Summary
Transesophageal echocardiography (TEE) has become vital for cardiologists, offering superior diagnostic information. Advances in TEE transducer technology have significantly improved imaging quality and diagnostic capabilities.
Area of Science:
- Cardiology
- Medical Imaging
- Biomedical Engineering
Background:
- Transesophageal echocardiography (TEE) has become a cornerstone in cardiac diagnostics over the past two decades.
- It provides crucial anatomic and hemodynamic information unobtainable through conventional precordial methods.
- Technological advancements in transducer design have been pivotal to TEE's increasing utility and diagnostic accuracy.
Observation:
- This review focuses on the evolution of TEE phased array probes, highlighting developments at Erasmus University.
- Key transducer parameters influencing image quality, including center frequency, array aperture, and focusing, are examined.
- Simulations are used to illustrate the impact of these parameters on image resolution and artifact generation.
Findings:
- Improvements in transducer technology have led to smaller probes with enhanced imaging capabilities.
- Specific design parameters critically affect the resolution and clarity of 2D echocardiographic images.
- Suboptimal transducer design can result in significant image artifacts, limiting diagnostic value.
Implications:
