Abstract Machine learning and artificial intelligence based techniques have brought great convenience to human life but along with a series of algorithmic “black box”, discrimination ethical issues. One the solutions is integrate machine like expert evaluation research multi-attribute decision-making where “human brain intelligence” used for support “artificial intelligence”. In this article, w...
Background: The present study aimed to introduce a rapid transmission dosimetry through an electronic portal-imaging device (EPID) to achieve two-dimensional (2D) dose distribution for homogenous environments. Material and Methods: In this Phantom study, first, the EPID calibration curve and correction coefficients for field size were obtained from EPID and ionization chamber. Second, the...
Background: The technique of vertical dome division or tip defining, involves incising the lateral crura and vestibular skin at or lateral to the dome or tip defining point. The incision di-vides the lower lateral cartilage into a lateral segment and a medial segment, which are advanced anteriorly and sutured together to increase tip projection. The present study aimed at assessing a new vertic...
Goldman presented a method for computing a versor form of the perspective projection of points in the conformal model. His method starts with a view direction and distance to the projection plane, and constructs the eye point from that information. He then uses a rotor to rotate the eye to the origin. In this paper, an alternate construction using transversion for perspective projection is give...
PURPOSE To display drusen and geographic atrophy (GA) in a single projection image from three-dimensional spectral domain optical coherence tomography images based on a novel false color fusion strategy. METHODS We present a false color fusion strategy to combine drusen and GA projection images. The drusen projection image is generated with a restricted summed-voxel projection (axial sum of t...
