Abstract

The use of scaning protocol with high dose and low dose in CT scan would affect the quality of the images obtained. Because of the importance of good radiographic images in the enforcement of proper patient diagnosis, then performed an analysis of the image quality obtained from both protocols.Image quality assessment of high-dose protocols and low doses for routine head examinations carried out through performance analysis using the AAPM CT phantom performance, comparison of the value of GM conspicuity and Contrast to Noise Ratio (CNR) of the image of the patient as well as comparison of gray scale images through image histogram comparison phantom homogeneous and patient image histogram.Results of analysis of the performance of the two protocols by assessing the accuracy of the CT number, noise, low contrast resolution and spatial resolution showed that high-dose protocol has better performance than low-dose protocol. Image with high-dose protocol has an average GM conspicuity of 0.3863 and CNR 7.0105, while the image with a low dose of 0.4144 and 6.2725 at CNR. Comparison of gray scale image of the protocol through the image histogram comparison homogeneous phantom and patient image shows that the image of a low-dose protocol has variation of intensity gray value that is wider than high-dose protocol.Keywords: Computed Tomography, scaning protocol, image quality, GM conspicuity, CNR

Research carried out by using detector CC TNC / 9770 and detector CC TNC / 9776 with variety on the position of the detector on axes x1, y1, x2 and y2, and  wide field irradiation of 10 x 10 cm2 at SSD 100 cm. On this research for PDD  scanning, position’s detector coincide to relative dose and at any depth. The largest is in position y1 with measurement dose  100.06 %. So position y1 used as reference position for measurement of stem effect. For PDD  scanning ratio stem effect on the position of y2, x2, and x1 are 0.260521 %, 0.049995 % and 0.140112 %. So the effective position’s detector for PDD scanning is position x2 with the ratio of the smallest stem effects is 0.049995 %. For crossline scanning, position x1 used to an form position for measurement of stem effect because have the largest measurement of relative dose that is 100.04 %. For crossline scanning ratio stem effect on the position of y1, x2 and y2 are 0.080032 %, 0.080032 %  dan 0.240481 %. In position y1 and x2 have a same of ratio stem effect, but based on distribution of measurement dose in the beginning and the end scanning, effective position of the detector for crossline scanning in position y1. For inline scanning, position x1 used as reference position for measurement of stem effect because have the largest measurement of relative dose that is 100.00 %. So position y1 used as reference position for measurement of stem effect. For inline scanning ratio stem effect on the position of y2, x2, and x1 are 0.070049 %, 0.020004 %  and 0.010001 %.

Abstract

Percentage depth dose at the Linac has not reached 100% on the surface and should be made an effort to treat skin cancer or skin cancer that is closer to the surface so that the maximum dose obtained cancer, one of the efforts is the use of bolus. The research reviewer feasibility of using polydimethylsiloxane as materials bolus in radiotherapy. Bolus made with a thickness of 3, 6, 9 and 12 mm with a size of 11x11 cm2, tomography image is then taken using a CT-scan to determine the CT-number that is used to calculate the density and compared to the density of mass and volume ratio. Bolus irradiated with electron 8 MeV at 100 MU for 60 seconds and measured the dose absorbed at a depth of 0; 0.5; 1.0; 1.5; 2.0 and 2.5 cm. The result of the calculation using the CT-number density is 1.24 ± 0.02 g /cm3 and the density calculation results using the ratio of the mass and volume was 1.25 ± 0.01 g / cm. Absorbed dose at the surface with the use of a bolus of 3, 6, 9 and 12 mm by 82.09%; 85.13%, 89.12% and 93.48%, while without using bolus which showed the value of absorbed dose amounted to 78.23%. Absorbed dose at a depth of 2.5 cm with the use of a bolus of 3, 6, 9 and 12 mm by 79.84%; 49.26%; 34.52% and 17.80%, while without using bolus which showed the value of absorbed dose amounted to 88.68%.These results show the density of the bolus polydimethyl siloxane has similarities with soft tissue density and may increase the dose of the surface and reduce the dose depth so polydimethyl siloxane may be one of the reference materials that can be used as a bolus in radiotherapy.

