This study explores the hypothesis that Magnetic Resonance Imaging (MRI) can image the process of electrolysis by detecting pH fronts. The study has relevance to real time control of cell ablation with electrolysis. To investigate the hypothesis we compare the following MR imaging sequences: T1 weighted, T2 weighted and Proton Density (PD), with optical images acquired using pH-sensitive dyes e...

background: the purpose of this study is to fabricate inexpensive in-house low cost homogeneous and heterogeneous human equivalent thorax phantom and assess the dose accuracy of the treatment planning systems (tps) calculated values for different lung treatment dosimetery. it is compared with thermoluminescent dosimeter (tld) measurement. materials and methods: homogeneous and heterogeneous tho...

background: this study assessed the clinical usefulness of the solid phantom, which may compensate for the disadvantages of the water phantom, by comparing the radiological doses between the two depending on their depths. materials and methods: the experimental equipment used was a linear accelerator for medical use, water phantom, solid phantom, farmer type ion chamber and electrometer. the di...

Clear gel ballistic phantom is used in medical physics to model the interaction of soft biological tissues with radiation. With emergence of new technologies like nanomedicine utilizing nanoparticles injected into the tumor and activated by optical radiation, it is important to study the optical properties of those particles injected into the gel phantom. For this purpose, we present the result...

A cylindrical slice of seeded winter melon with an air-cavity was imaged using CT and EIT imaging systems. The structural regions were extracted from the CT image using morphological image processing algorithms and fused with the functional information of its EIT image. Fusion performance showed a detectability increase of 67% along with a structural similarity increase of 26%.

Optical diagnostics in biological materials are hindered by fluorescence and scattering. We have developed a multimodal, multiplex, coded-aperture Raman spectrometer to detect alcohol in a lipid tissue phantom solution.
