Quality Control Measurement

The investigation of Quality Control measurement (QC) with ageing x-ray machines was undertaken. Ten x-ray machines were examined across different hospitals within  Makurdi metropolis, Benue State  using Gammex 330 kV meter and ten (10) X-ray Machines in government hospitals (GH) and private hospitals (PH) with age’s (4-12) years for new X-ray Machines and (22-47) years for aged X-ray Machines. With these, on the quality of diagnostic X-rays and patient’s dose were examined separately when a graph of age of the machine was plotted against the power n of the kVp and a graph of machines age was plotted against radiation intensity. Based on the analysis obtained in this study, the value of n for the new machines with ages (5-12) years has a value of  and aged machines with ages (22-47) years has a value of. This shows that there is a relationship between age and n. In conclusion, the findings of the present study showed that the output radiation dose of new and aged x-ray units differs at the same kVp and mAs measurements, indicating that the x-ray tube deteriorates as its ages increase, thereby posing higher health risk to patients and as such, the study recommends that QC measurement be undertaken on x-ray machines at definite stages of the machines life to verify the effects of aging of a machine on patient's dose.

Abstract. Early detection of breast cancer is the first step in prevention that can be done by women, therefore when one is diagnosed with breast cancer, the appropriate treatment can be performed quickly and accurately. Early diagnosis of breast cancer can be a way of mitigation in preventing breast cancer through the use of mammography. Bureau of Radiology as said by The Joint Commission on Accreditation of Hospitals (JHCA) stated that one of the responsibilities of the radiology unit is to control the quality of service which aims to minimize the radiographic image repetition factor; as well as maximizes the quality of radiographic image. Quality control tests are an effort that is needed on the mammography X-ray diagnostics tools. This is done to maintain the quality of expected output. The parameters that are included within the radiation output are the magnitude of current and the voltage of tube that are produced; therefore they remained constant and correspond to the recommended standard. Bureau of Radiological Health, as said by JHCA mentioned that to control the quality of image which will minimize the radiographic image repetition and maximizes the quality of radiographic image. Therefore the radiation output will not be dangerous later. The early stage of the quality control test on the machine was conducted by setting all the filtrations which were placed to capture the x-ray on the x-ray plane tube with minimum value. Then, ionization chamber is placed on the test subject points; right after that the distance between it to the radiation source is noted. The x-ray film is place on a film on the compression table of the patient and the distance between film and the focus point is noted. This is then exposed using a target filter Mo/Mo by setting the current as well as variation the voltage and time. The standard voltage measurements are 20-33kVp. This data is from the observations of time exposure; the output value is then noted. The above procedure is conducted from the minimum voltage to the maximum voltage. The output ray is measured for each voltage. The same procedure is conducted to the target filter Mo/RH. The results obtained are that the greater the input voltage and current will subsequently produce greater doses, therefore the exposure has exceeded the standard limit 0.1 mHy with longer exposure time. The HVL density thickness on the mammography X-ray machine determined the quality of the beam and the doses of x-ray exposure on the mammography machine. The output stability of x-ray beam exposure in the mammography machine mode Mo/Mo still fulfill the standard which is the value of 69% Keywords: Quality Control, Sinar-X, mammography, Mp/Mo, Mo/RH

Potato is one of popular agricultural products grown and used in the world with high effective economic and nutritional value. In potatoes, there are always have some harmful bacteria species due to the sources of exposure from the seed, soil as well as the post-harvest environment which make deceasing the quality and quantity of potatoes. Usually, irradiation with gamma isotope sources is used in food irradiation, however, the disadvantage of the gamma source is the safe shielding reason even without the use of irradiation. Nowadays, X-ray irradiation in food is one of the methods interest to storage in long time. The first advantage of X-ray irradiation is that most of aerobic bacteria in food is killed, but does it not change the quality of the potato. Moreever, the advantage of an X-ray generator is that it does not have to cover up radiation when not in use. In this study, we have used low energy X-rays emitted from X-ray generator MBR-1618R-BE (Hitachi -Japan) to study the ability to kill aerobic bacteria in potatoes grown in Da Lat. After preparation, potato samples were irradiated at doses ranging from 50 Gy to 5000 Gy. The irradiated samples were homogenized and inoculated on Nutrient Agar and incubated at 370C in an incubator to check the changes of aerobic bacteria. The research showed that the number of aerobic bacteria decreased dramatically to a dose of 1000 Gy (the aerobic bacteria was only less than 0,6%), despite a sharp increase in the dose of irradiation, this number decreased a little. The results also showed that D10 dose was 471,34 Gy.

