Finals | PPT 4 Medical Imaging Informatics Systems Evaluation and Quality Assurance Flashcards
Any facility in which radiation is used in any procedure that involves irradiation of any part of the human for the purpose of diagnosis or evaluation
DIAGNOSTIC FACILTY
Organized effort by the staff operating a facility to ensure that the diagnostic images produced are of sufficiently high quality
QUALITY ASSURANCE PROGRAM
Consistently provide adequate diagnostic information at the lowest possible cost with least possible exposure of the patient to radiation.
QUALITY ASSURANCE PROGRAM
Reduction in lost and misplaced films and reports
PRINCIPLE OF PACS
Reduction of exposures because of the ability to process images
PRINCIPLE OF PACS
Improved diagnostic accuracy because of image processing
PRINCIPLE OF PACS
Faster diagnosis
PRINCIPLE OF PACS
Increase efficiency of departmental operations
PRINCIPLE OF PACS
Saving in archiving personnel
PRINCIPLE OF PACS
Savings in capital cost for darkrooms and storage space
PRINCIPLE OF PACS
TECHNOLOGICAL EVALUATION OF PACS
TO BE CONSIDERED:
- Performance criteria
- Requirements for integration in the existing situation (imaging devices, HIS, public telecommunication networks)
TECHNOLOGICAL EVALUATION OF PACS
MAIN ISSUES:
- Technical performance of the system
- Integration of system with existing imaging devices
- Integration of the system with the RIS and HIS
Involves a direct comparison with conventional diagnostic activity carried our on films
CLINICAL EVALUATION OF PACS
CLINICAL EVALUATION OF PACS
MAIN ISSUES:
- Clinical acceptability of the system
- Ease of use
- Diagnostic efficacy (CRT vs. Film)
Transmission of a full set of full integrity of images to a center distant from where the images were generated
TELERADIOLOGY
TELERADIOLOGY PURPOSE:
- Primary diagnostic interpretation
- Expert secondary consultation
- Preoperative surgical planning
Provide access to medical image reporting for underserviced centers
TELERADIOLOGY
Support patient consultations and inform patient treatment decisions
TELERADIOLOGY
Provide access to image interpretation for remote regions
TELERADIOLOGY
QUALITY ASSURANCE PROGRAM OBJECTIVES
- Maintain optimal quality of diagnostic images
- Reduce unnecessary radiation exposure to patient and staff
- Cost effective
Provide reporting in shifts to provide timely interpretations after normal working hours
TELERADIOLOGY
QUALITY ASSURANCE PROGRAM PRIMARY GOAL
Ensure the consistent provision of prompt and accurate diagnosis of patients.
QUALITY ASSURANCE PROGRAM Principles
- QUALITY CONTROL
- ADMINISTRATIVE PROCEDURE
- PREVENTIVE MAINTENANCE PROCEDURE
- TRAINING
Involves specific actions design to keep measurable aspects of the process involved in manufacturing a product (image) or providing a service within specified limits
QUALITY CONTROL
QUALITY CONTROL aka
“INTEGRAL PART OF QUALITY ASSURANCE”
QUALITY CONTROL Steps
I. Acceptance testing to detect defects in equipment that is newly installed/undergone major repair
II. Establishment of baseline performance of the equipment
III. Detection and diagnosis of changes in equipment performance before they become apparent in images
IV. Verification of causes of deterioration in equipment and have it corrected
ABCD
Designed to verify that QC testing is effective
ADMINISTRATIVE PROCEDURE
ADMINISTRATIVE PROCEDURE includes recommendations regarding the responsibility for (1), (2), (3) and selection
of the (4) for each examination
- QA action
- staff training
- equipment standards
- appropriate equipment
Performed on a regularly scheduled basis
PREVENTIVE MAINTENANCE PROCEDURE
Prevent breakdowns due to equipment failing w/o warning signs detectable
PREVENTIVE MAINTENANCE PROCEDURE
Visual inspection of mechanical and electrical characteristics of XR system
PREVENTIVE MAINTENANCE PROCEDURE
Renovating the manufacturer’s recommended procedures for cleaning and maintenance of equipment
PREVENTIVE MAINTENANCE PROCEDURE
Regular inspection and replacement of switches and parts that routinely wear out/fail
PREVENTIVE MAINTENANCE PROCEDURE
Provide appropriate training for all personnel w/ QA responsibilities (especially those directly involved with QC testing)
TRAINING
Ensure each meet a minimum level of competency to perform QC test correctly and consistently
TRAINING
Provide seminars and training courses on how to perform QC test
TRAINING
Personnel in the program who are responsible for the oversight of the QA program
QUALITY ASSURANCE COMMITTEE
Setting the goals and direction, determining policies and assessing the effectiveness of QA activities
QUALITY ASSURANCE COMMITTEE
