© 2021 IEEE.Tumorous tissues generate more metabolic heat than healthy tissues, in case where the tumor tissue is close to the surface, it is possible to detect the tumor with thermal infrared imaging methods. Deeper tumors can be imaged by increasing the temperature of the tumorous tissue by the externally applied magnetic field. In the simulation study, breast and cancerous tissue were modeled in three dimensions by using realistic values of the tissues. Current was induced with a solenoid coil and temperature changes in the breast model were observed by simulations. At 750 kHz operating frequency, the current that can be applied to the coil, according to the specific absorption rate (SAR) limit value of 10 W/kg, was found 66.5 A. The coil designed in the simulations was realized to be used in the experiments. A series resonant circuit and a power amplifier were used to energize the coil with the desired current value. Gelatin-based and vegetable-made phantoms with added NaCI were developed to observe the effect of the coil on the breast model. Thus, the coil circuit designed in the simulation and the suitable tumor tissue phantom are realized.

Microwave Sensing of Acoustically Induced Local Harmonic Motion: Experimental and Simulation Studies on Breast Tumor Detection top, Can Baris; TAFRESHI, Azadeh Kamali; Gençer, Nevzat Güneri (2016-11-01) Sensing acoustically induced local harmonic motion using a microwave transceiver system may provide useful information for detecting nonpalpable tumors in dense breast tissue. For this purpose, we propose the harmonic motion microwave Doppler imaging method, in which the first harmonic of the phase modulated signal due to local harmonic motion is sensed. This signal is related to the dielectric, elastic, and acoustic properties of the vibrating region. The purpose of this paper is twofold: 1) to demonstrate...
Induced Current Thermal Imaging in Breast Cancer Detection Tanriverdi, Volkan; Gençer, Nevzat Güneri (2021-01-01) Infrared thermal imaging method has started to be used in routine controls due to the disadvantages (uses ionizing energy, applies pressure) of mammography, which is frequently used in the diagnosis of breast cancer. With passive thermography, infrared radiation emitted naturally from the body surface is detected by a thermal camera and the surface temperature distribution is displayed. Using a passive thermal imaging system with 30 mK thermal sensitivity, 10 mm tumor can be detected at a depth of 12 mm. Th...
Medical Thermal Imaging of Electrically Stimulated Woman Breast: a simulation study Carlak, H. Feza; Gençer, Nevzat Güneri; Beşikci, Cengiz (2011-09-03) Tissues have different electrical conductivity and metabolic energy consumption values depending on their state of health and species. Since metabolic heat generation values show differences from tissue to tissue, thermal imaging has started to play an important role in medical diagnoses. Temperature differences of healthy and cancerous tissue may be changed by means of frequency dependent current stimulation within medical safety limits, and thus, depth dependent imaging performance can be increased. In th...
Three dimensional finite difference time domain simulations on harmonic motion microwave doppler imaging method using realistic tissue models Tatar, Fikret; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2019) Imaging of electromagnetic and elastic properties of the breast tissue can be used to identify cancerous regions in the dense fibro glandular breast tissue at the early stage. Numerical simulations are useful in predicting the performance of the imaging method. In Harmonic Motion Microwave Doppler Imaging Method (HMMDI), tissue is vibrated locally, microwave signals illuminate the tissue and the back scattered Doppler signal component is used to form images. In this thesis, forward problem of HMMDI method i...
Comparison of GST Isoenzyme Expression in Normal and Neoplastic Breast Tissue: Correlation with Clinical and Prognostic Factors OĞUZTÜZÜN, SERPİL; İşcan, Mesude; ÖZHAVZALI, MÜZEYYEN; Sak, Serpil Dizbay (2009-01-01) Glutathione S-transferases in breast tissue play an important role in the susceptibility to the mutagenic effects of chemical carcinogens and in the response of breast tumors to chemotherapy. In this study the immunohistochemical staining characteristics of glutathione S-transferase isoenzymes (alpha, mu, pi, and theta) were investigated in invasive duct carcinomas and in normal breast tissue of 43 patients. The relationships between the expression of the GST isoenzymes and some clinicopathological features...
