The design and implementation of a motion correction scheme for neurological PET.
A method is described to monitor the motion of the head during neurological positron emission tomography (PET) acquisitions and to correct the data post acquisition for the recorded motion prior to image reconstruction. Expand

Detection of Thirty-Second Cognitive Activations in Single Subjects with Positron Emission Tomography: A New Low-Dose H215O Regional Cerebral Blood Flow Three-Dimensional Imaging Technique
Positron emission tomography regional CBF (rCBF) studies of cognitive processes have traditionally required 30–60 mCi of H215O per scan and intersubject averaging to achieve statistical significance.Expand

Image reconstruction of motion corrected sinograms
We discuss a motion correction scheme for rigid body motion in PET if the movement is known. Several groups have previously proposed a 2 stage process for motion correction: acquiring the data inExpand

The on-line monitoring of continuously withdrawn arterial blood during PET studies using a single BGO/photomultiplier assembly and non-stick tubing.
A robust, highly sensitive system is described for monitoring the concentration of positron emitting radioisotopes contained within arterial blood continuously withdrawn during PET studies of theExpand

Imaging Transient, Randomly Occurring Neuropsychological Events in Single Subjects with Positron Emission Tomography: An Event-Related Count Rate Correlational Analysis
Many neuropsychiatric symptom states are idiosyncratic, involuntary, randomly occurring, subjective, and transient. The brain states associated with these clinically important mental states cannot beExpand

Use of 2-[18F]fluoro-2-deoxyglucose as a potential agent in the prediction of graft rejection by positron emission tomography.
BACKGROUND We investigated the potential of predicting allograft rejection by measuring the ability of graft-infiltrating cells to take up 2-[18F]fluoro-2-deoxyglucose ([18F]FDG). This molecule is aExpand

A new human (psycho)pharmacology tool: the multiple organs coincidences counter (MOCC)
We describe a novel instrument which is capable of measuring the uptake of radioligand in human organs in vivo with the administration of very small doses of positron-emitting radioligands. ThisExpand

Dosimetry of intravenously administered oxygen-15 labelled water in man: a model based on experimental human data from 21 subjects
Models based on uniform distribution of tracer in total body water underestimate the absorbed dose from H215O because of the short half-life (2.04 min) of 15O, which leads to non-uniform distributionExpand

A comparison of 3D scatter correction methods in a neuroPET tomograph
A comparison has been made between two procedures for scatter correction of 3D PET data acquired on a brain scanner (CTI/Siemens 953B). The methods are (i) dual energy window (DW), in which aExpand
