    A new localized current field (LCF) hyperthermia system for tumor therapy is presented. This experimental system uses readily available components and a novel temperature regulation circuit for improved safety and performance.

    Area of Science:

    • Oncology
    • Biomedical Engineering
    • Medical Physics

    Background:

    • Localized Current Field (LCF) hyperthermia shows promise for tumor therapy.
    • A commercially available, integrated LCF system is currently lacking.
    • Existing experimental setups often require specialized components for temperature control.

    Purpose of the Study:

    • To present a novel LCF hyperthermia system design.
    • To detail a simple yet effective temperature regulation circuit for LCF systems.
    • To discuss system safety, calibration, and performance aspects.

    Main Methods:

    • Assembly of an experimental LCF system using discrete, general-purpose components.
    • Development and integration of a specific temperature regulation circuit.

  • Evaluation of system safety, calibration procedures, and performance characteristics.

    • Main Results:

    • An experimental LCF system was successfully assembled using accessible components.
    • A functional temperature regulation circuit was designed and implemented.
    • The study provides insights into the safety, calibration, and performance of the developed LCF system.

    Conclusions:

    • The presented LCF system offers a viable approach for experimental tumor hyperthermia.
    • The developed temperature regulation circuit addresses a key limitation in current LCF system assembly.
    • This work facilitates further research and development in LCF hyperthermia therapy.
