3-D gamma knife distribution by normoxic gel dosimetry near tissue inhomogeneties

İşbakan, Fatih. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2005., 2005.)

The primary goal in this study was to investigate the three dimensional dose distributions, near the areas of tissue inhomogeneities, in Gamma Knife Radiosurgery with the normoxic gel dosimetry. Following irradiation, when ...
Inhomogeneous quantum invariance group of commuting fermions

Altıntaş, Azmi Ali. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2004., 2004.)

Since the middle of the twentieth century, physicists have concentrated on finding quantum counterparts of classical systems. When a classical system is quantized its invariance group may still be a classical group. In the ...
Minimization of inhomogeneities in magnetic resonance mammography

Doğruluk, Orkun Serdar. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2006., 2006.)

Magnetic Resonance Mammography (MRM), accepted by for use as asupplemental tool to mammography in 1991, provides detailed information about very small lesions that X-ray mammography and ultrasound often cannot detect. Women ...
