Quality assurance and quality control in radiology pdf
Quality Assurance in HospitalsClick here to access the QA Worksheet. A basic diagnostic imaging quality assurance program is a regulatory requirement in many provinces Footnote 1 , Footnote 2 Footnote 3 Footnote 4 Footnote 5 and in federal institutions. Footnote 10 An ineffective quality assurance program can lead to poor quality radiograms that can impair diagnosis, increase operating costs and contribute to unnecessary radiation exposure to both patients and staff. Any extension of the basic quality assurance program is the responsibility of each x-ray facility. To achieve maximum benefit, all levels of management and technical staff must support and participate in the operation of a well-defined program. This article outlines the essential aspects of a quality assurance program and is intended to encourage the review of a moderate size hospital's x-ray imaging quality assurance procedures.
Diagnostic X-Ray Imaging Quality Assurance: An Overview
Corresponding author: G K Korir ggkk yahoo. The use of X-ray imaging is ever increasing in proportion to the need for radiological services and the latest technology. Quality management of patient radiation dose monitoring is fundamental to safety and quality improvement of radiological services. To assess the level of quality management systems in medical X-ray facilities in Kenya. Quality management inspection, quality control performance tests and patient radiation exposure were assessed in 54 representative X-ray medical facilities. Additionally, a survey of X-ray examination frequency was conducted in hospitals across the country.
This is essential to assure the delivery of safe, cost-effective and high quality diagnostic imaging and radiotherapy services. For Diagnostic Imaging this will include the evaluation and monitoring of patient doses received for a particular radiological examination, protocols and procedures linked to specific imaging procedures, reject analysis and the accuracy of diagnostic imaging reports. Quality assurance embraces all aspects of the diagnostic imaging process including a visual check of the equipment and confirmation of careful preparation prior to every patient procedure as well as establishing a routine quality control testing daily, weekly, monthly, quarterly or annually programme of equipment. Quality control testing includes the monitoring, evaluation and maintenance of equipmentfor optimal performance and stability. Analyzing the results of quality control testing together with initiating corrective action are essential integral components of quality assurance.
The medical physicist performs or supervises the technical aspects of procedures necessary to achieve this objective. The responsibilities of the medical physicist include the development and direction of quality assurance programs. Some of the specifics of practice for a DIMP include [ 1 ]:. Develop procedures for the initial and continuing evaluation of imaging equipment. Measure and characterize the medical radiation from imaging equipment prior to clinical utilization. Perform acceptance testing, evaluation and commissioning of imaging equipment. This has also contributed to the disparity in regulatory requirements for QA and QC across different jurisdictions.
