Breast cancer therapy can be performed using Three-Dimensional Conformal Radiotherapy (3D-CRT) and Intensity Modulated Radiation Therapy (IMRT) techniques. This study aims to compare the effectiveness of IMRT 3D-CRT techniques in terms radiation gain, conformality, homogeneity. The Dose Volume Histogram (DVH) both collected from 10 breast patients was analyzed. Conformity Index (CI) Homogeneity (HI) on planning target volume (PTV), as well dose organs at risk (OAR) according Quantitative...
Abstract This study developed a simple wire phantom and an algorithm to automatically measure the modulation transfer function (MTF) in computed tomography (CT) implemented it evaluate effect of focal spot size reconstruction filter type. The consisted resin cylinder filled with water, tin diameter 0.1 mm positioned along center cylinder. automated MTF used axial image comprised several steps. position region interest (ROI) was determined at image. pixels were then summed y-direction obtain...
This paper presents a characterization of an integrated ozone generator constructed by seven reactors Dielectric Barrier Discharge Plasma (DBDP). DBDP has spiral-cylindrical configuration. Silence plasma produced inside the reactor was generated AC-HV with voltage up to 25 kV and maximum frequency 23 kHz. As source ozone, dry air pumped into controlled valves system flowmeter. We found concentration increased applied voltage, but in contrary, decreased flow rate air. It also that 20 mg/L...
An atmospheric of argon plasma jet was generated by using column dielectric barrier discharge has been investigated. In this study, gas passed through the capillary regulating flow rate gas. This pressure (APPJ) a sinusoidal AC high voltage in range 0.4 kV to 10 and at frequencies 15 kHz 26 kHz. APPJ produced with from 1 litter/min - litters/min. The electric current taken variation each interval litter/min. results show that increase linearly then it trends saturation condition increasing...
Development of ozone technology fish storage system (OTFIS) to maintain the quality has been done. The can be applied in fishing boat, Fish Auction Market, means transport for fish.
