1.6 System
Overview
The ATLAS Corneal Topography System (CTS) Model 9000 is a diagnostic instrument that
measures the curvature of the cornea and produces a corresponding color topography map.
The map can be viewed on the TFT panel and printed in color. The resultant information can
be used to help diagnose eye pathology and make surgical decisions.
The ATLAS 9000 is an X86 Compatible PC which uses a customized ATLAS software
application running on top of Windows XP embedded OS.
The Optics Head projects a series of light rings onto the cornea of the eye. The rings are
focused on the cornea by positioning the optics head-with the joystick. Once the rings are in
focus, the button on top of the joystick is depressed to capture an image of the eye. The
instrument then determines corneal curvature values by measuring the distance between the
rings. These values are then converted by the software into a topographical map of the
cornea.
1.7 Functional
Description
1.7.1 Base
Module
The following items are major components in the ATLAS 9000 computer assembly. Refer to
Section 7 for identification and location information for each sub component.
Computer Board
The Computer board is a mini-ITX form factor PC motherboard. It uses the Intel Pentium M
processor and runs under Windows XP operating system. The Computer Board is responsible
for the operating tasks on the instrument. In addition to the traditional Motherboard/CPU
detail, its functions also include:
•
Video driver- Hardware necessary to display an image on the internal TFT screen, or
external monitor.
Note -
Separate Circuitry for video capture is no longer needed, as it is handled in
software.
•
External Interface – USB Printers, Flash Drives, Network Interface, Keyboard, Mouse,
External Display, are all negotiated through the Computer Board.
•
HDD / DVD Drive interface – Computer Assy contains both IDE and SATA interface
for internal storage devices.
Figure 1.1 (next page) details the board’s connectivity.
