Abstract

Radiasi yang digunakan dalam kesehatan memang memberikan manfaat yang lebih baik dibandingkan efek yang ditimbulkan, namun radiasi ini tetap memiliki efek sebagai karsinogen bagi organisme hidup terutama kadar limfosit dalam darah. Tujuan penelitian ini adalah untuk melihat peningkatan limfosit setelah terpapar radiasi Sinar-X dengan pemberian susu sapi dan susu kedelai (Susu Soya). Desain yang akan dilakukan pada penelitian ini adalah penelitian eksperimental laboratories dengan rancangan posstest only control group design. Peralatan yang dibutuhkan berupa Pesawat sinar X, Tabung reaksi, Buku dan alat tulis, Mikroskop Bahan habis bahan yang dibutuhkan seperti, Susu Soya, Susu sapi steril, 21 tikus jantan. Berdasarkan hasil penelitian melalui hasil uji statistik dengan menggunakan uji ANOVA One Way diperoleh nilai significant = 0,000 (p > 0,05) sehingga Ho ditolak dan Ha diterima, maka dapat disimpulkan bahwa terdapat perbedaan antara rerata jumlah limfosit pada mencit dengan pemberian susu sapi, susu kedelai, dan tanpa pemberian susu.

Abstract

Radiology is a medical science that focuses on imaging technology. with results in the form of images /images for. to establish a diagnosis by looking at parts of the human body using X-rays so as to be able to provide professional examination services. The results of research that have been conducted at Aulia Hospital regarding the selection of CT scanogram settings for head scans with clinical chepalgia using the upper limit of the vertex and the lower limit of the mandibular because the location of the abnormality in the patient is not known whether in the nerve or sinus, if the scanogram is made to the lower limit of the petrous pars it still cuts the cerebrum so that the sinuses are still cut. whereas in the Radiology installation of Reksodiwiryo Padang Hospital uses a scanogram of the lower limit of the cranii base and the upper limit of the vertex to minimize the radiation received by the patient. Based on this, socialization activities through a pocket book of research results were carried out at Reksodiwiryo Padang Hospital on August 10, 2023 starting at 08.00 - 12.00 WIB, with participants being radiographers in the Radiology installation of Reksodiwiryo Padang Hospital.  The methods used were lecture, discussion and question and answer. With communication that is two way traffic, there is a direct reciprocal relationship between the speaker and the participants or vice versa. This method applied can focus the attention of participants in training to develop thinking power and skills to express opinions in the form of exchanging information in solving a problem. The results of the socialization of the pocket book of research results on the effectiveness of CT scan management of the head with clinical chepalgia were 98% able to increase radiographers' knowledge in the selection of scanogram settings on CT scans of the head with chepalgia able to produce images that enforce dignosa

Abstract

A lead apron is a lead apron designed to protect the body from radiation hazards. The lead apron test is carried out once a year to ensure that it can provide optimal protection when in use, it is necessary to test personal protective equipment. Based on observations, the storage and placement of tin aprons is not in accordance with the rules so that it can reduce its function as personal protective equipment. This study aims to determine whether there is a leak in the lead apron, and to find out whether the lead apron is still suitable for use as personal protective equipment (PPE). This type of quantitative research with experimental methods at the Radiology Installation of RST Dr. Reksodiwiryo Padang on March 31, 2022. The sample in this study was 2 lead aprons, each lead apron is divided into four quadrants, namely the upper right side, upper left side, lower right side and lower left side. Each quadrant was tested with a tube voltage of 70 Kv and a current of 16 mAs. Then made observations and compared with the theory of Lambert and Mc Keon. The results of the study found that there was a leak in the Apron A quadrant 3 with an area of ​​0.75 mm2 and quadrant 4 with an area of ​​0.67 mm2. On Apron B there is a leak in quadrant 4 with an area of ​​0.06 mm2. From the results of the study of lead apron leaks in quadrant 3 and quadrant 4, the quadrant area is a critical area which according to Lambert's theory should not exceed 15 mm2 so that the lead apron under study is still suitable for use as personal protective equipment (PPE).

Abstract

An exposure factor that is too high can result in radiography results that are too black (dark), and an exposure factor that is too low can result in results that are white (bright). Providing an inappropriate exposure factor can prevent the radiograph from providing the best information. When the exposure factor is set properly, radiographic contrast can be maximized, allowing different organs with varying densities to be clearly distinguished from one another in terms of blackness. This kind of research combines an experimental study with quantitative methods. The experimental approach can be understood as a research technique to compare treatments with one another in a controlled environment in order to compare kV fluctuations in the pelvic phantom and achieve the best possible picture quality (contrast). The data processed in the Image J application in the form of a histogram graph is strengthened by data processing using SPSS and the Friedman test. Based on the results of the analysis of the Friedman test, there is an influence, the results obtained at kV 70 show the highest mean rank of 4.57 and in the image J application it shows at kV 70 with graphic results on the histogram of contrast levels which are good, then the radiographic results of the comparison of variations in kV versus contrast in the optimal pelvic phantom are obtained, namely at kV 70.

Abstract

CT Scan is an imaging modality that combines X-rays using the principles of Tomography with a computer as the data processor. Lung Window settings for CT Scan Thorax examination use Window level -500 HU. In the Radiology Installation of Dr. M. Djamil Padang Hospital, CT Scan Thorax examination uses Window level - 600 HU. This study aims to determine which Window level value is better from the variation of Window level values on the lung window - 400 HU, - 500 HU, and - 600 HU on the quality of CT Scan Thorax images with Lung Tumor cases on the Lung Window axial section. The type of research used in this study is quantitative research that is experimental. This research was conducted in the Radiology Installation of Dr. M. Djamil Padang Hospital. The population of this study were patients with CT Scan Thorax examinations with clinical Lung Tumors. The sample in this study amounted to 5 patients with a purposive sampling technique. Then the image results are varied using Window Level value variations - 400 HU, - 500 HU, and - 600 HU and then compared to see which Window Level variation produces optimal image quality. The best value that can display optimal image quality is the window level value of -600 HU because it can show the lung hilus and show pathology in detail and can display a better level of brightness in the image.
