1.0 OVERALL DESCRIPTION

Cardia is an echo cardiogram with imaging in the following modes

1.B

2.M

3.Pulse wave Doppler

4.Continious wave Doppler

5.Colour flow Doppler

It supports imaging with the following transducers

1. 3.0 MHz (2 – 4.5 MHz broad band) 2 element annular mechanical probe

 - Image is displayed in a 15” flat screen TFT monitor at 1024 x 768, 32 bit true colour resolution.

 - Power is derived from an external mains socket. In addition it supports battery backup for 6 hrs through built in batteries.

 - Ultrasound scanner has a standard Computer laptop built in which provides display and storage capabilities.

 - Display is foldable type and the laptop computer is detachable
