host module via the FS-bus. This PCB also provides E-module UP-bus and SI-bus
control as well as power supply filtering and regulation. Regulated power forms are
+BV, HV+155V, HV-37V, +/-90V.
1.6 ECG
The ECG module implements stress echo and echocardiogram ultrasound exams.
The ECG output signal is directed through the A56-1 DPPR (Doppler) PCB for
processing. This module is standard equipment for the G60 S, but not for the G50.
1.7 DIMAQ-IP
The DIMAQ-IP shown in Figure 2-1 is a Pentium III based post-processing unit that
employs the Windows 2000 operating system. The DIMAQ-IP acquires and stores
images (NTSC and PAL) for image and clip store, review, archive, print, and post-
processing applications. It support supports cine clips functions and other software
options such as Stress Echo.
Images travel to and from the host module to the DIMAQ-IP as 16-bit color in YBR
422 format over a 800 Mbit per second serial cable. Keyboard, trackball, and
messaging controls travel to and from the host module over a dedicated internal
Ethernet connection. Depending upon the application requirements, the DIMAQ-IP
can send images back to the host module over the serial cable, or send them to the
monitor through a software controlled switch.
The DIMAQ-IP software contains an application interface layer (API). Because this
API operates between the applications (such as Stress-echo, etc.) and the system
software, it is possible to upgrade or replace the DIMAQ-IP software or the system
software individually.
