This paper presents a characterization study of the Sick LMS 200 laser scanner. A number of parameters, such as operation time, data transfer rate, target surface properties, as well as the incidence angle, which may potentially affect the sensing performance, are investigated. A probabilistic range measurement model is built based on the experimental results. The paper also analyzes the mixed ...

Conclusion. Manual mode ultrasound procedure is more accurate in detection of focal liver parenchymal lesions because of reduced specificity in auto mode compared with higher specificity and small percentage of false positive results within manually adjusted scanner. We show the great value of best performance manual setting of the scanner in liver parenchymal focal lesions detecting. OPEN ACCE...

The aim of this study is to understand the trade-off between crystal thickness and scanner axial field-of-view FOV (AFOV) for clinical PET imaging. Clinical scanner design has evolved towards 20-25 mm thick crystals and 16-22 cm long scanner AFOV, as well as time-of-flight (TOF) imaging. While Monte Carlo studies demonstrate that longer AFOV and thicker crystals will lead to higher scanner sens...

PURPOSE To examine reductions in performance on auditory tasks by aphasic and neurologically intact individuals as a result of concomitant magnetic resonance imaging (MRI) scanner noise. METHOD Four tasks together forming a continuum of linguistic complexity were developed. They included complex-tone pitch discrimination, same-different discrimination of minimal pair syllables, lexical decisi...
