Knowledge point
From sound to image
The creation of an image from sound is done in three steps –
producing a sound wave, receiving echoes, and interpreting those echoes.
Producing a sound wave
A sound wave is typically produced by a piezoelectric transducer encased in a plastic housing. Strong, short electrical pulses from
the ultrasound machine drive the transducer at the desired
frequency. The frequencies can be anywhere between 1 and 18 MHz, though frequencies up to 50–100 megahertz have been used
experimentally in a technique known as biomicroscopy in special
regions, such as the anterior chamber of the eye. Older technology
transducers focused their beam with physical lenses. Newer
technology transducers use digital antenna array techniques to enable the ultrasound machine to change the
direction and depth of focus.
The sound is focused either by the shape of the transducer, a lens
in front of the transducer, or a complex set of control pulses from
the ultrasound scanner, in the (beamforming) technique. This focusing produces an arc-shaped sound wave from
the face of the transducer. The wave travels into the body and
comes into focus at a desired depth.
Materials on the face of the transducer enable the sound to be
transmitted efficiently into the body (often a rubbery coating, a
form of impedance matching). In addition, a water-based gel is placed between the patient's
skin and the probe.
The sound wave is partially reflected from the layers between
different tissues or scattered from smaller structures.
Specifically, sound is reflected anywhere where there are acoustic
impedance changes in the body: e.g. blood cells in blood plasma, small structures in organs, etc. Some of the reflections return
to the transducer.
Receiving the echoes
The return of the sound wave to the transducer results in the same
process as sending the sound wave, except in reverse. The returned
sound wave vibrates the transducer and the transducer turns the
vibrations into electrical pulses that travel to the ultrasonic
scanner where they are processed and transformed into a digital
image.
Forming the image
To make an image, the ultrasound scanner must determine two things
from each received echo:
- How long it took the echo to be received from when the sound was
transmitted.
- How strong the echo was.
Once the ultrasonic scanner determines these two things, it can
locate which pixel in the image to light up and to what intensity.
Transforming the received signal into a digital image may be
explained by using a blank spreadsheet as an analogy. First picture
a long, flat transducer at the top of the sheet. Send pulses down
the 'columns' of the spreadsheet (A, B, C, etc.). Listen at each
column for any return echoes. When an echo is heard, note how long
it took for the echo to return. The longer the wait, the deeper the
row (1,2,3, etc.). The strength of the echo determines the
brightness setting for that cell (white for a strong echo, black
for a weak echo, and varying shades of grey for everything in
between.) When all the echoes are recorded on the sheet, we have a
greyscale image.
Displaying the image
Images from the ultrasound scanner are transferred and displayed
using the DICOM standard. Normally, very little post processing is applied to
ultrasound images.
