MQSA ensures
all mammography services meet minimum standards of quality and excellence
HIPAA sets standards for
electronic record security; electronic formats for record keeping; electronic identifiers and codes; requirements for confidentiality and privacy rules
failure to comply with HIPAA can result in

QM
quality management
quality management is designed to
monitor equipment performance and compliance with industry benchmarks
two key components of quality management
quality assurance and quality control
quality assurance
seeks to get the most efficient performance from both imaging facility and physician
quality control
visible, ongoing effort to collect information about imaging operation
compare bids for
ability to meet required specifications, cost, service, support, and life costs
installation and acceptance testing of equipment is responsibility of
vendor/manufacturer
monitoring problems
establish criteria, monitor performance, collect data, analyze data, and evaluate data

line pair resolution tools; star test patterns; pinhole cameras
