Capacitive micromachined ultrasonic transducer (CMUT) arrays for medical imaging
Capacitive micromachined ultrasonic transducers (CMUTs) bring the fabrication technology of standard integrated circuits into the field of ultrasound medical imaging. This unique property, combined with the inherent advantages of CMUTs in terms of increased bandwidth and suitability for new imaging modalities and high frequency applications, have indicated these devices as new generation arrays...
متن کاملMicromachined Capacitive Ultrasonic Immersion Transducer for Medical Imaging
Piezoceramics have been the dominant transducer technology in ultrasound medical imaging for several decades. Recent progress in surface micromachined capacitive ultrasonic immersion transducers makes them an alternative transducer technology, especially in highly integrated twodimensional arrays. This paper demonstrates that the surface micromachined capacitive ultrasonic immersion transducer ...
متن کاملCapacitive Micromachined Ultrasonic Transducer Technology for Medical Ultrasound Imaging
Capacitive micromachined ultrasonic transducer (cMUT) technology has been recognized as an attractive alternative to the more traditional piezoelectric transducer technology in medical ultrasound imaging for several years now. There are mainly two reasons for the interest in this technology: Micromachining is derived from the integrated circuit technology and therefore shares the well-known adv...
متن کاملMedical imaging using capacitive micromachined ultrasonic transducer arrays.
We are investigating the use of capacitive micromachined ultrasonic transducers (cMUT's) for use in medical imaging. We propose an ultrasound probe architecture designed to provide volumetric ultrasound imaging from within an endoscope channel. A complete automated experimental system has been implemented for testing the imaging performance of cMUT arrays. This PC-based system includes custom-d...
متن کاملTwo-Dimensional Capacitive Micromachined Ultrasonic Transducer (CMUT) Arrays for a Miniature Integrated Volumetric Ultrasonic Imaging System
We have designed, fabricated, and characterized two-dimensional 16x16-element capacitive micromachined ultrasonic transducer (CMUT) arrays. The CMUT array elements have a 250-μm pitch, and when tested in immersion, have a 5-MHz center frequency and 99% fractional bandwidth. The fabrication process is based on standard silicon micromachining techniques and therefore has the advantages of high yi...
