Development and implementation of an ultrasonic-RF distance measuring sensor system for X-ray unit

An ultrasonic distance measuring sensor with radio frequency synchronization was developed and tested. It had a measurement range of about 4.5 m. The main application of this project is to measure the distance between the x-ray emitter and a spot on the patient in a surgery setup. The project involves developing a transmitter and receiver circuit for RF signal and combining it with ultrasonic distance measuring system. A micro controller is programmed to calculate the distance. The outcome of the sensor system is better precision and longer distance measuring capability. Knowing the distance helps the physician to control the amount of dose administered to the patient during x-ray exposure and monitor the dose tracking process.
