Abstract: A scoring server for assessing technical skills in a practical environment. A client application acts as a middle man between a terminal and an operating system to capture and forward all input from and output to students to the scoring server. The scoring server compares recorded student activity against a list of tasks deemed capable of accomplishing course objectives assigned to students. As objectives are met by a student, the students' grade is updated in real-time. Each student passes or fails an exam based on tasks performed and skills employed. The client application exists for two operating system types: WINDOWS® and LINUX®. A LINUX® client employs a pseudoterminal to permit access to terminal input/output and communication through stdin, stdout, and stderr channels. A windows client (WC) comprises a WC command line activity logger and a WC monitor process to intercept all communication through stdin, stdout, and stderr communication channels.

Abstract: A method for increasing the temporal fidelity, increasing the temporal sampling density, and/or reducing the temporal noise of a series of image frames obtained with a medical imaging system is provided. The image frames are acquired with the medical imaging system. The medical imaging system may be, for example, an x-ray C-arm imaging system. A window function that is representative of a temporal fidelity window is selected and used to temporally deconvolve the image frames using a minimization technique. A temporal sampling density may also be selected and used in the temporal deconvolution. The resultant deconvolved image frames have a higher temporal fidelity to a time-varying image contrast depicted in the acquired image frames, and may also have an increased temporal sampling density and/or reduced temporal noise.
