HOME: Highly optimized microscope environment

Abstract

The Highly Optimized Microscope Environment (HOME) is a computerized microscope designed to assist pathologists and cytotechnicians in clinical routine tasks. The prototype system consists of a IBM‐PC compatible computer and a light microscope in which a built‐in highresolution computer display image is superimposed on the optical image of the specimen. Also, a manually operated encoding stage and objective turret encoder are used to provide continuous monitoring of the stage coordinates and microscope magnification to the computer. This allows any position on a slide to be uniquely defined and makes it possible to measure interactively lengths and areas larger than the size of the microscope field. Software, written in the C language and operating under the MS‐DOS/MS‐Windows environment, is controlled by means of a mouse‐driven cursor moving over menu light‐buttons displayed on the microscope image. The HOME microscope workstation is potentially useful in a wide range of applications such as (i) tagging information on particular cells and tissue structures that can thus be accurately located and relocated, (ii) performing morphometric measurement, differential counting, and stereological assessment of biological specimens, and (iii) training and educating laboratory personnel. Finally, HOME will offer in the near future a userfriendly interface for automatic image processing of cells and tissue entities in interactively selected specimen areas.
