3D Continuum radiative transfer in complex dust configurations around young stellar objects and active nuclei II. 3D Structure of the dense molecular cloud core ρ Oph D Abstract. Constraints on the density and thermal 3D structure of the dense molecular cloud core ρ Oph D are derived from a detailed 3D radiative transfer modeling. Two ISOCAM images at 7 and 15 µm are fitted simultaneously by re...

AIM To clarify the usefulness of three-dimensional (3D) ultrasound in the assessment of the fetal head and brain, according to 3D ultrasound surface reconstruction, multiplanar image analysis, three-dimensional angiography, and volume calculation. METHODS We examined 326 normal fetuses between 10 and 40 weeks of gestation using 3D ultrasound (Voluson, 530D, Medison, Seoul, Korea), mainly with...

An approach for 3D surface reconstruction from two uncalibrated views is proposed in this paper. The SUSAN corner detector is used for corners from points in edges, which are detected by Sobel edge operator. After corners matching between two images, the fundamental matrix is estimated to acquire 3D structure from matched corners by an improved weighted linear algorithm, which is based on the e...

Panoramic X-ray (PX) provides a 2D picture of the patient's mouth in panoramic view to help dentists observe invisible disease inside gum. However, it limited information compared with cone-beam computed tomography (CBCT), another dental imaging method that generates 3D oral cavity but more radiation dose and higher price. Consequently, is great interest reconstruct structure from image, which ...

the interactive effects of adjacent buildings on their seismic performance are not frequently considered in seismic design. the adjacent buildings, however, are interrelated through the soil during seismic ground motions. the seismic energy is redistributed in the neighboring buildings through multiple structure-soil-structure interactions (sssi). for example, in an area congested with many nea...

background: meict is the first chlorotoxin-like peptide isolated from the iranian scorpion mesobuthus eupeus. chlorotoxin (ctx) is a neurotoxin that specially binds to (mmp-2) on ma-lignant cells and now is used in treatment of glioma. in the present study, we have used homology modeling to propose the 3d structure of meictand analyze its interaction with mmp-2 and its snp types. methods:the st...

today radiology and imaging are the only and main method to generate geometrical data from body. 3d model of the body will give us the best and reliable information for better understanding and diagnostic. on the other hand with development of cad/cam and rapid prototyping, the 3d printers were born to build 3d models without considering the geometry. today the 3d printers are able to makes a 3...

The foundation for the development of GIS throughout a local government is cadastral GIS applications. The applications need to maintain the cadastral data known as the tax assessment role, to evaluate land values including buildings and physical structures. Because the current 2D Cadastre systems with 3D visualizations (ArcScene) is a framework to support comprehensive land-related information...

This work aims at three goals: first, to define a set of statistical parameters and plan structures for a 3D pretreatment thoracic and prostate intensity-modulated radiation therapy (IMRT) quality assurance (QA) protocol; secondly, to test if the 3D QA protocol is able to detect certain clinical errors; and third, to compare the 3D QA method with QA performed with single ion chamber and 2D gamm...
