Which handheld ultrasound fits my specialty?
The probe format decides the exam, not the brand. Convex heads (3.2/5.0 MHz, 90 to 300 mm) cover abdomen, renal and obstetric work. Linear heads (7.5 to 24 MHz, 10 to 100 mm) cover MSK, skin, vascular and thyroid. Phased heads (2.2/3.6 MHz, 90 to 190 mm) cover cardiac and lung. Endocavity heads (6/8 MHz, 149-degree sector, 30 to 120 mm) cover pelvic imaging.
Which single model covers the most specialties?
The D3Ultra, featured on 24 of the 30 specialty pages. It carries a 3.2/5.0 MHz convex head to 300 mm, a 7.5/10 MHz linear head to 100 mm, and a 3.2/5.0 MHz phased head to 300 mm, on one 263 g body.
Do any of these scanners charge a software subscription?
No. Color Doppler, power Doppler, pulsed-wave Doppler, M-mode, on-screen calipers and DICOM export ship with the probe on every model, and no imaging mode sits behind a membership tier.
What frequency do I need for superficial work?
Three linear probes step up: the L14Pro at 10/14 MHz reaching 80 mm, the L20Pro at 16/20 MHz reaching 40 mm, and the L24Pro at 18/24 MHz reaching 25 mm. All three carry 256 elements. Higher frequency buys resolution and costs depth.
Can one probe do both transabdominal and transvaginal scanning?
The D2T does. It pairs a 3.2/5.0 MHz convex head reaching 305 mm with a 6/8 MHz endocavity head running a 149-degree sector at 30 to 120 mm, on one 305 g body.
Is a handheld enough for echo?
The cardiac page runs parasternal, apical and subcostal windows on phased-array handhelds. The CD2 pairs a 2.2/3.6 MHz phased head (80-degree sector, 90 to 190 mm) with a 7.5/10 MHz linear head; the PD2 adds continuous-wave Doppler for high valve velocities.
Which pages cover newborn and small-child scanning?
Neonatology and pediatrics. Both feature the E11, a 103 g micro-convex probe at 8/11 MHz reaching 30 to 80 mm, and the D2LM, which pairs a 10/12 MHz linear head with a 5/7 MHz micro-convex head.
How long does a scanner run on one charge?
It varies by model: the L10H holds 5 hours on 5,600 mAh; the L14Pro, L20Pro and L24Pro hold 4 hours on 4,400 mAh; the D2T, T8 and D3Pro hold 3 hours on 4,200 mAh; the D3Ultra holds 2 hours on 2,800 mAh.
