Provided is a method in which a web client receives a whole slide image (WSI) having an image compression format and a tile size different depending on a digital pathology vendor from a digital pathology server in a streaming manner. The method includes a WSI acquisition operation of acquiring the WSI from the digital pathology server. The WSI acquisition operation includes a normalized tile definition operation of defining a normalized tile having a minimized time cost, a determination operation of comparing a tile with the normalized tile, and a conversion operation of optimizing the tile with the normalized tile.

WSI streaming method

Provided is an image compression method of a digital pathology system. The image compression method is a method of compressing digital slide images having first to nth original plane images (n is a natural number greater than or equal to 2). The image compression method includes selecting a block having an optimal focal point as an optimal block from each set of blocks positioned at identical positions of the first to nth original plane images; forming one plane image as a virtual optimal plane image by combining only the optimal blocks; generating block descriptors for forming the first to nth original plane images based on the virtual optimal plane image; generating first to nth predictive plane images from the virtual optimal plane image such that the first to nth predictive plane images are out of focus and most similar to the first to nth original plane images by using location information for the blocks and the block descriptors; generating first to nth differential plane images, the first differential plane image corresponding to a difference between the first original plane image and the first predictive plane image and the nth differential plane image corresponding to a difference between the nth original plane image and the nth predictive plane image; and compressing the first to nth differential plane images.

Image compression method for digital pathology system

Disclosed is a patient case identity determination method for a digital pathology system, which is performed by a patient case identity determination unit. The patient case identity determination method includes acquiring a digital slide image from a scanner; requesting a laboratory information system (LIS) to send patient/case information including a preprocessing step image that is obtained in a digital slide preprocessing step associated with the digital slide image; receiving the patient/case information including the preprocessing step image from the LIS; comparatively analyzing a pattern of the digital slide image and the preprocessing step image to calculate a synchronization rate and stores the calculated synchronization rate; and providing information about whether the digital slide image is identical to the patient/case information based on the calculated synchronization rate when a client application provides a reading of the digital slide image.
