Dogs presented to the Small Animal Hospital of Veterinary Medicine, University of Tehran were included in the present study if spinal or intervertebral disc involvement was suspected. Clinical signs were recorded as well as general information of the patient such as age, breed and sex. Sixty dogs were examined radiographically and two standard orthogonal lateral and ventrodorsal projections wer...
Dt Figure 1 Combined IVIM and DTI for simultaneous assessment of diffusion and flow anisotropy of the kidney Mike Notohamiprodjo, Hersh Chandarana, Artem Mikheev, Jose Garcia Raya, John Grinstead, Thorsten Feiweier, Henry Rusinek, Vivian S Lee, and Eric E Sigmund Department of Clinical Radiology, University Hospitals Munich, Munich, Bavaria, Germany, Center for Biomedical Imaging, NYU Langone M...
Vortex flow imaging is a relatively new medical imaging method for the dynamic visualization of intracardiac blood flow, a potentially useful index of cardiac dysfunction. A reconstruction method is proposed here to quantify the distribution of blood flow velocity fields inside the left ventricle from color flow images compiled from ultrasound measurements. In this paper, a 2D incompressible Na...
Basic physical principles of nuclear magnetic resonance imaging (N.M.R.I), a nonionizing medical imaging technique, are described. Principles of NMRI with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. T1 and T2 and spin density (S.D.) factors and different image construction techniques based on their different combinations is discu...
Fibre optic sensors are well suited to measuring fluid flow in many contexts, and recently there has been burgeoning interest their application direct, invasive measurement of blood within human vasculature. Depending on the sensing method used assumptions made, these intravascular measurements can provide information about local velocity, volumetric flow, flow-derived parameters. be readily in...
Background: Inadequate use of these techniques probably increases the risks of radiography. This study has been accomplished in 2016 to determine medical students and residents of Birjand University of medical science awareness levels of principles of protection in radiologic imaging. Methods: In this descriptive research, all medical students, including externs, interns, radiology residents a...
The image processing technique recognized as super-resolution have proven their valuable in reconstruction high-quality images from a low-resolution image sets. In this paper, author presents new hybrid SR algorithm for medical image processing. The algorithm combines both single and multi frame super-resolution frameworks. The technique derives advantages from rigoristic optical flow motion es...
Ultrasonic imaging is a mature medical technology. It accounts for one in four imaging studies and this proportion is increasing. Wave propagation, beam formation, the Doppler effect and the properties of tissues that affect imaging are discussed. The transducer materials and construction of the probes used in imaging are described, as well as the methods of measuring the ultrasonic field. The ...
