TS2000 Service Manual
2.4 General System Work Flow
When a scan is performed, the system sends an electrical current through the
transmitter cable into the hand-held cylinder. The current then flows through
the patient's body and is detected by the scan probe. The current is then
picked up by the scan probe. The current picked up by the scan probe is sent
to the TransScan system that determines the changes in the electrical
impedance. The output is then displayed on system monitor.

2.6 Keyboard and Mouse
2.7 Main System Console
2.8 Computer Base (PC)

The monitor specifications are as follows: 17 inch super VGA, 640 ×
480. The monitor provides the display of the user interface, including
all patient data entries and their resulting T-Scan images.
The keyboard and mouse are standard PC compatible devices that are
used by the TS2000 for system operation and data entry.
The Main System Console is comprised of the Computer Base (PC),
the Processing Module (PM) and the Probe Selection Board (P.S.B.).
The Computer base is a PC with the following configuration:
•
Intel Celleron A300 MHz (or better) with 256 kb EXT.
cache, or equivalent CPU
•
32 MB RAM
•
6.4 GB hard disk, or larger
•
AGP VGA adapter
•
1.44 MB floppy disk (optional)
•
CD-ROM drive
•
ZIP Drive
The PC platform has a medical grade requirement, which refers to the
ability of the PC power supply to meet the AC mains leakage current
requirements.
The Computer Base is the master controller of the system. It is
responsible for the user interface, real-time acquisition, processing and
display of the sensor data sampled by the Processing Module, as well
as database archiving and replay, hard copy, and communications.
