Thanks for riding this wave with me. As you can see, transducers come in a variety of shapes and sizes. Choosing the correct probe is key to the performance of your ultrasound machine and to the quality of your image displayed.

In October 1953, Dr. Inge Edler and Dr. Carl Hellmuth Hertz of Lund University in Sweden took the first images of movements of the heart with ultrasound waves using the material testing system from Siemens. The new method, today known as echocardiography, became an essential part of cardiac diagnosis.

With a mechanical transducer, the PZT crystal is physically moved to create an image.

1. Linear - active elements are arranged in a straight line

2. Annular- elements are arranged as circular rings with a common center

3. Convex- active elements are arranged in a bowed or arched line. The transducer may also be called a curved, or curvilinear array.

What's an ultrasound transducer and how does it work 

# data[].attributes.body
A transducer is any device that converts one form of energy into another. They are also known as probes.

Ultrasound Transducers perform (2) main functions:

1). During transmission, electrical energy from the u/s system is converted into sound.

2).During reception, the reflected sound pulse is converted into electricity.

There are 6 main types of transducers

1. Mechanical

2. Linear Phased Arrays

3. Annular Phased Arrays

4. Linear Sequential Arrays

5. Convex/Curved/Curvilinear Arrays

6. Vector Arrays

Throughout these slides, I will be discussing what each transducer is and what roles they play in ultrasound. Please follow along to find out more interesting facts "all about ultrasound probes".

Ultrasound PROBE Indicator (Orientation Marker) Position

The “probe indicator” on the ultrasound probe can be identified as an orientation marker (ridge, indentation, groove, or nub) on one side of the probe. This corresponds to the indicator or orientation marker on the ultrasound image.

# data[].attributes.body
Almost like holding a pencil, you want to make sure your indicator is at the top (longitudinally, facing the head of patient) or towards the u/s machine(transversely).

The first therapeutic ultrasound devices, such as the SONOSTAT, were created starting in 1947. From 1968, ultrasound was used not just in physical therapy, but also in urology, where the technique was first used to destroy bladder stones.