Uang logam pecahan Rp 1.000,00 merupakan salah satu uang dengan nilai intrinsik yang paling baik dan banyak beredar di masyarakat. Oleh karena penggunaannya yang tinggi, maka kualitas uang logam ini perlu diperhatikan. Kontrol kualitas pecahan uang logam ini perlu dilakukan agar pecahan yang beredar di masyarakat adalah pecahan uang logam yang memenuhi standar. Salah satu cara yang dapat dilakukan untuk mengontrol kualitasnya adalah dengan teknik difraksi sinar-x (XRD). Dengan teknik ini, cacat struktur dapat dideteksi tanpa harus merusak uang logamnya, sehingga uang logam yang cacat struktur dapat dieliminasi dari peredaran. Namun, teknik XRD memerlukan cara tersendiri untuk menginterpretasikannya, oleh karena itu studi ini dilakukan untuk mencontohkan bagaimana cara menginterpretasikannya. Lima buah sampel uang logam pecahan Rp 1.000,00 digunakan dalam studi ini, dimana dari hasil kontrol kualitas yang dilakukan, terdapat satu pecahan uang logam yang terdapat cacat struktur. Dari hasil studi sendiri menunjukkan bahwa kelima sampel memiliki karakteristik struktur FCC yang merupakan target produksi dengan indikator bidang-bidang (111), (200), (220) dan (311). Namun, salah satu sampel ternyata memiliki cacat produksi berupa munculnya karakteristik BCC yang bukan merupakan target produksi dengan indikator bidang (310). Sampel yang memiliki cacat produksi ini dapat direkomendasikan untuk tidak diedarkan. Dari studi ini terbukti bahwa teknik analisis XRD dapat digunakan secara efektif untuk mengontrol kualitas uang logam secara non-destruktif. The IDR 1000 coin is one of the best intrinsic rupiah money and most widely used by Indonesian people. Because of these reasons, the quality of it needs to be considered. The quality control of this coin must be done in order to make sure that it meets the standard quality to distribute. An x-ray diffraction (XRD) technique is one way in order to control the quality of this coin. By using this technique, structural defect on this coin can be detected without destructs it, so that defected coin can be rejected to be distributed. However, this technique needs special technique to interpret it. This study aimed to exemplify how to interpret it. Five IDR 1000 coins were used as samples in this study. From this study, the result shows that there is a coin with structural defect. The results of this study show that all of five samples have FCC characteristics as a production target with (111), (200), (220) and (311) planes as indicators. However, there is a sample with a production defect i.e. BCC characteristics with (310) plane as an indicator. This sample were then recommended to be rejected. Overall, this study shows that this XRD analytical technique can be effectively used for controlling the quality of money coin without destructs it.

Abstract Aim To improve the efficiency of intraoperative hand trauma x-ray review, introduce a scoring system for quality of fixation achieved and use this as an education and feedback tool for trainees. Method A large QI project in 2019 demonstrated that intra-operative images taken using the mini C-arm were not being reviewed. In March 2020 the first QI cycle introduced an Access database to ensure that as cases were removed from the trauma board, they were added to a review list. Each x-ray was also scored in the trauma meeting (good, acceptable, poor) to assess the radiographic quality of fixation. The second QI cycle identified the named surgeon for each case, allowing surgeon specific feedback. Finally, we trained all qualified users of the mini C-arm to upload their own images after each case, reducing the mean time to upload. Results This QI project has improved the review rate of mini C-arm images from 30% to 100% and every x-ray is scored. The mean time to review images has reduced from 4 days to less than 24 hours. All trainees can access their scores for imaged hand and wrist trauma and receive written constructive feedback. Conclusions This project ensures appropriate and prompt review of all hand and wrist trauma cases allowing early identification of any concerns. All x-rays are scored, and this process acts as an educational prompt in the trauma meeting. A final report can be printed for each trainee which can be uploaded to their portfolio to document their surgical progress.
