Diagnosis Ultrasound Principles

Blog, Radiology Comments Off 3

The diagnosis ultrasoundis a sound with a frequency going above the hearable level of a human ear, at about 20 kHz (kilohertz). Some animals can hear and acknowledge the ultrasound as they have the higher band of listening. The diagnosis ultrasound has found its usage mostly in medicine, for diagnosing illnesses or for general overview of any part of your body.

What is a diagnosis ultrasound?

The diagnosis ultrasound works by leakage of the ultrasound waves with high frequency through living tissue. The waves are then reflected against this tissue, intensity of which depends of the type of the living tissue the ultrasound is going through. For an example, if you’re performing a diagnosis ultrasound on an area with a lot of bones, on the final print the bones will be represented in their real shape and will be intensively white, meaning that a lot of the ultrasound waves have been completely reflected. Another good example of this principle can be seen when performing a diagnosis ultrasound on a pregnant woman and her baby. The amniotic fluid has low factor for reflecting, so it will actually absorb most of the ultrasound waves, making it appear black on the final print, while the baby will appear obvious in a light gray tone.

Diagnosis ultrasound during pregnancy

The diagnosis ultrasound during pregnancy is performed at different times of pregnancy, for different reasons. In the beginning of your pregnancy, you can perform a diagnosis ultrasound to see if you really are pregnant, what’s the condition of the baby and also, determining the correct age of the baby. In the first trimester you can see are there any anomalies on the baby, further check out the state of developing, diagnose some preventive measures and similar. In the second trimester the diagnosis ultrasound is performed to keep an eye out on baby’s growth, check in detail the anatomy, check the amniotic fluid and similar. In the third and the final trimester you can repeat all the previous checks by performing the diagnosis ultrasound, but can determine the sex of the baby as well.

Future of diagnosis ultrasound

3D and 4D diagnosis ultrasound methods are already in development, these use a computer which processes the data assembled by the ultrasound receivers and conducts a 3D model of the baby or any other object of interest. The fourth dimension practically means time, so a 4D model should provide real time baby monitoring, with real time movements. With these new diagnosis ultrasound methods high quality monitoring can be done to prevent, discover and begin treatment of any anomalies, illnesses or irregularities in time. The diagnosis ultrasound by itself has a few downfalls, as the ultrasound generally isn’t perfect and perhaps it’s needed to find other methods of internal body analysis, which will be less prone to interferences.
