[High-intensity focused ultrasound transducer]

Area of Science:

• Medical physics
• Oncology
• Biomedical engineering

Context:

• High-intensity focused ultrasound (HIFU) is a noninvasive therapeutic modality.
• HIFU is increasingly utilized for cancer treatment due to its precision and safety.
• Advancements in HIFU transducer technology are critical for its clinical application.

Purpose:

• To review and evaluate different types of HIFU transducers used in cancer therapy.
• To compare the performance characteristics of various HIFU transducer designs.
• To highlight the role of transducer development in the efficacy of HIFU treatments.

Summary:

• The paper discusses four HIFU transducer designs: acoustic lens, spherical auto-focused, pluralistic auto-focused, and electronic phased array.
• Each transducer type is presented in the context of its application in HIFU cancer therapy.
• The performance of these four HIFU transducers was evaluated to understand their capabilities and limitations.

Impact:

• Provides a comparative overview of essential HIFU transducer technologies.
• Informs future research and development in HIFU systems for oncology.
• Contributes to the understanding of transducer selection for optimal HIFU treatment outcomes.
