The transducers/probes

Which transducer to use depends on what structures you wish to visualise

Higher frequencies penetrate less far as there is greater attenuation of the energy (loss of the sound wave due to reflection, scattering, absorption, refraction and diffraction)

Lower frequencies penetrate further

Spacial resolution

identifying small structures in space. High resolution means you can depict different structures in space. The high frequencies mean shorter pulse lengths which mean you can depict objects that sit behind one another with better resolution (quality)

In addition to frequency, we also need to mention the ‘gain’

To see objects side by side you need good lateral resolution, therefore you need a narrower beam of ultrasound. So if you turn down the gain this will narrow your beam width and you will get a better resolution of objects side by side.

FOR UVC POCUS

We recommend 4-12mHz

The 11MC4 for our preterms. Convex probe which runs at 6MHz and range 3.3-11MHz

And our 10C3 for our term infants. Convex probe which runs at 6MHz, range 3.5-9.7
