Magnetic induction tomography (MIT) is a promising modality for noninvasive imaging due to its contactless technology. Being a non-contact safe imaging technique, MIT has been an appropriate method in compare to other electrical tomography. In this imaging method, a primary magnetic field is applied by excitation coils to induce eddy currents in the material to be studied and a secondary magnet...

    Background & Aims: Superior Mesenteric Artery Syndrome (SMAS) is a rare cause of upper intestinal obstruction manifested by retching or vomiting. Thanks to the difficulties arising in its diagnosis, it is usually done by elimination of other causes. We tried to report on the radiological manifestation of this rare syndrome aiming to find reliable predictable signs in imaging.   Materials & ...

X-ray computed tomography is an imaging method which makes tomographic images with high contrast and resolution. However, CT-scans deliver much more radiation dose compared with other imaging techniques. The aim of this study was to evaluate two-dimensional dose distribution in a PMMA phantom as well as investigationof the effect ofcollimation factor on the dose distribution measuredusing GAF-C...
