Abstract

Some of the parameters that influence noise level are tube voltage and slice thickness, that can affect image quality and accuracy in diagnosis, with a tolerance limit of the CT number ± 7 HU. 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

Abstract

External radiotheraphy uses either symmetry or asymmetry radiation field. Percentage Depth Dose (PPD) and Dose Profile on either symmetry or asymmetry radiation field is an important parameter in conducting external therapy that is to analyze the result of parameters used for measurement, whether it is adjusted according to the specified tolerance limit. If the field size 10 X 10 cm2 is still in specified tolerance limit or it has been exceeding the limit.The techique used to collect the data was comparing whether dose distribution taken on the surface of either symmetry or asymmetry radiation field with maximum depth gained from Percentage Depth Dose (PPD) measurement and in the depth of 2 cm. By using device Linear Accelerator (LINAC) energy foton 6 and 10 MV in the radiation field with condition field no off-set and off-set 1 cm, off-set 3 cm and off-set 5 cm with Source Surface Distance (SSD) value 100 cm and in radiation field 10 X 10 cm2.The measurement result showed a change depth on Percentage Depth Dose (PPD) value in the off-set of radiation field 5 cm, on both kinds of energy caused by beam hardening, with value of symmetry and flatness 1.43% and 9.28%, for energy 6 MV and 2.2%, 6.59% for energy 10 MV. There was a change in file profile that caused declining value of flatness, and symmetry. Dose distribution because of this asymmetry radiation field should be concerned in clinical for application of asymmetry radiation field usage. Keywords: Percentage Depth Dose (PDD), Profile Dose, Symmetry, Asymmetry, flatness.

Measurement of Computed Tomography Dose Index (CTDI) Distribution in Body Phantom has been done in Dr. Karyadi’s Hospital. The purpose of this research were to find out value of CTDI in the five holes in body phantom and to determine relation between slice thickness and CTDI. This research used CT Dose Profiler in helical CT and CT Dose Profile Analyzer Software. This measurement applied protocol of abdomen with tube voltage 120 kV, time rotation 200 mAs, pitch 1, scan length 160 mm, and scan time 5, 07 second. Measurement was applied variation of detector position in the five holes (center, top perifer, right perifer, bottom perifer, and left perifer) and slice thickness   1 mm, 2 mm, and  3 mm. Average CTDI value in five holes of body phantom has range about 11,97 mGy until         13,17 mGy. There are slight differences among all of five holes. It show that dose ditribution in the center and perofer of body phantom tend to be homogeneous. The fluctuation of CTDI values for 1 mm, 2 mm, and 3 mm slice thickness has nocertain pattern or trend. CTDI values have slight differences among the thickness. The measurement show that   1 mm, 2 mm, and 3 mm slice thickness has 0,5 mGy difference to CTDI value. Keyword: CTDI, five holes, body phantom, slice thickness
