Introduction: Sentinel lymph node biopsy (SLNB) is a standard surgical technique to identify sentinel lymph node (SLN) for the staging of early breast cancer. Nowadays, two methods are used for the identification of SLN: blue dye method aiding visually and radioactive dye using gamma detector. A wide range of gamma probe systems with different design and performance are used in...
Background & Aims: Spatial resolution is one of the important features of evaluating the function of nuclear medicine imaging systems. The aim of this study was evaluating the capability of the spatial resolution in images of nuclear medicine planar by calculating the modulation transfer function (MTF). Materials & Methods: Nuclear medicine imaging of capillary tube with activity 1 mCi was per...
background: to date, several imaging techniques to track stem cells are used such as positron emission tomography (pet), single photon emission computed tomography (spect), bioluminescence imaging (bli), fluorescence imaging, ct scan and magnetic resonance imaging (mri). although, overall sensitivity of mri compared to spect and bioluminescence techniques are lower, but due to high spatial reso...
LISFLOOD-FP belongs to a new generation of hydrodynamic models of flood simulation, which is implemented by a digital elevation map for the river and the waterways, route information and flow rates The LISFLOOD-FP features are two-dimensional hydraulic models: 1. based on raster 2. large scale 3. ease of formulation and high computational efficiency 4. simplicity of use 5. spatial adjustmen...
