Sonography Vs. Ultrasound Tech: What’s The Difference?

What is the distinction between sonogram and ultrasound? Sonography is basically a kind of medical imaging technique. High-frequency sound waves are delivered in order to produce images of the internal body parts. Talking about ultrasound, it is basically a tool that is mainly used in order to take pictures. There is another term that has an inextricable connection with Sonography and this is called a sonogram.

In short, we can say that

  • An ultrasound is a kind of tool that is primarily used in order to take a picture.
  • A sonogram is basically the image that the ultrasound produces.
  • Talking about Sonography refers to the process where an ultrasound tool is used for diagnostic purposes.

In other words, we can say that if the ultrasound is the technique or process, a sonogram is a final result.


If we specifically talk about Sonography, it is a kind of painless and non-invasive process. High-frequency sound waves are used in this process and these are called ultrasound waves. It produces pictures of blood flow, blood vessels, soft tissues, and organs. These images are extensively used for medical analysis.

There is another thing that is extensively used. Yes, we are referring to x-ray exams. However, after x-ray exams, ultrasound is the most used form of diagnosis. This method basically helps the doctors in order to gain insights.

If we talk about the core characteristics of ultrasound, these are as follows:

  • It is completely safe.
  • Ultrasound is radiation-free
  • Non-invasive
  • Portable
  • Widely accessible
  • Affordable


A sonogram that is also called an ultrasonogram is a kind of visual image that is produced through an ultrasound examination.


Sonography indicates Diagnostic Imaging Technology. Sonography is done by the medical sonographer. A medical sonographer is also called an ultrasound tech. They are experts in Ultrasound Imaging Technology.

How Ultrasound Works

High-frequency sound waves are involved in the case of ultrasounds. These waves are directly beamed into the patient’s body and then, it echoes organs and off tissues. These echoes basically generate electrical signals. Later, these signals are translated using a computer for producing various images regarding organs and tissues.

There are variations in this process. The variations of the Ultrasound method are as follows:

  • Bone Sonography. It is used in order to determine the density of bone.
  • Elastography is basically used in order to differentiate tumors from healthy tissues.
  • Therapeutic ultrasound. This is basically used for breaking up the tissue.
  • High-Intensity Focused ultrasound is also known as HIFU. It has been designed for modifying or destroying abnormal tissues.

By now, you have understood the difference between Sonography and ultrasound.
