General Information

Many cart based or hand held portable ultrasound machines are now available. Readers are encouraged to compare image quality, purchase price and service support before making a purchase.

Examples of compact, portable point-of-care ultrasound machines are the GE LOGIQ e (Wauwatosa, WI), Philips CX50POC (Bothell, WA), SonoSite M-Turbo (Bothell, WA) and Zonare Ultra SP (Mountain View, CA) machines. The Philips HD 11 XE and Zonare Ultra machine are cart-based system.

Most ultrasound machines have the following components in common:

1. A pulser (transmitter) which generates pulsed echo in brief bursts
2. A transducer which converts electrical energy to acoustic pulses and vice versa
3. A receiver which detects, compresses and amplifies signals
    returning to the transducer
4. A display which displays the signal in the brightness B-mode, the motion
    M-mode and the amplitude A-mode
5. A memory which stores still and video images

All 5 machines have the following features:

1. Compound imaging
2. Color flow Doppler
3. Image recording capability (still images and video)
4. Contrast adjustment (gain control)

GE Healthcare's new LOGIQ e is a compact machine with programmable presets and auto-optimization functions. It has an advanced image acquisition technology feature called CrossXBeam™. This spatial compounding technology can capture multiple images from different angles and then combine them into a singular image in real time. This results in enhancement of anatomical margins, reduction of angular dependence and enhancement of contrast through reduction of speckle and noise.
