Abstract

The study on prediction of 2D isodose curves for atbitrary field size has been done. Isodose curve is very useful for plannning and evaluation of doses received by patients in the radiotherapy treatment. The percentage depth dose (PDD) and dose profiles data for standard field size (square) were obtained from measurements in the Kensaras hospital, Semarang Regency. Dose profiles were taken at a depth of 1.5 cm and a radiation source to skin distance (SSD) of 100 cm. The calculation of PDD data in any field size uses linear interpolation method. While the calculation of the dose profile curve uses the widening, narrowing and weighting interpolation method. Firstly, the calculation of PDD and dose profile for standard field sizes of 3x3, 10x10, 15x15 and 20x20 cm2 were carried out and the results were compared to the measurements. Secondly, the PDD and dose profile for arbitrary field sizes 7x7 dan 13x13 cm2 were calculated. After that, the isodose curves for arbitrary field sizes were generated. The results showed that PDD curves of standard field sizes have maximum deviation values < 5% compared to the measurements. While the dose profile curves for field sizes up from 5x5 cm2 have maximum deviation values approximately 5% which was less than measurement. The profile curve of field size of 3x3 cm2 has maximum deviation value >5%. These results showed that our proposed algorithm was relatively valid. In this study, the PDD, dose profile and isodose curves of arbitrary field sizes 7x7cm2 and 13x13 cm2 were succesfully generated.

Abstract

ABSTRACT---Tuberculosis (TB) is an infectious disease caused by the bacteria mycobacterium tuberculosis. TB is the number one killer among infectious diseases, and even Indonesia occupies the fifth largest country in the world in this disease problem. Detection of TB disease through clinical symptoms, laboratory tests and thoracic imaging (lung) with x-ray. The research was conducted to determine the histogram and the average value of gray scale image of the thoracic patients suffering from TB and who is not. By knowing the value of the histogram and the mean gray scale this can later be used as additional instructions for medical personnel to diagnose, i.e. to determine whether the patient has TB or not. In this research, the exposure factors was carried out with a tube voltage of 55 kV, tube current 200 mA and time 0.08 s, using of the Computed Radiography (CR). Histogram analysis performed on the Region Of Interest (ROI) that is at the apex of the lung and superior lung lobes contained patches of gloom on the image of the thorax. It was obtained that the image histogram from TB patients shifted to the right or the gray scale pixel values have a higher (brighter). The average value of pixel gray scale image of the patient suffering from tuberculosis at 13,3 and for patients who are suffering from TB at 61,6.Key words: thoracic imaging, Tuberculosis, histogram ABSTRAK---Penyakit Tuberculosis (TB) merupakan suatu penyakit menular yang disebabkan oleh bakteri mycobacterium tuberculosis.

Abstract

An evaluation of the value of the slice thickness due to changes in tube voltage and tube current on the CT scan have been performed. The evaluation is done by making images using CT performance test phantom. Testing is done by performing three scanning on each slice. Exposure factors used were 120 kVp-60 mA, 160 mA 120-kVp, 140-kVp 60 mA, and 140 kVp 160 mA. Nominal beam width were 2 mm, 3 mm, 5 mm, 7 mm, and 10 mm. Once the axial image was obtained (on the area for slice thickness determination),  then calculated the average CT number on the region of interest (ROI). After it was made graphs to determine the value of FWHM which indicates the magnitude of the thickness of the slice. From the test results obtained that changes in tube voltage and tube current does not affect the value of the thickness of the slice. Also found that the value of slice thickness for each thickness, greater than the nominal beam width.   Keywords: Phantom CT Performance Test, Slice Thickness, CT-Scan    Telah dilakukan evaluasi terhadap nilai slice thickness terhadap perubahan tegangan tabung dan arus tabung pada pesawat CT scan.

Abstract

The curve of 2D isodose is used to determine the dose distribution in patient treated by radiotherapy. Therefore, isodose curve is very useful for planning and evaluating of the dose received by the patient. Correction of 2D isodose curve for sloping surface is very important due to the skin of patient is not flat. In this study, the correction of isodose curve was calculated using tissue air ratio (TAR) method for radiation field size of 10x10 cm2. The correction factor was obtained by comparison of TAR value for effective depth and TAR value for total depth. The correction factor then was multiplied to isodose curve for flat surface. In this study, the software for calculating the automated correction factor due to sloping of patient surface has been successfully developed. It was found that if the sloping of patient surface increases then the corrected isodose curve increases. Key wods: 2D isodose curve, tissue air ratio (TAR), correction factor, sloping patient surface.

Abstract

The mammography use the specific x-ray energy. At high x-ray energies (>35 keV) the subject contrast between the normal and malignant tissues in the breast is poor, at very low x-ray energies (10-15 keV) the contrast is highest, however the high absorption result in a high tissue dose. To achieve to good result must be used the optimal energy, that could be achieved by using specific x-ray target and additional filter materials to generate characteristic x-ray of the desired energy. This research was aimed to evaluate the influence of target-additional filter combination and filter thickness to the x-ray energy spectrum. The research was conducted by Monte Carlo simulation using EGSnrc program. The model of mammography tube was designed by BEAMnrc program, and phase space file was resulted by BEAMnrc was analyzed by BEAMDP. The tube x-ray contained of target and additional filter from molybdenum (Mo) and rhodium (Rh) material, window from berrylium, and collimator from Pb. Target-additional filter combination were Mo-Mo, Mo-Rh, Rh-Rh and Rh-Mo.  Variation of additional filter thickness that be used are 0,001 mm; 0,03 mm; and 0,05 mm. The results of the simulation indicated that an x-ray consist of bremmstrahlung and characteristic. X-ray spectrum were produced by Mo target had characteristic x-ray energy 17 keV and 19 keV, and Rh target had characteristic energy 20 keV and 23 keV. Target-additional filter combination that allowed are Mo-Mo, Mo-Rh, and Rh-Rh combination. Rh-Mo combination could not be used, because Mo filter would attenuated x-ray characteristic energy. For the Mo-Mo and Rh-Rh, the thicker the additional filter then the x-ray spectrum obtained has a more narrow, but the reduced intensity of the x-ray bremmstrahlung and characteristic.   Keywords: target-filter combination, x-ray spectrum, mammography, EGSnrc.

Abstract

Mammography is a radiographic examination to detect breast cancer earlier. However, the usage of radiation with low kVp can cause high dose and this becomes the reason why monitoring the dosage during the mammography process is an important thing to do. One of the techniques to monitor the radiation level is done based on the Entrance Skin Exposure (ESE) value. This research was aimed to determine the ESE value using molybdenum (Mo) and rhodium (Rh) as the filter at Mammomat 1000 mammographics system.The research was started by measuring the consistency of the X-ray tube voltage (kVp ). After that, the ESE value at the target/filter Mo/Mo and Mo/Rh was measured using a Barracuda Multi Purpose Detector (MPD). The tube voltage during the research was 26, 28, and 30 kVp with fixed electrical current-time 100 mAs. The result shows that ESE value resulted at the target/filter Mo/Mo and Mo/Rh is tolerable, except at tube voltage 30 kVp with target/filter Mo/Mo. The comparison of ESE value shows that Mo/Rh has lower ESE value than Mo/Mo.   Keywords: Entrance Skin Exposure (ESE), mammography, Barracuda Multi Purpose Detector (MPD)    Pemeriksaan mammografi merupakan tindakan efektif dalam mendeteksi adanya kanker payudara sejak dini.
