Overview
Scan with clinical flexibility in mobile and point-of-care environments. Dawei Medical offers the DW AI+ series: ultra-portable, cable-free ultrasound probes with integrated AI tools to support rapid, quantitative bedside assessment.

Models

• DW AI+ series — available models: DW-X1S (three-in-one: convex, linear, phased array) and DW-X2S (two-in-one: linear and phased array).
• Model designations shown: X1S / X2S

Key AI Functions

• Auto-IMT: one-click AI recognition and measurement of carotid intima-media thickness for vessel wall quantification and faster exams.
• Automatic Bladder Volume (PVR): boundary detection and automatic volume calculation for rapid urinary assessment.
• Automatic Ejection Fraction (EF): automatic four-chamber tracking and calculation of left ventricular ejection fraction for quick cardiac function evaluation.
• Automatic Muscle and Fat Recognition (optional): AI differentiation and measurements of muscle and adipose tissue.

Hardware & Connectivity

• Ultra-portable, cable-free handheld probe design for true mobility.
• Wi‑Fi connection with up to 15 m range.
• 3000 mAh lithium battery providing approximately 2.5 hours of continuous operation.
