Product overview

The 9C is a convex wireless ultrasound probe using an electronic array, with 64 channels. The system is built into the probe itself. Images are sent over the probe's own built-in Wi-Fi to a phone, tablet or Windows computer, so the probe does not depend on whether the room has a Wi-Fi network.

The probe runs at 3.2-5.0 MHz with a scanning depth adjustable across 90, 160, 240 and 305 mm and a scan angle of 60 degrees. The lower frequency penetrates deeper, which suits abdominal, gynaecological, obstetric, urinary, renal and lung examination.

Imaging modes are B, B/M, Color, PDI and PW, with a gain range of 30-105 dB. Gain, focus, pulse inversion harmonics and noise reduction are all adjustable, and both in-plane and out-of-plane needle guidance are supported. The battery is replaceable and two are supplied as standard, each giving 1.5 hours of operation. The probe measures 156 mm x 60 mm x 20 mm and weighs 230 g.
