Abstract: Embodiments herein provide an ACsDC converter for generating an ACsDC signal in which AC or DC source can be used to generate the ACsDC signal. The structure of the ACsDC converter consists of three stages, viz., input, isolation, and output. At the input stage, a DC voltage is converted to two AC voltages using power electronic converters. The isolation stage consists of transformers for isolating load and source terminals. The secondary voltages of the isolation transformers are used for obtaining the AC and DC components of the ACsDC signal. At the output stage, the AC component of the output voltage is obtained by using an AC-DC converter and a DC-AC converter. The magnitude, phase, and frequency of the AC component can be controlled. The magnitude of the DC component is controlled using a modulation technique. The AC and the DC component can be combined to obtain the ACsDC signal.

Abstract: Methods, hardware, and software transform 2D anatomical X-ray images into 3D renderings for surgical preparation. X-ray images of a body part are identified by camera model. A contour is extracted from the X-ray. Each anatomical region of the contour is assigned 2D anatomical values. A separate 3D template for the body part is modified to match the X-ray image by extracting silhouette vertices from the template and their projections. The template is aligned with the x-ray image and projected on an image plane to obtain a 2D projection model. The template is modified to match the anatomical values by comparing the projection with the corresponding anatomical values. Best matching points on the contour for extracted silhouette vertex projections are identified and used to back-project corresponding silhouette vertices. The 3D template is deformed so that its silhouette vertices match the target positions, resulting in a 3D reconstruction for the X-ray image.
