Opis:
The aim of a quality assurance program is to assist a radio-diagnostic facility in consistently obtaining adequate radiological information with a minimum of dose and a minimum of cost. An integrated part of a quality assurance program is quality control ascertaining quality by measurements and other procedures. When procuring equipment, a specification is worked out taking into account all aspects of the performance of the equipment including the desired tolerances of technique factors. In this study the seven tests (beam alignment, beam collimation, reproducibility, accuracy of kv, time accuracy, half value layer (HVL) and leakage) were carried out for the newly installed General X-Ray machine at Nuclear Malaysia and were in the acceptable limits. Such a test will be the responsibility of a qualified physicist or engineer. The status test is carried out in order to establish the functional status of the equipment. The test is performed immediately after the acceptance test or as an integrated part of it. The test will be repeated when repair influencing the functional status has taken place like the acceptance test; the status test will comprise absolute measurements and will likewise be the responsibility of a qualified physicist or engineer.

Opis:
Several momentous and significant events happening all over the world make this paradigm change in the method of teaching in the Asian countries. The first is globalization. High technology has shrunk the world so drastically that professionals have to complete with others internationally. This simply means that if Engineering students do not learn effectively, the graduates will hardly stand a chance in the global competition. This research presents information on the status of accreditation and evaluation of engineering programs in different countries around the world. The focus will be on United States ABET criteria 2016, the Canadian Council of Professional Engineering criteria and the FEANI standards for European institutions Accreditation policies and procedures of other countries are also described briefly in the research. Information on mutual recognition agreements and the cross border recognition of engineering education will also be emphasized.

Opis:
The quality assurance (QA) and quality control (QC) programmes of imaging equipment are key ingredients of a quality system. This study is aimed at measuring X-Ray machine parameters and comparing them with the American Association of Physicists in Medicine (AAPM) report No. 74. Also, this study made comparison with similar articles locally and internationally. The study was conducted in 12 X-Ray unit (A-L) located in Delta State. A MagicMax Universal Basic Unit was used alongside an XR Multidetector (silicon photodiode) to measure dose, dose rate, practical peak voltage (PPV), exposure time, current in milliampere (mA) and quantity (Q) in milliampere seconds (mAs). The XR Multidetector was positioned at 100 cm from the focus to image distance (FID) to make most measurements. Six (6) X-Ray units were above 20 years, accounting for 50% of the total X-Ray units used. 30% of X-Ray units > 20 years failed the QC test, which was 2.3 times higher than X-Ray units < 10 and 10-20 years respectively. On the average, 55% pass mark was achieved in the 12 X-Ray units across the state, while 26.11% of the test could not be done due to bad knobs and other challenges. Two (2) X-Ray units with an average age of 3 years, passed all the test. The study showed that many of the X-Ray units were old and certain machine parameters could not be assessed. The study also reveal that most X-Ray specifications manual were either misplaced or missing. Continuing QC programme is highly recommended in the studied areas.
