Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).

In this paper, we confirm the feasibility of circular SAR images using real SAR data in both modes: two-dimensional imaging for different view angles, or three dimensional imaging mode. This new imaging possibility demonstrates clearly the strong anisotropic behavior of the main scatterers at X-band. This proves both the limitations of the autofocus techniques base on tracking on isotropic stro...

ABSTXACT This paper describes the study of the possibility of x-ray stress measurement in which stresses are obtained by analyzing the whole of one diffraction ring detected with a two-dimensional x-ray detector called an imaging plate (IP). The theory of the stress determination proposed by Taira et al (1978) was shown and advanced to make measurable all plane stress components. The experiment...

Computer-generated holograms (CGHs) using multiview images (MVIs) are holograms generated with multiple ordinary cameras. This process typically requires a huge number of cameras arranged at high density. In this paper, we propose a method to improve CGH using MVIs that obtains the MVIs by using voxel models rather than cameras. In the proposed method the voxel model is generated using the shap...

Background: Cone-beam computed tomography (CBCT) scanners for image-guided radiotherapy are in clinical use today, but there has been no consensus on uniform acceptance to verify the CBCT image quality yet. The present work proposed new methods to fully evaluate the performance of CBCT in its three-dimensional (3D) reconstruction space. Materials and Methods: Compared to the traditional methods...

in this paper, a new method for determining position and orientation of a coordinate system using its image is presented. this coordinate system is a three dimensional non-orthogonal system in respect to the two dimensional and orthogonal camera coordinate system.  in real world, it’s exactly easy to select three directions on an object so that they don’t be orthogonal and on a plane. the image...
