Ultrasound-On-Chip With Semiconductor Silicon Chip Array for Transcutaneous Salivary Gland Injections: A Pilot Cadaver Study. [PDF]

Laryngoscope Investig Otolaryngol
Ultrasound (US) is a well‐established imaging modality for evaluating head and neck anatomy. The Butterfly iQ is a handheld ultrasound device that uses a semiconductor silicon chip array (capacitive micromachined ultrasound transducers, CMUT) instead of piezoelectric crystals used by traditional ultrasounds (TUS), but its accuracy has not been ...
