- W2574456002 abstract "1822 Objectives Motion of the head and neck during PET/CT imaging results in degraded image quality and reduced diagnostic confidence. The objective of this work is to present new technology based on positron emission particle tracking techniques (currently under internal patent review). These new methods require no electronic hardware or invasive camera systems, and offer high resolution tracking of motion that can automatically detect and correct patient movement during imaging. Methods All patients were imaged on a Biograph mCT Flow. Low activity sources were placed on the head of PET/CT patients. Sources were placed in asymmetrical locations to enable full 3D tracking. Patients were asked to move during their scan, simulating typical patient movements during imaging. PET data were acquired for 10 minutes in 64-bit listmode format. Our algorithms were used to track head motion during the scan. Data were corrected by calculating centroid locations for each source at time points when the patient was still. Events associated with transitional motion were discarded. The initial CT position was used as the reference position. Subsequent static positions were transformed to the reference frame by calculating transformation matrices from centroid locations calculated by our algorithms. All reoriented static positions were summed to create the final dataset. Results Analysis of images indicated that patient motion during the scan severely degraded the quality of the images. Key features of the brain are hardly discernible. Our algorithms succesfully tracked all 3 static positions during the scan. Following our correction, the images of the brain were crisp with no signs of motion, as shown in the figure. In addition, these methods enabled recovery of ~97% of data. Conclusions Our new tracking techniques for PET imaging enable a robust method for automatic motion correction in head and neck patients. Automatic correction of motion may prevent inaccurate radiological examinations and prevent burdening patients with repeat imaging procedures. Research Support Funding for this work is provided by departmental funds of the Molecular Imaging and Translational Research Program in the Graduate School of Medicine at the University of Tennessee." @default.
