Dynamic Bionic Heart Phantom for MRI Quality Control

The patent transforms the static phantom into a dynamic system by introducing a mechanical drive mechanism that moves the heart model along a preset trajectory to simulate cardiac motion. The heart model includes movable components that can replicate the beating and positioning characteristics of a real heart, enabling the phantom to adapt to dynamic cardiac function imaging quality evaluation requirements.

The patent introduces an ECG signal generation module as an intermediary component that provides standardized electrocardiogram signals to synchronize with the mechanical heart motion. This intermediary system bridges the gap between mechanical movement and clinical software evaluation, enabling comprehensive testing of clinical application software safety by providing a controlled, measurable reference standard.

The patent divides the dynamic phantom into modular segments: a separate mechanical drive mechanism, a movable heart model with distinct chambers, an ECG signal generation module, and a control system. This segmentation allows each component to be independently designed, tested, and adjusted, reducing overall system complexity while maintaining comprehensive cardiac function evaluation capabilities.
