Global Healthcare Medical Palm-Sized Wireless Linear Color Doppler Ultrasound Scanner with Magnetic Navigation

Model: GHM 6X HK

The Global Healthcare Medical Palm-Sized Wireless Linear Color Doppler Ultrasound Scanner is a compact, probe-type diagnostic imaging system engineered to bring advanced needle visualization and precise puncture guidance directly to the point of care. Weighing just 200g (approximately 0.44 lbs) and measuring 156mm × 55mm × 20mm, this handheld device fits comfortably in the palm of your hand—yet delivers high-resolution linear imaging with an integrated magnetic navigation system that transforms how clinicians approach ultrasound-guided procedures.

What sets this scanner apart is its magnetic navigation technology for needle visualization. The probe contains a built-in magnetic sensor that captures the environmental magnetic field vector and the magnetized needle‘s induced magnetic field vector. This information is transmitted to a processing unit that calculates the needle’s displacement and angle in real time, generating an augmented ultrasound image with the puncture needle‘s position and trajectory overlaid directly on the display. The result is multi-directional, cross-verified needle visualization that improves puncture accuracy, raises intervention success rates, and reduces procedural difficulty—all without the need for a traditional puncture frame or bracket.

The system operates wirelessly via WiFi, transmitting real-time images directly to your smartphone, tablet, or PC. Compatible with Apple iOS, Android, and Windows devices, it eliminates the need for bulky consoles and tangled cables, giving clinicians complete freedom of movement during examinations and procedures.

Key Features & Benefits

Magnetic Navigation for Precision Needle Visualization

The scanner‘s defining feature is its integrated magnetic navigation system, which provides real-time visualization of the puncture needle within the ultrasound image. Unlike conventional ultrasound guidance that requires the operator to mentally track the needle tip, this technology overlays the needle’s displacement and angle directly onto the ultrasound image, enabling simultaneous visualization of the needle and surrounding anatomy.

Key advantages of magnetic navigation:

• In-plane and out-of-plane puncture support – clear needle tip visualization regardless of the puncture approach

• Multi-directional and cross-verified visualization – more reliable confirmation of needle position

• No puncture frame required – simplifies setup and reduces equipment dependency

• Improved puncture accuracy – higher success rates and reduced intervention difficulty

• Real-time trajectory projection – supports precise needle alignment throughout the procedure

Clinical evidence supports the benefits of magnetic needle navigation. A systematic review and meta-analysis found that magnetic field needle positioning for ultrasound-guided central venous cannulation was associated with higher out-of-plane success rates and significantly fewer complications, including a 70% reduction in posterior wall puncture rates and an 86% reduction in artery puncture rates compared to conventional ultrasound.

High-Frequency Linear Array for Superior Superficial Imaging

The scanner is equipped with a linear array probe featuring 192 piezoelectric elements and 32 channels, optimized for high-resolution imaging of superficial structures. The 40mm scan width provides a broad field of view for efficient examination of tendons, ligaments, nerves, blood vessels, and small parts. Key imaging specifications include:

The adjustable scanning depth from 20mm to 100mm allows you to adapt the imaging depth to the specific clinical application—from very superficial structures such as skin and subcutaneous tissue to deeper musculoskeletal and vascular targets.

Comprehensive Imaging Modes

The system supports a full range of imaging modes for diverse clinical applications:

• B‑Mode – fundamental 2D imaging with 256-level gray scale

• B/M Mode – combined anatomical and motion imaging

• Color Doppler – real-time blood flow visualization

• Power Doppler Imaging (PDI) – sensitive low-flow detection

• Pulsed Wave Doppler (PW) – quantitative blood flow velocity assessment

Image adjustment features include gain (30–105 dB), focus, reverse pulse harmonics, and noise reduction (0–4 levels). Dynamic range is adjustable across 8 settings (40–110).

Extended Battery Life with Wireless Charging

The system features a built-in 5600mAh lithium battery providing approximately 3 hours of continuous working time. With wireless charging, working time can be extended indefinitely—simply place the probe on a compatible charger between scans. Charging is also available via USB for universal convenience.

Wireless Freedom for Point-of-Care Imaging

The scanner connects wirelessly to your mobile device or PC, offering:

• Real-time image display – instant visualization on your existing screen

• Image/video storage – save in jpg, mp4, and DCM formats directly to your mobile phone or tablet

• Broad compatibility – works with Apple iOS, Android, and Windows devices

• WiFi type – 802.11n / 2.4G / 5G dual-band 450Mbps for fast, stable transmission

Puncture Assistance for Guided Procedures

The system includes a comprehensive suite of puncture assistance tools:

• In-plane puncture guide line – for precise needle alignment within the scan plane

• Out-of-plane puncture guide line – with automatic blood vessel measurement function

• Magnetic navigation needle visualization – real-time overlay of needle position and trajectory

• Automatic vascular measurement – supports pre-procedure vessel assessment

Comprehensive Measurement and Review Tools

• Measurements – distance, area, circumference, heart rate, and obstetric calculations

• Cineplay – manual and automatic playback with adjustable frame settings (100 / 200 / 500 / 1000)

• Image gray scale – 256 levels for detailed tissue differentiation

• Image frame rate – 18 frames/second for smooth, real-time visualization
