Introduction The long scan duration makes spectroscopic imaging (SI) experiments particularly susceptible to motion-induced artifacts. Prospective motion correction based on an optical tracking system [1] has recently been proposed for 2D SI in the human brain [2]. Additionally, retrospective phase correction using the interleaved reference scan (IRS) method has been applied for the correction ...

INTRODUCTION Cardiac and respiratory fluctuations (physiological noise) are known to be confounding signals in the detection of cortical activation by fMRI. The standard correction method RETROICOR [1] has been used to perform a global correction by folding the whole time series (TS) into only one signal cycle and to use this global template to correct each individual cycle. We extended RETROIC...

Cardiac C-arm CT is a promising technique that enables 3D cardiac image acquisition and real-time fluoroscopy on the same system. Retrospective ECG gating techniques have already been adapted from clinical cardiac CT that allow 3D reconstruction using retrospectively gated projection images of a multi-sweep C-arm CT scan according to the desired cardiac phase. However, it is known that retrospe...

AIM We combined anti-androgen therapy with radiotherapy in a first-line setting for metastatic prostate cancer aiming to cause maximal cancer-cell death to delay the emergence of castration-resistant disease. MATERIALS AND METHODS In this non-randomized retrospective series of 46 patients, the initial median prostate-specific antigen (PSA) was 98.5 μg/l (range=6.7-15,500), median Gleason scor...

abstract   introduction: the purpose of present research was the study of the effect of sensory feedback on speed of the relative phase transition in anti-phase bimanual coordination pattern across old adults. materials and methods: therefore 15 intact male old adults selected in available with age range 60-70 years that were all of them hand-right. participants started their movement on bimanu...

the growing attention to formulaic sequences during the last decade indicates that the functional features of such sequences play a crucial role in writing. formulaic sequences are prefabricated linguistic components which are stored and retrieved as a whole. the present study aims to examine the functional features of such sequences in persian writings. to do so, 10 writing samples of persian ...

Auditory-evoked potentials (AEPs) were triggered in real time as a function of ongoing electroencephalogram (EEG) phase. Phase triggering on-line or retrospective phase-selective averaging introduces phase artifacts such as spurious troughs or peaks, which mask mid-latency and affect the amplitude of late AEPs. We developed a method to control for phase artifacts by phase-selective averaging of...
