To develop a simple, low-cost vascular phantom that combines vessel-mimicking and tissue-mimicking layers, enhancing anatomically realistic ultrasound imaging for improved training and procedural planning.
Key Findings:
PVA-c provides high strength and flexibility for phantom construction, making it suitable for various applications.
The use of talcum powder as a scattering agent significantly enhances ultrasound imaging quality, allowing for better visualization of vascular structures.
The design allows for realistic imaging of vascular structures under IVUS and ICE, which is crucial for effective training.
Interpretation:
The developed phantom effectively mimics the anatomical and acoustic properties of real vascular structures, facilitating better training and research outcomes in intravascular and intracardiac procedures, with potential implications for clinical practice.
Limitations:
The sensitivity of PVA-c to heat may complicate the creation of hollow vessels, suggesting the need for alternative methods.
Variability in ultrasound imaging may still occur due to anatomical differences, highlighting the importance of customizing phantoms for specific applications.
Conclusion:
The study successfully demonstrates a method for creating a realistic vascular phantom that can be used for various ultrasound applications, significantly enhancing training and procedural planning in intravascular and cardiac interventions.
