BACKGROUND While fluorodeoxyglucose (FDG) and amyloid PET is valuable for patient management, research, and clinical trial of therapeutics on Alzheimer's disease, the specific details of the PET scanning method including the PET camera model type influence the image quality, which may further affect the interpretation of images and quantitative capabilities. To make multicenter PET data reliabl...
Freehand three-dimensional (3D) ultrasound is a technique for acquiring ultrasonic data of a 3D volume with application in radiotherapy and surgery planning.
