Abstract

Gamma rays are ionizing radiation that are useful to kill cancer cells through radiation therapy, but radiation would be dangerous if the user escapes scrutiny. In this case the required dosimeter to detect its existence. Practically daily dose allowed for radiotherapy ranges from 1.8 Gy to 2 Gy therefore needed dosimeter capable of detecting a range of doses. This study has been conducted testing sensitivity to gamma radiation to a solution of CeO2 nanoparticles, each of which is synthesized at a temperature of 400°C with a concentration of 2.5 x 10-4 g / ml. CeO2 nanoparticle solution is then analyzed using a UV-Vis spectrophotometer before and after irradiated. Gamma radiation with an energy of 1.33 MV administered at doses varying from 1 Gy to 3 Gy. The test results in the form of UV-Vis absorbance spectrum CeO2 nanoparticle solution which is used as a reference to determine changes in absorbance (ΔA) and value-G. Absorbance spectrum showed absorbance increased to dosing and a strong absorbance occurs at a wavelength of 297 nm for a solution of CeO2 nanoparticles were synthesized at a temperature of 400°C. Sensitivity solution CeO2 nanoparticles seen from the changes absrobansi and value-G. Gamma radiation dosing provide value change in absorbance of about 1.50 x 10-2 to 2.50 x 10-2 and values around 0.095 molJ-1 to 0,439 molJ-1 to a solution of CeO2 nanoparticles were synthesized at a temperature of 400°C.  These values indicate that the solution of CeO2 nanoparticles have a sensitivity to gamma radiation.

Abstract

The measurements of CTDI have been done as the method used to measure of dose in CT scans. The Measurement method is CTDI air method. Measuremeans of CTDI air using the CT dose profiler was placed in the center of the gantry rotation using tube voltage variations (80 kVp, 100 kVp, 120 kVp and 140 kVp), current time variations (100 mAs, 200 mAs, 300 mAs and 370 mAs) and pitch variations (0,75, 1, 1,25 and 1,5). The results of measurements  tube voltage variations in 370 mAs, pitch 1 and collimation 5 mm were 28,8-105 mGy, current time variations in tube voltage120 kVp, pitch 1 and collimation 5 mm were 19,7-73 mGy and Pitch variation in tube voltage 120 kVp, effective current time 370 mAseff, and collimation 5 mm were 55,9-116 mGy. The measurement results showed that greater the tube voltage, current time and pitch are used then the resulting CTDI air gets greater. The smaller tube voltage, current time and pitch are used then the resulting CTDI air gets smaller. FWHM and  geometric effisiency value of tube voltage variation were 6,2-6,37 mm and 68,40%-71,30%, current time variation were 6,17-6,27 mm and 69,5%-72,5% and pitch variation were 6,19-6,51 mm and 69,2%-71,4%. FWHM values of the three variations were larger than the width of collimation because the penumbra effect and geometric effisiency values were still within tolerance limits of 55%-75%. Keywords: CT dose profiler, CTDI air, FWHM, geometric effisiency

Abstract

A study has been conducted to analyze the dose parameters are CTDI100, CTDIw, CTDIvol, DLP and dose profiles by using standard phantom (150 mm) and non-standard phantom (300 mm). This research utilized an abdomen phantom, CT Dose Profiler and software Ocean. Exposure factors in this study in accordance with the conditions of the abdomen routinely performed at the Hospital of the tube voltage 120 kV, current 350 mA, collimation 40 mm, and pitch 1.375. The detector is placed in the center of the phantom and scanning with variation of scan-length 150 mm and 200 mm in the standard phantom (150 mm) and the variation of the scan-length 150 mm, 200 mm, 300 mm in non-standard phantom (300 mm). The result obtained is the parameter dose values in the non-standard phantom (300 mm) are higher than standard phantom (150 mm). At a scan length of 150 mm, the difference in value is 4.825% CTDI100, CTDIw 4.858%, 4.823% CTDIvol, and DLP 4.820%. Meanwhile, the difference in the value of the parameter dose at the scan length of 200 mm is CTDI100 3.477%, 3.494% CTDIw, CTDIvol 3.510%, and DLP 3.512%. The resulting dose profile has similar peak-dose value but have a different width so that the dose profile in non- standard phantom (300 mm) is wider and having higher FWHM value than the standard phantom (150 mm) because non-standard phantom has longer scan length that lead to excessively scattered radiation.Keywords: CT Dose Profiler, dose profiles, scan length, standard phantom, non- standard phantom, CTDI100, CTDIw, CTDIvol, DLP, FWHM.

Abstract

Excess total blood cholesterol can lead to heart vessel disorders, stroke and the most fatal can result in death. While testing the cholesterol levels in the blood at this time still use the invasive technique that the patient's blood is taken by using a syringe. This is one of the obstacles / causes of some patients are reluctant to check blood cholesterol. One of the health technologies to detect blood cholesterol in non-invasive is by utilizing the absorption of near infrared ray (NIR) and laser. The change in the physical properties of the resistance shows the chemical content of different solutions. Preparation of non-invasive blood cholesterol gauge by utilizing oxymeter sensor capable of producing voltage changes in various liquid medium and Atmega 8535 microcontroller as a minimum system in controlling output value in digital data form. The system or equipment to be fabricated in this study is a non-invasive method (without injuring the patient's body while taking blood samples) to determine the blood cholesterol content by utilizing the physical properties of laser absorption or NIR sensors on various blood cholesterol levels. From the research results have been made series of sensor interfaces and serial data communications are displayed digitally. The test results show that the equipment made has shown good performance but still limited its performance test. The results of the research will be developed into a national program of providing cheap, non-invasive portable and movable health test kits. Keywords: Heart Disease, Blood Cholesterol, NIR, Laser, Microcontroller.
