Patent number: 11959990Abstract: An MRI phantom for calibrated anisotropic imaging includes a plurality of separate sheathed taxons or integral taxons sharing common taxon walls, wherein each taxon has an inner diameter of less than 5 microns. The taxons form taxon filaments that are combined to form taxon ribbons. The taxons may have an average inner diameter of less than 1 micron, specifically about 0.8 microns with a packing density of about 1,000,000 per square millimeter. The filaments may include structural features such as an outer frame and crossing support ribs and may further include a visible alignment feature that allows for verifying orientation of an individual filament. The taxons may be formed as taxon fibers manufactured using a bi or tri-component textile/polymer manufacturing process. An anisotropic homogeneity phantom may include frame members that support fiber tracks extending in orthogonal directions, wherein each fiber track is formed of taxons.Type: GrantFiled: June 21, 2022Date of Patent: April 16, 2024Assignees: PSYCHOLOGY SOFTWARE TOOLS, INC, UNIVERSITY OF PITTSBURGH—OF THE COMMONWEALTH SYSTEM OF HIGHER EDUCATIONInventors: Anthony P.

Patent number: 8214012Abstract: Critical needs for MRI patient instruction, testing, comfort, motion control, and speech communication are provided for better imaging which leads to more effective medical care. An MRI Digital Video Projection System is disclosed which provides better quality display to the patient to better inform, instruct, test, and comfort the patient plus the potential to stimulate the brain with microsecond onset times to better diagnose brain function. An MRI Motion Tracker and Patient Augmented Visual Feedback System enables monitoring patient body part motion, providing real time feedback to the patient and/or technician to substantially improve diagnostic yield of scanning sessions, particularly for children and mentally challenged individuals. An MR Forward Predictive Noise Canceling Microphone System removes the intense MRI acoustic noise improving patient communication, patient safety and enabling coding of speech output. These systems can be used individually but maximum benefit is from providing all three.Type: GrantFiled: June 17, 2005Date of Patent: July 3, 2012Assignees: Psychology Software Tools, Inc., University of PittsburghInventors: Anthony P.

Patent number: 8142196Abstract: Creating and executing real-time psychological experiments with sub-millisecond time precision uses a Hierarchical Experiment Spreadsheet (HES) providing a hierarchical data structure and interface. The user adds/modifies experiment levels in a spreadsheet multilevel table representation. New objects and properties are added while maintaining the hierarchical structure of the experiment and prohibiting user corruption of the experiments hierarchical structure. A Time Event Queue Manager (TEQM) provides precision timing using event pre-release synchronization, compensating for timing errors produced by the personal computer operating system and enabling sub-millisecond time precision.Type: GrantFiled: February 14, 2006Date of Patent: March 27, 2012Assignee: Psychology Software Tools, Inc.Inventors: Anthony P.
