transducer

Ultrasound probe — converts electrical signal to acoustic waves and back. Types: linear, curved, phased array, matrix, endocavity.

Why it matters to buyers: Probe set drives ultrasound cart value more than the cart itself. A premium cart with tired probes is a worse buy than a mid cart with fresh probes.

Why it matters to engineers: Refurbishment is 60–80% cheaper than replacement and usually returns probes to factory spec.
