Product overview

The 8S is an ultra-high-frequency linear wireless ultrasound probe using electronic array scanning, with 192 elements and 64 channels. The host is built into the probe, and images travel over its own WiFi to a phone, tablet or Windows PC, so the unit does not depend on the WiFi available on site.

The frequency is 18.0-24.0 MHz with scanning depth adjustable across 10 / 15 / 20 / 25 mm. High frequency gives good resolution, which suits very shallow structures such as the skin and subcutaneous tissue, and fine vascular detail.

Imaging runs in B, B/M, Color, PDI and PW with a gain range of 30-105 dB, and gain, focus, pulse inversion harmonic imaging and noise reduction are adjustable. In-plane needle guidance lines and out-of-plane guidance are supported. The standard battery runs 1.5 hours and the thicker battery version 3 hours, with wireless charging extending either at any point. The probe measures 140 x 55 x 20 mm and weighs 180 g.

Typical applications

The application scenarios on this page describe the device based on its technical data and configuration. The actual scope of application is the one stated in the product registration certificate. Follow your institution's procedures and the instructions for use.

Setting / department	Typical use	Configuration note
Skin and superficial work	Skin and subcutaneous tissue and other superficial structures	Ultra-high frequency, good superficial resolution
Musculoskeletal and vascular	Superficial musculoskeletal structures and fine vascular detail	Shallow penetration, suited to superficial sites
Anaesthetics and pain management	Guidance for superficial nerve and vessel localisation	Ultra-high-frequency linear

Usage and selection notes

This model belongs to the ultra-high-frequency series: high frequency gives good resolution, which suits the skin, subcutaneous tissue, superficial musculoskeletal structures and fine vascular detail. Its frequency is higher than a conventional linear probe and its penetration is shallower, which is what makes it the choice for fine superficial structures; please confirm the selection with our product department.
