Full Field Digital Mammography System HAWK

Product Overview

The HAWK Digital Mammography System (Model: HAWK) is a state-of-the-art tungsten‑target digital mammography unit designed specifically for high‑precision breast imaging. Manufactured by Beijing Zhongyan Haikang Technology Co., Ltd. (RLahealth) — a national high‑tech enterprise with nearly 20 years of dedicated expertise in breast imaging — this system represents the culmination of continuous innovation, from the first full‑field digital mammography system using a 70μm detector in 2011 to the current advanced tungsten‑target, amorphous‑selenium, 65μm, AI‑integrated generation launched in 2019. With nearly 1,000 units of successive generations in clinical service across all major provinces of China since 2005, the HAWK has earned a strong reputation for superior image quality, elegant design, and clinical reliability.

Key Technical Specifications

Structural and Ergonomic Innovations

1. Patented 3‑Dimensional Tilt C‑Arm
The C‑arm features motorized three‑dimensional tilt adjustments (vertical, lateral, and anteroposterior). This patented design enables clinicians to achieve optimal patient positioning, particularly for capturing more axillary breast tissue — up to 10% more than standard vertical imaging — which is critical for comprehensive evaluation of axillary lymph nodes. The mobility also facilitates imaging for patients with challenging body habitus, including wheelchair users, elderly individuals, and those with orthopedic limitations.

2. Movable Compression Paddle
The system includes two dedicated breast compression paddles with lateral mobility, allowing the paddle to shift horizontally to capture additional axillary lymphatic tissue during imaging. The combination of electric compression (200N) and manual compression (300N) provides flexibility to balance patient comfort with optimal image quality.

3. Auto‑Retractable Carbon‑Based Grid
The high‑density carbon‑based anti‑scatter grid (imported from JPI, Korea) automatically retracts during magnification radiography. When performing small‑focal‑spot magnification views, the grid retraction is essential for achieving high‑resolution detail without grid line artifacts — a critical function for accurate microcalcification and fine‑structure evaluation.

4. Dual‑Button Exposure System
A dual‑button exposure activation system is incorporated to prevent inadvertent exposure, enhancing operational safety.

Advanced Imaging Performance

Tungsten Target + Rhodium/Silver Filtration
The HAWK system employs a tungsten‑target X‑ray tube paired with rhodium and silver filters — an optimal combination for modern digital flat‑panel detector technology. Compared to traditional molybdenum‑target systems, the tungsten target offers superior penetration and delivers a 30‑60% reduction in radiation dose while maintaining excellent image quality. This makes the HAWK particularly well‑suited for imaging dense breast tissue, which is prevalent among Asian women.

High‑Frequency Generator
The 100 kHz high‑frequency, high‑voltage generator ensures stable, consistent output with precise KV control (20‑40 kV), contributing to reliable image quality across a wide range of breast densities and thicknesses.

Amorphous Silicon Detector
The 85μm pixel detector provides high spatial resolution with a 24×30 cm field of view, generating a 2816×3528 pixel image matrix that captures fine structural details essential for early lesion detection.

Artificial Intelligence Integration

The HAWK system is equipped with the Dr.Wise Breast Imaging AI‑Assisted Diagnosis System, which leverages deep learning algorithms to assist radiologists in detecting and characterizing suspicious findings. AI support enhances diagnostic confidence, reduces interpretation time, and improves early detection rates — particularly important in high‑volume screening programs.

Clinical Applications

• Screening Mammography — Routine breast cancer screening in asymptomatic populations

• Diagnostic Mammography — Evaluation of symptomatic patients with breast lumps, pain, or nipple discharge

• Magnification Views — Detailed assessment of microcalcifications and fine architectural distortions

• Axillary Imaging — Evaluation of axillary lymph nodes and accessory breast tissue

• Preoperative Localization — Guidance for wire‑localized biopsy and surgical planning

• Patients with Dense Breasts — Ideal for Asian women with dense glandular tissue, where conventional molybdenum‑target systems may underperform

Clinical Advantages

1. Superior Image Quality
The combination of tungsten target, optimized filtration, high‑frequency generator, and fine‑pixel detector delivers exceptional image contrast and spatial resolution, enabling early detection of subtle lesions.

2. Reduced Radiation Exposure
The 30‑60% dose reduction compared to conventional mammography systems significantly enhances patient safety, supporting compliance with ALARA (As Low As Reasonably Achievable) principles in breast imaging.

3. Enhanced Diagnostic Confidence
The integrated AI‑assisted diagnosis system provides computer‑aided detection (CADe) and computer‑aided diagnosis (CADx) support, helping reduce interpretive errors and improving workflow efficiency.

4. Improved Patient Accessibility
The 3D‑tilt C‑arm and movable compression paddle accommodate a broader range of patients, including those with limited mobility, small breasts, or prosthetic implants, ensuring equitable access to high‑quality breast imaging.

5. Operational Efficiency
The auto‑retractable grid and intuitive control interface streamline workflow, reducing examination time and technologist workload while maintaining consistent image quality.
