Automatic acquisition of the four-chamber view for 3D echocardiography

Automatic View Planning for Cardiac MRI Acquisition

Conventional cardiac MRI acquisition involves a multi-step approach, requiring a few double-oblique localizers in order to locate the heart and prescribe long- and short-axis views of the heart. This approach is operator-dependent and time-consuming. We propose a new approach to automating and accelerating the acquisition process to improve the clinical workflow. We capture a highly accelerated...

Multi-view passive 3D face acquisition device

Approaches to acquisition of 3D facial data include laser scanners, structured light devices and (passive) stereo vision. The laser scanner and structured light methods allow accurate reconstruction of the 3D surface but strong light is projected on the faces of subjects. Passive stereo vision based approaches do not require strong light to be projected, however, it is hard to obtain comparable...

A portable modular system for automatic acquisition of 3D objects

A portable and flexible system for three-dimensional (3-D) scanning is here presented. It is constituted of four main modules. The first module is devoted to the acquisition of a set of 3-D points over the surface through laser scanning (digitization). The second module reconstructs a continuous 3-D surface, filtering the measurement noise. Whenever required (e.g., in CAD applications), a third...
