Abstract

Objectives: To propose a better image fusion approach for detecting different stages of cancer and suggesting suitable technique for treating cancer to medical practitioners. Methods: Diagnosis of cancerous region is carried out by wavelet based fusion technique on PET/CT images and the thermal effect on cancer tissue growth is analysed using RF module of COMSOL-Multi-physics software. Findings: Multimodal image fusion technique helps to identify the growth of object which is carried out by wavelet technique. The Computed Tomography (CT) scan helps to determine extent of the cancer, while Positron Emisson Tomography (PET) scan finds areas of cancer spread. There after the results acquired will enhance visual effect and help the medical practitioners to examine the development of tumour. In case of tumour, cell spreads beyond the infected portion of the organ, treatment using chemotheraphy is harmful while, surgery can be fatal, and hence Radio Frequency (RF) heating technique may be a better solution. The important issue in cancer treatment is to bind the area of human body under the RF energy influence, to avoid unwanted radiation or heating effects on healthy human tissue. Applications: The results acquired will enhance visual effect and help the medical practitioners to examine development of tumour. Further in this paper, the various graphs of temperature variation, electric field distribution, degree of tissue injured, at various times instant versus cancer region are plotted, also expression for the space Eletromagnetic (EM) wave propagation and its mathematical analysis is carried out.
