Automatic Measurement Software Algorithm for Embedded System Used in Portable Ultrasonic Power Meter

The calibration and testing of diagnostic and therapeutic medical ultrasound devices are critical issues in terms of both safety and efficacy [1-3]. Although metrological links have been well established for measurements by radiation force balance (RFB) method, some improprieties have been observed depending on the usage of commercial balances with unknown algorithms [4] such as zero tracing and stability detection. The importance of having a well-functioning RFB system and ultrasound pressure measurement metrology system is clear. Therefore in order to secure the traceability of ultrasound power measurements, a new algorithm at the new instrumentation has been introduced in this study. Preliminary measurement results have been shown that progress will be possible in ultrasound power calibrations. In this paper, information about automatic measurement software algorithm for an embedded system in portable ultrasonic wattmeter which was developed at TUBITAK UME Medical Metrology Research Laboratory will be given.
