Product overview

The 8C uses a convex transducer with the host built into the probe, and images travel wirelessly over the probe's own WiFi to a phone, tablet or PC, so no network has to be provided on site.

The frequency is 3.2-5.0 MHz with four depths, 90 / 160 / 240 / 300 mm. That is the deeper end of the convex range, which suits the abdomen, gynaecology, obstetrics, cardiac, urinary tract, kidney and lung.

Imaging runs in full mode - B, B/M, Color, PDI and PW - and both in-plane and out-of-plane needle guidance lines are supported.

Gynaecology and obstetrics	Uterus and adnexa, fetal development and amniotic fluid	Convex configuration with obstetric measurement set
Urinary tract and kidney	Urinary tract and kidney examination, post-void residual volume	Convex low-frequency configuration
Cardiac and lung	Low-frequency imaging of the heart and lungs	Convex low-frequency configuration
Ambulance and bedside	Rapid bedside assessment of internal bleeding, pleural or peritoneal fluid, pneumothorax	Built-in WiFi, no reliance on a site network

Usage and selection notes

Within the convex series, the depth steps of the 8C run deeper than those of the 5C and 6C (90 / 160 / 220 / 305 mm), so the depth the examination needs decides between them.

For contraindications and precautions, refer to the instructions for use. The device must be operated by a licensed physician with the relevant qualifications.
