| Summary: | The main purpose of this project is to design an ultrasonic scanner system which implements the reflection method through a medical ultrasound probe. Due to the high–cost and complex configuration of some of the well–known names in medical devices; such as Philips, and Brauns, the ultrasonic scanner system in this project is aimed to be cost effective and simple. Basically, the ultrasonic scanner system consists of two parts; the transmitter and the receiver. In this project, a PIC microcontroller was used in the transmitter circuit in order to produce a 2 MHz signal to excite the 2.25 MHz ultrasonic transmitter that exists in the medical ultrasound probe that had been selected, whereas the output or the reflected signal was obtain by tapping at the receiver of the medical ultrasound probe and was observed by using a digital oscilloscope. The ultrasonic scanner system was later tested by scanning a papaya. This project was verified by obtaining the reflected signals that resulted from the papaya scanning tests. |
