Automatic Scoring of the Collimation Quality Control (qc) Phantom Using Image Processing Techniques

Alnazer Hamza (PhD), M J Alport (PhD), W I D Rae (PhD). Sudan University of Sciences and Technology. University of Kwa-Zulu Natal, Durban, South Africa. ABSTRACT The aim of mammography is to detect any mass lesions or microcalcifications that suggest potentially malignant breast tumors. Digital mammography (DM) has been established as a major imaging modality in diagnostic radiology. However ev...

Quantifiable Closed Quality Control (QC)

To meet the challenge of producing innovative and technologically demanding products economically, companies need the ability of quick and flexible reaction to internal and external disturbances. As a result the companies’ objective shifts from maximization of quality to a “controlled quality” aiming for the stabilization of the operative and strategic value creation process. So the main proble...

Adaptive Selection of Communication Methods to Optimize Collective MPI Operations

Many parallel applications from scientific computing use collective MPI communication operations to distribute or collect data. The execution time of collective MPI communication operations can be significantly reduced by a restructuring based on orthogonal processor structures or by using specific point-topoint algorithms based on virtual communication topologies. The performance improvement d...

Quality-control (QC) performance measures and the QC planning process.

Numerous outcome measures can be used to characterize and compare the performance of alternative quality-control (QC) strategies. The performance measure traditionally used in the QC planning process is the probability of rejecting an analytical run when a critical out-of-control error condition exists. Another performance measure that naturally fits within the total allowable error paradigm is...
