by doctors can be accurately covered.

Description

Technical field [0001] The invention relates to a medical image transmission method, in particular to a cloud-stored DICOM image pre-download method. Background technique [0002] Due to the importance of medical imaging data in clinical activities, the National Health Commission’s "Detailed Rules for the Implementation of the Regulations on the Management of Medical Institutions" require medical institutions to store medical imaging data for 15 years for outpatients and 30 years for inpatients. Due to the extremely large capacity of medical images, most medical institutions currently store images online for about 1-3 years based on storage cost considerations. Images that exceed the expiration date are generally backed up by optical discs, mobile hard drives, etc., and stored offline. One of the biggest shortcomings of this storage method is that when clinicians need to read the offline images of the patients, they need to manually search them in the CD or mobile hard disk, and ...
