Supervisor:

Department of Biomedical Technology

Synopsis:

The major aim of these lectures is to explain to students the present and probable future possibilities of microwave medical applications. Biological thermal and non-thermal effects of electromagnetic field as well as safety limits are discussed. Microwave thermotherapy applied to cancer and other diseases is described. Details of microwave thermotherapy apparatus are given, especially from the point of view of applicators for local, intracavitary and regional treatment.

Requirements:

Assessment: active participation on the solution of excercises

Examination: fulfillment of requirements for assessment, knowledges covering the extent of the course

Syllabus of lectures:

1. Radiofrequency and microwave applications in medicine.

2. Electrical Parameters of Biological Tissues and Related Measurement Methods.

3. Propagation of Electromagnetic Fields in Biological Tissues - FDTD.

4. Radiofrequency and microwave hyperthermia and ablation: working principles, clinical results, and technical equipment.

5. EM imaging- overview (radiometer, microwave tomography, electrical impedance tomography).

6. Heat Transfer in Biological Tissues. Capacitive, rectangular waveguide, planar, MTM, evanescent mode, intracavitary and interstitial applicators.

7. Treatment planning in microwave hyperthermia.

Syllabus of tutorials:

1. Introduction to exercises and safety in laboratory. Verification of applicator properties - measurement of reflection coefficient and temperature distribution in the phantom of biological tissue.

2. Measurement of dielectric properties of biological tissue phantoms.

3. 1D numerical simulator of propagation of planar wave in biological tissue - implementation in MATLAB.

4. Measurement of dielectric properties of biological tissue phantoms.

5. Differential microwave imaging for temperature monitoring as well as for brain stroke detection.

6. Microwave ablation - experiment and modeling.

7. Treatment planning in full-wave EM simulation tools using patient specific numerical model. Assessments.

Study Objective:

The goal of the course is to introduce students to the fundamentals of EM field applications in modern medicine, particularly in diagnostics and therapy.
