Practical considerations of the physical principles of computed tomography or how good are they going to get! WJ Macintyre - 《Journal of Computed Tomography》 被引量: 0发表: 1977年 Physical principles and technical considerations for equine computed tomography and magnetic resonance imaging. This ...
Illustrated throughout, the major components of a CT system are described in relation to the physical principles. An overview of some of the quality control (QC) measures that might be carried out within a CT or SPECT-CT department are also discussed including categories and frequencies of ...
ray computed tomography and X-ray microtomographyis given from first principles, and examples of quantitative applications of the techniques,which generally depend on accurate reconstruction of linear attenuation coefficient values, arediscussed. ... Evershed,NZ Anthony 被引量: 2发表: 2013年 PET/MRI ...

There is good evidence that quantum computers are more powerful than classical computers, and that various simple modifications of quantum theory yield computational power that is dramatically greater still. However, these modifications also violate fundamental physical principles. This raises the question ...
The perceived fragility of the vessel, despite its stress resistance demonstrated throughout the entire study, represented the main challenge for the trainees, purposed to learn principles like respect for tissue, instrument handling, knowledge of instruments and specific procedure [49]. The ...

We have established new principles to design verifiably secure sensors that do not rely on classical cryptographic algorithms and trusted read-out equipment to function, addressing important shortcomings of classical security and privacy approaches to the acquisition and sharing of sensor data. As an exa...
