Description
Technical Field
The invention relates to the technical field of medical image processing, in particular to a medical image browsing method, a client and a system.
Background
Medical images adopt DICOM (digital Imaging and Communication in medicine) as a standard for image storage, transmission and exchange. Medical imaging equipment, such as CT, generates examination images after a patient scan is completed, the examination images are stored in DICOM format, and a physician then opens DICOM image files for review and diagnosis using specialized DICOM viewer software.
Conventional medical image review is performed on an in-hospital image workstation. Generally, a plurality of image workstation computers are configured for a hospital radiology department according to the number of film reading doctors, and each workstation is provided with professional image browsing processing software so that a plurality of doctors can read and diagnose simultaneously. In this mode, the medical images are completely processed at the local workstation, and the performance requirements of the workstation are high. This is due to the characteristics of medical images: firstly, the data volume is large, for example, an image file generated by one PET/CT examination can reach more than 500 MB; secondly, the image processing algorithm is complex, and especially some advanced processing functions such as tumor analysis, curved surface reconstruction and the like have high requirements on system hardware resources (such as GPU, CPU and memory).
In recent years, with the development of cloud technology and the popularization of doctor remote film reading, an image browsing technology based on an internet cloud platform is generated. The principle of the technology is that a cloud server is responsible for storing and processing medical image DICOM files, and a client is connected with the server through the Internet to browse images. The doctor actually sends a page turning instruction to the server for image operation, the server executes the instruction to generate a corresponding picture (the picture is only a picture in a common JPG format, but not an image in a DICOM format) under the doctor's view angle, and the picture is returned to the client and displayed by the client. In this mode, the client no longer needs to operate a large-size DICOM file, and does not need to perform complex processing on the image, and only needs to send the operation of the doctor to the server and display the JPG picture returned after the processing by the server, and one JPG picture is usually only dozens of KB in size. Therefore, this mode has low requirements for client devices, and ordinary desktop or notebook computers can be used normally. In addition, the method supports a large number of doctors to browse images on line at the same time by utilizing the strong computing power and good expandability of the cloud server.
However, the image browsing technology based on the internet cloud platform has some problems. Firstly, the network environment has high requirements, if the network transmission speed is not enough, the transmission time consumption between the server and the client is prolonged, the doctor operates the card, the interface response is slow, and the user experience is deteriorated. Secondly, the method completely depends on the cloud server, the DICOM file needs to be uploaded to the cloud server for processing before the DICOM file can be browsed, even if a client computer is a high-performance workstation, a doctor only needs to perform conventional basic operation on the image and can only wait for the completion of the uploading of the file. In addition, the DICOM file contains personal information of a patient besides image information, and the DICOM file containing sensitive information is uploaded to the cloud, so that potential security risks are faced.
Therefore, a new medical image browsing method is needed.

As an example, the operation process of the local view module and the server view module in the mixed mode is described in detail by taking PET/CT image browsing as an example.
As shown in fig. 1, the window layout is a window layout for browsing PET/CT images commonly used in a hybrid mode, where a sub-window 1 displays a CT cross-sectional image, a sub-window 2 displays a PET cross-sectional image, and a sub-window 3 displays a fusion image, that is, the CT image of the sub-window 1 and the PET image of the sub-window 2 are respectively set to have a transparency of 50% and are displayed together. The sub-window 4 displays a MIP image based on the PET three-dimensional data. The display effect after loading the patient data is shown in fig. 2.
Wherein, the sub-windows 1, 2 and 3 are local views, and only two-dimensional images of the cross sections of the CT and the PET are processed; and 4, a server view, and after all PET data are loaded by the cloud server, three-dimensional reconstruction is carried out to obtain an MIP image. To make the following interaction between child window 1/2/3 and child window 4: interaction one, when child window 1/2/3 turns pages, the position line on the MIP image of child window 4 needs to change position synchronously. And secondly, the MIP image of the sub-window 4 can be quickly positioned by dragging a positioning line through a mouse, and the sub-window 1/2/3 needs to synchronously display the cross-sectional image at the position.
