Wireless Sensor Networks for biomedical applications in cancer hyperthermia

Area of Science:

• Oncology
• Biomedical Engineering
• Medical Physics

Background:

• Deep-seated brain tumors and cancerous cells present significant treatment challenges.
• Focused ultrasound (FUS) is an emerging therapeutic modality for such conditions.
• Hyperthermia, a controlled temperature elevation, enhances FUS efficacy.

Purpose of the Study:

• To investigate the thermal profile of in vitro tumors during FUS-induced hyperthermia.
• To assess temperature changes (4-5°C rise, up to 42.5°C) within tumor layers and directions.
• To develop a system for real-time thermal monitoring and therapeutic control.

Main Methods:

• Utilized an in vitro tumor model with embedded temperature sensors.
• Applied focused ultrasound to induce controlled hyperthermia.
• Developed and implemented a Wireless Sensor Network (WSN) for data transmission.

Main Results:

• Detailed thermal elevation patterns were mapped across different tumor regions.
• The WSN successfully transmitted real-time thermal data from the in vitro tumor.
• The study established a foundation for monitoring and controlling hyperthermia parameters.

Conclusions:

• Focused ultrasound can achieve therapeutic hyperthermia in brain tumors.
• A WSN is a viable tool for remote monitoring of tumor thermal profiles.
• This technology supports precise ultrasound dosage adjustment for patient safety, especially in remote elderly populations.