The objective of this study is to define the noise level on the tube voltage 0f 120 kV and 135 kV with slice thickness variations. The measurement used water phantom scanning of head with tube voltage 120 kV, 135 kV and slice thickness 2, 3, 5, 7 and 10 mm. water phantom scanning of the abdomen with tube voltage 120 kV and slice thickness 3, 5, 7, 10 and 20 mm. Noise level got from central ROI area phantom. The high tube voltage and increasing the slice thickness, that the noise level decreases because the x-ray tube produced high x-rays energy and high photons penetrating to tissues. Noise levels are good when using eksposure parameters are current-time and tube voltage : 225 mAs, 135 kV with a slice thickness of 10 mm is 0.47 % for the head and 375 mAs, 120 kV with a slice thickness 3 mm is 0.45 % for the abdomen.Keywords: Noise, Slice thickness,Phantom, CT number

Abstract

During radiotherapy treatment, critical organs are shielded using cerrobend blocks. The objective of this study was to define the minimal thickness of cerrobend blocks so that the relative absorbed dose in target less than 5%. All measurements were performed using linac Siemens/Primus Mclass 5633. Phantom relative absorbed dose were measured for square field 10 x 10 cm2. The thickness of cerrobend blocks were 2, 4, 6, 8 and 10 mm. The measurements in water were performed using compact chamber fitted with acrylic build up caps.The minimal thickness of cerrobend blocks for 5, 10 and 14 MeV electron beams are 2, 4 and 6 mm, respectively. The relative absorbed dose for phantom’s surface, maximum depth and x-ray tail using those blocks are 0.12%, 0.16%, 0.21%, 2.18%, 1.56%, 1.16%, 2.92%, 2.47% dan 1.70%.The relative absorbed dose decreases with the increasing of cerrobend block  thickness and phantom depth. Therefore, if cerrobend blocks are used to protect critical organs, the thickness should be taken into account accurately.Keywords: cerrobend blocks, relative absorbed dose, electron beams

Research of the natural radionuclide distribution of soil, water and plant samples around Rembang Coal Fired Power Plant (CFPP) has been done with the purpose of the study is to know the activity concentration of natural radionuclide, the pattern of distribution of environtment radioactivity around Rembang CFPP with soil, water and plant samples and compare the activity concentration of natural radionuclide around Rembang CFPP with Environmental Radioactivity Limit Values (ERLV) which is listed on the Perka Bapeten No 16 of 2013 about Safety Radiation in Storage of Technologically Enhanched Naturally Occuring Radioactivity Material. Sample analysis method using gamma spectrometry with HPGe detector and Maestro 2 software is based on SNI 1070.3-2009. The calculated concentration of natural radionuclide activity 226Ra, 228Ra, 232Th dan 40K in soil sample is (8.17×10-3 ± 2.33×10-4; 9.99×10-3 ± 1.69×10-4; 7.84×10-3 ± 2.78×10-4; 4.46×10-2 ± 6.78×10-4) Bq/g. Water sample (3.07×10-3 ± 4.05×10-4; 3.59×10-3 ± 3.22×10-4; 6.59×10-4 ± 5.59×10-5; 2.82×10-2 ± 1.93×10-3) Bq/L.

The distribution pattern of the concentration of natural radionuclide activity that is formed that is in the soil sample has the distribution pattern of the distance from CFPP Rembang the bigger concentration activity. Furthermore, in water and plant samples the distribution pattern tends to lead to a location close to the CFPP that has a bigger concentration of activity. Comparison the concentration of natural radionuclide activity with Environmental Radioactivity Limit Values (ERLV) it was found that the overall concentration of natural radionuclide activity in soil, water or plant samples at each sampling site still did not exceed the Environmental Boundary Limit Radioactivity (ERLV) that defined by Perka Bapeten No 16 of 2013 about Safety Radiation in Storage of Technologically Enhanched Naturally Occuring Radioactivity Material.Keywords: Natural radionuclide, environment sample, Rembang CFPP, gamma spectrometry, radioactivity, distribution.
