CardiAQ by SandboxAQ is a groundbreaking magnetocardiography (MCG) device designed for faster and more accurate diagnosis of cardiovascular disease. This mobile, non-invasive device provides rapid, radiation-free imaging of the heart's magnetic signals. CardiAQ utilizes high-performance sensors to detect variations in the heart's magnetic signals and employs advanced Large Quantitative Models (LQMs) to eliminate electromagnetic interference in a hospital environment. The device is compact, operates at room temperature with low power requirements, and needs no specialized cooling or shielding. It can be installed beside a hospital bed or used on a mobile cart for point-of-care diagnostics, and is suitable for use in various settings including emergency rooms, bedsides, and ambulances.
