Abstract

In medical radiation research, particularly medical physics, patients are represented by phantoms mimicking the human anatomy. Among the most important aspects are shape and size, and Hounsfield unit (HU). Currently there is no established anthropometric data for Indonesians. This study is aimed to present diameter of body size and volume of lung and liver using CT-images. Data of 50 patient CT-images for lung and liver are evaluated, there is using 10 mm axial slice thickness, and the measured dimensions were length of anterior-posterior (AP) and lateral (LAT) for every slices. Organ volumes were measured by generating twodimensional ROI on both lungs and liver, digitally retract the area information, and multiplied slice thickness image to get the total organ volume. From the same images, HU information for lungs and liver were recorded. The result for body size, the averaged diameters of chest for AP's are 18.86 cm and LAT's are 33.66 cm. Meanwhile, the averaged diameters of abdomen are for AP's are 20.01 cm and LAT's are 28.63 cm. Male patients have 43% larger lungs than females, and 16% larger livers than female patients. For HU study, the obtained average HU for lung was -769 HU and liver was +70 HU.
