Scope

YY/T 1990-2025 is the English-translated version of 人工智能医疗器械 细胞病理图像辅助分析软件 算法性能测试方法.

YY/T 1990 sets out how to test an AI cytopathology tool before it can be trusted with a slide. It describes the algorithm performance testing methods for software that applies artificial intelligence to the auxiliary analysis of cytopathological images, covering tasks such as segmentation and cell type recognition, and it applies to software that post-processes those images. Software involved in image acquisition, pre-processing or process optimisation is excluded. It builds directly on the YY/T 1833 series for terminology, datasets and data labelling and on YY/T 1858 for lung imaging, so it reads as the cytology member of an established family rather than a standalone text. An informative annex works through an example of test data collection and labelling. For anyone registering digital pathology or cervical screening software in China, this is the method a reviewer will expect the validation report to follow.

This document describes the algorithm performance testing method for cell pathology image-assisted analysis software using artificial intelligence technology. This document applies to auxiliary analysis software that uses artificial intelligence technology to post-process cytopathological images. This document is not applicable to software related to cytopathology image acquisition, preprocessing, and process optimization.

YY/T 1833.1 Quality Requirements and Evaluation of Artificial Intelligence Medical Devices Part

3 Terms and Definitions

The terms and definitions in YY/T 1833.1, YY/T 1833.2-2022, YY/T 1833.3, and YY/T 1858-2022, as well as the following terms and definitions, shall apply. The meaning applies to this document.

3.1 Digital pathology image High-resolution images acquired by combining digital sensing technology with optical magnification devices and scanning in a fully automated microscope or optical magnification system. The digital images can be viewed on a computer monitor.

3.2 stress sample Within the calibration range of a certain algorithm model, samples with extremely large or extremely small feature capacity are used to determine the generalization performance and reliability of the algorithm model. stability.

Note. Examples of stress samples, such as complex cytopathic lesions, heterogeneous lesions, rare data, or pathological images that introduce noise not included in the cytopathology slide. [Source: YY/T 1858-2022, 3.8, with modifications]

4 Algorithm Performance Testing Requirements

4.1 General Rules The algorithm performance testing process follows the requirements of section

4.1 of YY/T 1858-2022, establishing test documentation and providing a clear and standardized test plan; such as... The testing process requires retesting, but the number of retests should be limited (e.g., not exceeding the number of cell classifications performed by the algorithm) to prevent the algorithm from altering the reference standard.
