Problems solved by technology

Even if a more advanced fully automatic scanner is used, its time-consuming scanning is difficult to meet the application scenarios that require high real-time performance, such as remote consultation on frozen sections
[0004] 2. Due to the basic optical characteristics, the observation depth of the microscope under high magnification is extremely shallow and easy to lose focus, so frequent autofocus is required during the scanning process
This process is not only time-consuming, but also it is difficult to guarantee the stability of automated operation in the case of thick samples
[0005] 3. Scanning at a high magnification will generate several gigabytes to tens of gigabytes of data. Even if it is transmitted in a high-speed dedicated network, its time-consuming still cannot meet the high real-time requirements of the scene
However, the division of key areas relies on clinical experts with rich diagnostic experience, and general operators and machines cannot yet distinguish

Embodiment 1

[0053] This embodiment relates to an interactive remote labeling method for virtual slices, which relies on traditional microscopes with different magnification functions.

[0054] Include the following steps:

[0055] i. Stitching partial low-magnification images of multiple slices collected by continuous scanning of the digital shooting device into a complete full-width low-magnification image about the slice.

[0056] The digital photographing device can be an electronic eyepiece connected to the microscope, or a digital photographing device such as a mobile phone fixed on the microscope eyepiece through a hanger device.

[0057] As preferred: iffigure 1 As shown, splicing means that after two adjacent images are positioned based on the relative positions of multiple feature point matches, the overlapping parts in the two images are removed and a new image containing all the contents of the previous two images is regenerated. the process of. The two adjacent images refer ...

Embodiment 2

[0079] This embodiment implements an interactive virtual slice remote labeling system based on the method in the first embodiment.

[0080] system includes

[0081] The upper-level end unit and the lower-level end unit are connected through the network, and the lower-level end unit can send a full-width low-magnification image about a complete slice to the upper-level end unit.

[0082] The upper end unit includes an image display module and a target area information input module.

[0083] The image display module is adapted to display image information sent from the lower end unit to the upper end unit.

[0084] The target area information input module is adapted to generate target area information delineated and marked by the user on the full-frame low-magnification image that needs to be further displayed at a high magnification.

[0085] The lower-end unit includes an image acquisition module, an image stitching module, a target area display and labeling module, and a cu...

Abstract

The invention relates to an interactive virtual slice remote marking method and system. The method comprises steps of: splicing local low-magnification images of a slice obtained by continuous scanning with a digital imaging device into a complete full-width low-magnification image about the slice; transmitting the full-width low-magnification image to an upper-level end through a network; and sending target area information of a high-magnification image from the upper-level end to a lower-level end, and coloring a target area on the full-width low-magnification image of the lower-level end; and sending the high-magnification image of the target area acquired by scanning to the upper-level end. By applying the interactive virtual slice remote marking method and system of the present invention, it is possible to ensure remote transmission of high-magnification images of key areas in remote consultation of pathological slices under the premise of the limited network transmission speed. The upper-level clinical expert specifies several key areas requiring high-magnification photographing or scanning after viewing the low-magnification scanned image in the viewing software.

Description

technical field [0001] The invention relates to the fields of digital pathology and remote consultation of pathological slices, and in particular to an interactive remote marking method and system for virtual slices. Background technique [0002] After more than ten years of development, the pathological whole slide imaging technology has basically matured, but there are three technical defects in the application of virtual slice data generated by it in remote consultation: [0003] 1. At high magnifications, full-slice scanning needs to cover thousands of fields of view, which requires a long scanning time. Even if a more advanced fully automatic scanner is used, its time-consuming scanning is difficult to meet the application scenarios that require high real-time performance, such as remote consultation on frozen sections. [0004] 2. Due to the basic optical characteristics, the observation depth of the microscope under high magnification is extremely shallow and easy to...
