Some of the best hardware tools for customising your ultrasound devices include function generators, power amplifiers, oscilloscopes,signal monitors and more. This blog explores these tools and how they can be used for customizing your ultrasound settings in detail.
Ultrasound has been playing a major role in lab experiments across various sectors nowadays. These range from material science to biomedical.
For example, in the biomedical field, doctors use ultrasound equipment like High-Intensity Focused Ultrasound Research Systems for tissue ablation (a process used to destroy cancer cells through focused ultrasound waves).
The nature of work performed with ultrasound means that the ultrasound devices used must be calibrated perfectly.
Let’s briefly explain why below, and then talk about the hardware tools that you can use for customizing the ultrasound settings.

Since every experiment is different, not tailoring your ultrasound device can lead to unwanted issues and failures. That’s why calibrating parameters like frequency, amplitude and intensity, pulse, duration, and duty cycle, for example, is important.
For example, in the field of material science, incorrectly calibrated devices can lead to wrong readings.
These wrong readings could affect material science-linked manufacturing processes, and lead to poor quality of materials later on.
You should use the following hardware tools to customize and calibrate your ultrasound device:
These are tools that are used to generate different waveforms to carry out tests and analyze different circuits. The wave forms generated by function generators include sine, triangular, square, pulse, and sawtooth waves.
Each of these waves has the following applications:
You can also use Arbitrary Waveform Generators, which generate custom waveforms, for research and development purposes. These waveform generators are useful for calibrating or customizing programmable ultrasonic research systems.
These components are responsible for increasing or amplifying the signals emitted by ultrasound devices. They also impact transducers because transducers are responsible for generating sound waves to create echoes.
So, a perfectly calibrated amplifier amplifies the electrical signal sent to the transducer. In turn, the transducer effectively generates sound waves to map tissue or material damage.
Oscilloscopes are devices that map changes in electrical signals and reproduce them as graphically. These visualizations help you understand the nature of the electronic signals emitted by the ultrasound device.
So you can use them to determine the performance of your ultrasound devices by mapping changes in their voltage, phase, and frequency.
The frequency changes help you tune the circuits responsible for the ultrasound device’s signal emissions. On the other hand, the phase changes help you synchronize the operations between different components of your ultrasound device.
Signal monitors are devices that reproduce visuals of pulses sent to and reflected from the tissues.
You can use the input from these devices to tune the ultrasound devices accordingly.
Field-Programmable Gate Arrays, or FPAGs, as they are known, are embedded integrated circuits that are used for controlling the various parameters, such as pulse repetition frequency, and the scan patterns.
The pulse repetition frequency determines the depth and clarity of the image generated by the ultrasound device.
The scan patterns determine how the ultrasound transducer scans and studies the tissues or objects under observation.
FPAGs are also useful in modulating the DAS beam forming function, or the Delay-and-Sum beamforming function. This function is used to create clear images by reconstructing the delayed signals together.
The reflected signals are delayed with the help of a time signal and collated together for the final output.
FPGAs can be attached to the circuits responsible for delaying the signals, and create custom delays for clearer images.
High speed Data Interfaces like USB 3.0 are useful for synthetic aperture, plane wave, shear wave elastography, and vector flow imaging. They help transmit the raw data emitted by the transducer to the control display unit, like a PC or a mobile phone.
They support real-time imaging modes like Doppler, including color flow imaging, and B-mode imaging. This allows technicians to study and gain clearer images, by modulating the speed on their portable ultrasound devices, like phones for example.
These refer to an array of ultrasound transducers that can be arranged to precisely modulate the sound waves used to study tissues and other body parts. They are of different types such as:
You can select the right hardware customization tool to tune and calibrate your high-intensity focused ultrasound research systems by following our list of tips below.
You should first determine whether or not the tools you will be selecting match your desired research goals. For example, arbitrary waveform generators can be used to test advanced programmable ultrasound devices.
Your budget is an important factor in choosing the hardware tool. Different tools have different costs, depending on the manufacturer you buy them from.
Apart from that, you should also check whether the tools can be used for calibrating multiple devices at once.
This is a must-check feature. You should be able to integrate the hardware customization tool with your existing testing mechanisms. This will ensure that you don’t have to spend extra money to make integration possible.
Lastly, you should check whether or not you have a nearby repair or service center to offer the required technical support. This will ensure that you do not face any sudden emergencies.
Selecting the right hardware tools to calibrate and customise your ultrasound device will help you improve its functionality. It will also help you get accurate results and prevent unfortunate accidents or errors.
Choose a reputed provider of hardware customization tools to calibrate your ultrasound devices.
