Model prediksi ini dibangun dengan pendekatan klasifikasi pada data mining algoritma backpropagation ANN dan random forest . Kategori tingkat kesuksesan dibagi menjadi dua yaitu tidak sukses, sukses. Selanjutnya model dikembangkan berdasarkan variabel-variabel informasi yang ada, dimana dalam tahap. Tahap pertama, 10 variable (9 variabel sebagai input 1 sebagi laebl) ada dataset. Kemudian tahap...

The rate of male breast cancer has increased in recent years, due to the deficiency of preventive examinations (male mammography). Besides, since male breasts are generally smaller than female breasts, it is essential to monitor the doses received by male breasts, as well as those received by close, healthy and critical organs in order to assess the plan used in this kind of treatment. To do th...

In this paper, we present a novel implementation of a dose calculation application, based on the GEANT4 Monte Carlo toolkit. Validation studies were performed with an homogeneous water phantom and an Alderson-Rando anthropomorphic phantom both irradiated with high-energy photon beams produced by a clinical linear accelerator. As input, this tool requires computer tomography images for automatic...

The objective of this study was to assess and compare the organ and effective doses in the knee area resulting from different commercially available multislice computed tomography devices (MSCT), one cone beam computed tomography device (CBCT) and one conventional X-ray radiography device using MOSFET dosemeters and an anthropomorphic RANDO knee phantom. Measurements of the MSCT devices resulte...

OBJECTIVE The present study was aimed at evaluating the effective radiation dose in patients submitted to PET/CT for the diagnosis of mild cognitive impairment. MATERIALS AND METHODS TLD-100 detectors inserted into an Alderson Rando® anthropomorphic phantom were utilized to measure the absorbed dose coming from the CT imaging modality. The anthropomorphic phantoms (male and female adult versi...

This paper presents results of equivalent dose organ determining to both primary beam and scattered radiation in a computed tomography (CT) procedures. All measurements were carried out to abdomen and critical organ (gonads) area. Selected dosimeters showed a standard deviation of 4.1% below to the reference values established by international guide lines. The equivalent dose in gonads was 14.2...
