1.3 General Description of CellaVision DM1200
CellaVision DM1200 consists of an optic unit consisting of a microscope and
camera (referred to as a slide scanning unit) and a computer system containing the
acquisition and classification software CellaVision DM software. It is important
that slide preparation is performed according to standardized methods (see
Appendix G — Slide Preparation Guidelines).
General Functionality of the System:
• Receives order information from and sends results to the LIS;
• Scans a user-defined area on a slide;
• Locates and presents images of every located cell or object found on the smear;
• Stores images and results in a database;
• Presents an overview image of a user-defined area on a slide.
1.3.1 Peripheral Blood Application
General Functionality
• Presents an image on a screen of every located cell or object;
• Organizes and suggests cell classification (preclassification) for white blood
cells;
• Makes it possible to identify, confirm or modify (reclassification) the suggested
classification of white blood cells;
• Presents and suggests morphological characteristics (precharacterization) in an
overview image of red blood cells;
• Makes it possible to confirm or modify the precharacterization of red blood cell
morphology;
• Presents an overview image and facilitates platelet estimation.
WBC Preclassification
The system preclassifies the following WBC classes: Band neutrophils, Segmented
neutrophils, Eosinophils, Basophils, Lymphocytes, Monocytes, Promyelocytes,
Myelocytes, Metamyelocytes, Blast cells, Lymphocytes variant forms and Plasma
cells.
The system preclassifies the following non-WBCs: Erythroblasts (NRBC), Giant
thrombocytes, Thrombocyte aggregations, Smudge cells and Artefacts. Non-WBCs
are reported as number of cells or objects /100 WBCs.
Unidentified is a class for cells and objects which the system has preclassified with
a low confidence level.
