Abstract

Background : Examination of Thorax CT Scan in RSUD Dr.Moewardi is always conducted using bolus triggering technique, where delay of bolus triggering activation done to vary value between 5 - 10 second after contrast media administration using automatic injector with the reason to lessen radiation dose. Purpose of this research is to know influence of  bolus triggering activation delay to radiation dose as well as  to find out  maximal delay value of  bolus triggering activation delay which can be conducted at CT Scan Thorax examination.Methods : This research is experimental method. Data were collected from the observations and the direct examinations on the monitor screen using the CTDIvol dose calculation software. This research is carried out by recording the changes radiation dose value on CTDIvol by changing the value of  bolus triggering activation delay from 0, 2, 4,  6, 8, 10, 12 and 14 second. Data were analyzed using regression test.Results : The result shows that correlation between bolus triggering activation delay towards radiation dose with r = 0,970,  p value < 0,001 and R2 = 0,940. The meaning 94% radiation dose influenced by bolus triggering activation. Delay with regresi equation, Y  = 308,252 - 18,821 DT, showing each every increase of delay bolus triggering activation delay equal to 1 second  will influence to descend dose radiasi equal to 18,821 mGy.Conclusion : Maximum delay to activated bolus triggering is 17 second.

Abstract

Diberikan C[a,b] merupakan koleksi semua fungsi kontinu bernilai real pada selang tertutup [a,b]. C[a,b] merupakan ruang linear atas lapangan real. Dalam tulisan ini dibahas pengertian-pengertian norma, barisan konvergen, terbatas dan monoton, infimum dan supremum dan lain-lain yang semuanya disajikan dalam bahasa fungsi kontinu. Selain itu akan ditunjukkan bahwa barisan yang terbatas dan monoton di dalam ruang fungsi kontinu C[a,b] belum tentu konvergen. Satu sifat yang menjamin sebuah barisan memiliki supremum atau infimum akan dibahas.

Abstract

Background: The main idea of designing an assisting tool for immobilization in pediatric thorax and abdomen examinations is that there are radiographer’ s difficulties while performing radiographs, especially pediatric thorax and abdomen. Aims: This study aims to design of appliance assist for immobilization thorax and abdomen examination on pediatric patients. Methods: This study was an exploratory experiment by designing, applying and testing the construction of an assisting tool for immobilization in thorax and abdomen examination on pediatric patients. The methods used in data collection were interview and observation. Function test results were analyzed based on the check list of the respondents regarding the feasibility of the tool. Results: an assisting tool for immobilization in thorax and abdomen examination on pediatric patients was designed in examination table-shaped made of basic materials such as acrylic, hollow steel and Eser steel plate. Function test on the work of the assisting tool was performed by 6 respondents who applied it to the patient. Based on the function test results, there was of 89,5% respondents who stated that the tool for immobilization in thorax and abdomen examination on pediatric patients could help the performance of the radiographer in positioning and reducing the patient’s movement and there was no artifact in the radiographs. Conclusion: Function test results showed that the tool design could reduce the movement of patients and may replace the function of others to resist the movement of the patient. An assisting tool for immobilization in thorax and abdomen examination on pediatric patients should be improved further especially in choosing the material used, so that the toll will be lighter and can better reduce the patient’s mobility and the size should consider the average height of the pediatric patients.
