About This Category

Ultrasound probes (transducers) are the imaging interface of any ultrasound system: they convert electrical pulses into acoustic waves and convert returning echoes back into electrical signals for image reconstruction. Probe selection — including array type (linear, convex, phased array, endocavitary), frequency range, and footprint — is matched to the clinical application (general imaging, vascular, cardiac, OB/GYN, point-of-care, etc.). Compatible probes for a given console are listed by the original manufacturer; replacing or adding a probe typically requires verifying connector type, supported frequency, and software compatibility with the host system.
