Abstract: The organs motion has been as a matter of challenge for radiation therapy experts; hence the aim of this study was to sense the abdominal motion during breathing and converted into electric signal in order to be mimic and synchronize the organ motion during radiotherapy. The integrated silicon pressure sensor MPX4250 has been constructed and the human breathing pressure has been probed by the sensor and converted into voltage: the generated voltage during inhalation increases from zero (0) volt up to about 5 volts as maximum and the correlation between breathing pressure and the generated volts shows the following equations: y = 0.02x + 0.26 (for inhalation) and: y = - 0.02x + 0.26 for (exhalation). The general breathing mechanism gives a saw tooth curve voltage that could be used to express a synchronized abdominal organs motion during radiotherapy.
