Open Source Ultrasound system

Project Title

Open Source Ultrasound system

Project Area of Specialization Biomedical EngineeringProject Summary

The technology related to healthcare require a high degree of robustness, reliability, accuracy and precision therefore there is a need of a great deal of open-source hardware and software systems. On the software side there are already multiple open-source software that are used for medical imaging, mainly used for image processing such as filtering and clarity in the visualization. However, the field of open-source hardware for medical area is less developed or currently less documented. In this project we focus on open source hardware setup with low cost reconfigurable electronic devices for ultrasound image that will be equipped with advanced image processing features.

Project Objectives

1. Study currently available software based open source hardware ultrasound system.
2. Develop an open source ultrasound system both in hardware form.
3. Calibrate the developed system jointly with Medical Experts.

Project Implementation Method

In this Ultrasound Kit we will mainly use two electronic modules which are called Ultrasound Imaging Analog Core(UIAC). Transducer Processing Module: It is designed to provide a precise high-voltage pulse, necessary to excite the sensor, while remaining robust enough to be controlled by an Arduino. The Transducer Pulser Module (TPM) requires both a high-voltage source, and a pulser control. These functions used the Recom Power R05-100B DC/DC Regulated Converter with single-output, to generate a stable high-voltage, which level is determined by a potentiometer, and a Supertex HV7360, High Speed Two or Three Level Ultrasound Pulser, to precisely control the pulse level and duration. Analog Processing Module(APM): It is designed to correctly process the raw ultrasound electric signal, while easily exposing all intermediary signals, and exposing a digital output to the user. The Analog Processing Module (APM) uses a single channel ultrasound Time Gain Compensation (TGC) integrated circuit, the Analog Devices AD8331, Ultralow Noise VGA with Preamplifier, which gain can be controlled by an external 0 to 1V track. The amplified signal is fed into a RF envelope detector, the Analog Devices ADL5511, RF envelope and TruPwrrms detector. The envelope is the unbiased with an analog Devices AD8691 Series   Precision     Amplifier, and optimized for the last item, the Analog Devices  AD7274, a 12-bit,3Mps analog to Digital Converters. We will use the two modules, with a simple transducer for the sensor, and a Arduino compatible microcontroller, with an appropriate ADC, and with wireless capabilities.

Benefits of the Project

               There is no available open-source electronic analog system for ultrasound imaging. There are several open source software initiatives or multiple focus ultrasound control systems. This module will help the researchers by providing complete experimental setup for ultrasound imaging with low cost and size will be compact.
