OBJECTIVE The purpose of this study is to estimate a patient's organ dose (effective dose) during performance of dual X-ray absorptiometry by using the correlations derived from the surface dose and the depth doses in an anthropomorphic phantom. MATERIALS AND METHODS An anthropomorphic phantom was designed and TLDs (Thermoluminescent Dosimeters) were placed at the surface and these were also ...

In this work we take a new approach to the determination of the quantified contribution of various attributes of the human hand to its dexterity, with the aim of transposing this knowledge into supportive guidelines for the design of anthropomorphic robotic and prosthetic hands. We have carried out a number of standard dexterity tests on normal human subjects with various physical constraints a...

Many industrial applications are well suited to non-anthropomorphic pick and place robots. Robotworld is adept at performing vertical assembly operations, which may constitute 60% of all manufacturing operations. Furthermore, non-anthropomorphic robots can achieve higher accuracy than anthropomorphic (six degree of freedom) robots because they can be calibrated to higher precision. In this repo...

One of the main benefits of educational robotics is its potential to inspire curiosity and creativity in students. Creativity in educational robotics has been typically associated with the constructionist learning paradigm and the processes of building, programming and manipulating task-centric robotic platforms. On the other hand, there has been a growing tendency recently to use anthropomorph...

PURPOSE To develop an anthropomorphic phantom to simulate heart, lung, and blood motion. Magnetic resonance imaging (MRI) is sensitive to image distortion and artifacts caused by motion. Imaging phantoms are used to test new sequences, but generally, these phantoms lack physiological motion. For the validation of new MR-based endovascular interventional and other techniques, we developed a dyna...
