Jordan, Peano and others introduced digitizations of sets in the plane and in the 3D space for the purpose of feature measurements. Features measured for digitized sets, such as perimeter, contents etc., should converge (for increasing grid resolution) towards the corresponding features of the given sets before digitization. This type of multigrid convergence is one option for performance evalu...

radiation therapy is considered as one of the main methods in cancer treatment. in this method, determination of exact location and geometric properties of tumor is necessary for treatment planning that leads to increased accuracy and output of treatment and reduction of healthy tissue dose. for this purpose, the aim of the present study has been physiological transmission of gallium as a pharm...

Estimating the quality of standing trees or roundwood after felling is a crucial step in forest production trading. The on-going revolution sector resulting from use 3D sensors can also contribute to this step. Among them terrestrial lidar scanning reference descriptive method offering possibility segment defects. In paper, we propose new reproducible allowing automatically It based on construc...

  Introduction: Geometric distortion is a major shortcoming of magnetic resonance imaging (MRI), which has an important influence on the accuracy of volumetric measurements, an important parameter in neurology and oncology. Our goal is to design and construct a new three- dimensional phantom using a 3D printer in order to measure geometric distortion and its reproducibility in...
