With the widespread application of digital pathology in clinical diagnosis, remote consultation, and AI assistance, hospitals are making choices when selectingDigital pathology scannerIt is necessary to comprehensively evaluate performance, compliance, and scalability. Here are five core indicators to help you choose scientifically:
1. Scanning resolution and objective magnification
Clinical diagnosis recommends a 40x objective lens (equivalent to 0.25 μ m/pixel), which can clearly display details of the cell nucleus; Teaching or screening can be done 20 times (0.5 μ m/pixel). Pay attention to distinguishing between "optical resolution" and "interpolation resolution", the former is the true imaging capability.
2. Matching scanning speed and flux
If the daily average number of slices is less than 50, players can enter the machine for dynamic slicing; >It is recommended to choose an automatic slide loader for 100 slides (supporting continuous scanning of 50-300 slides). The scanning time for a single 40x full image should be controlled within 3-6 minutes to avoid accumulation.
3. Image quality and color fidelity
Require support for sRGB/Adobe RGB color space, with automatic white balance and Z-stack focusing function to ensure clear imaging of thick or uneven slides. Check the DICOM or SVS format samples provided by the manufacturer for actual measurement and evaluation.
4. Compliance certification and clinical applicability
The equipment used for clinical diagnosis must be registered with the National Medical Products Administration (NMPA) (formerly CFDA) or have FDA 510 (k)/CE IVDR certification. The research purposes can be relaxed, but if it is to be converted to clinical practice in the future, it needs to be planned in advance.
5. System compatibility and data management
The scanner should support mainstream formats such as DICOM, SVS, NDPI, and seamlessly integrate with hospital LIS, PACS, or digital pathology platforms. Simultaneously evaluate the storage solution - a single 40x image is approximately 1-3GB, and an annual output of 10000 cases requires TB level storage and backup strategies.
In addition, after-sales serviceResponse speed, support from local engineers, and software upgrade policies should also be taken into consideration. Choose a device that can scan quickly, see clearly, connect effectively, and last a long timeThe digital pathology scanner is a crucial step for hospitals to move towards intelligent pathology.
