Product overview
The SS-5 is an entry-level portable B-mode ultrasound scanner built around a 10-inch flicker-free high-definition display and a 3.5 MHz electronic convex probe. Display modes are B, B/B, 4B, B+M and M, with 8-segment TGC gain control across near field, far field and total gain.
B-mode magnification runs from x0.8 to x2.0 in six steps, and at x1.8 and x2.0 the depth shift key moves the displayed region. M-mode scanning offers eight sweep speeds. Dynamic range is adjustable from 64 to 96 dB on a 256-level greyscale, with variable-aperture, dynamic apodisation and dynamic filtering in the front end, and digital spatio-temporal filtering, edge enhancement, gamma correction, pseudocolour, frame correlation, dot-line correlation and linear interpolation in the back end.
Measurements cover distance, circumference, area, heart rate, gestational age from BPD, GS, CRL, FL and AC, estimated date of delivery and fetal weight. 128 images can be stored permanently and 256 images replayed. Video is output as standard PAL and SVGA, with an optional USB interface, and the probe sockets accept a range of optional linear, small convex and endocavity probes.
