Product overview

The 5LT is an endocavity wireless ultrasound probe using electronic array scanning, with 128 elements and 32 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.

Frequencies are linear 7.5-10.0 MHz and endocavity 6.0-8.0 MHz, with linear depth adjustable across 20 / 30 / 40 / 55 mm. The endocavity path is short and balances depth against resolution, which suits transvaginal and transrectal examination.

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. Battery life is 2 hours and can be extended indefinitely by wireless charging. The probe measures 336 x 70 x 20 mm and weighs 300 g.
