AI-Powered Innovation in Neck Ultrasound Diagnostics | PAU2A

As an advanced AI-powered neck ultrasound device for thyroid nodule detection and classification, Periodmed PAU2A adopts non-invasive high-frequency sound wave imaging. Equipped with a three-in-one probe (convex, linear, phased array) and 128/64 element channels, it offers a wide scanning range, enabling deep tissue detection including the heart and abdomen. It precisely visualizes thyroid and parathyroid glands, efficiently identifying nodules, growths, and abnormalities to support accurate classification, laying a solid foundation for clinical decision-making.

The AI-assisted neck ultrasound imaging for cervical lymph node screening by PAU2A integrates Tissue Harmonic Imaging (THI) technology. By capturing secondary harmonics from tissue boundaries, THI significantly enhances contrast resolution and eliminates artifacts, delivering clearer soft tissue images . This non-invasive, painless tool excels at visualizing cervical lymph nodes, aiding in the detection of swollen glands and potential metastases. Its quick imaging process helps determine the need for further biopsy, greatly improving lymph node screening efficiency in clinical settings.
Featuring real-time AI analysis, the Periodmed PAU2A serves as a cutting-edge neck ultrasound system for thyroid disease diagnosis. Its built-in 3200mAh rechargeable lithium battery supports up to 3 hours of continuous scanning, minimizing downtime and maximizing diagnostic efficiency. The device provides real-time images of thyroid structures, assisting clinicians in evaluating nodules, abnormalities, and functional disorders. This non-invasive solution accelerates diagnosis workflows, from initial screening to determining biopsy necessity, optimizing thyroid disease management.
As a portable AI neck ultrasound machine for outpatient neck soft tissue evaluation, PAU2A boasts a lightweight, pocket-sized design. Supporting wireless charging and multi-terminal connectivity (IOS, Android, Windows), it offers exceptional usability in outpatient clinics, emergency scenarios, and MSK point-of-care settings. It comprehensively assesses neck soft tissues including thyroid glands, parathyroid glands, and carotid arteries, delivering quick, painless examinations to diagnose conditions like nodules and artery blockages, perfectly meeting the mobility needs of modern clinics.
Periodmed PAU2A features IPX7 water resistance (1m depth for 30 minutes ), ensuring durability in diverse clinical environments. Its wireless connection enhances convenience, especially in operating rooms requiring strict aseptic conditions. The device leverages AI technology to visualize neck structures clearly, aiding in the diagnosis of thyroid disorders, lymph node issues, and vascular blockages. Combining long-lasting battery life, harmonic imaging clarity, and robust waterproof performance, it becomes a reliable companion for sterile clinical practices and complex medical scenarios.
AI is rapidly evolving and is being integrated into portable ultrasound devices to make ultrasound imagings easier to read. Aura AI Device keeps portability in mind to make ultrasound scanning quick and easy.
