OPTIMALIZATION OF WINDOW WIDTH AND WINDOW LEVEL ON LUNG WINDOW FOR ANATOMIC INFORMATION CT SCAN THORAX OF LUNG TUMORS CASE IN RSUD TUGUREJO PROVINCE OF CENTRAL JAVA

Abstract

Background: Settings for Window Width and Window Levels used in CT Scan Thorax tumor cases vary. On Seimens 128 Slice plane there are standard settings for lung window thorax is with Window Width 2200 HU and Window Level-200 HU while according to window width theory is 1000-2000 HU value range and window level-200-800 HU. The purpose of this research is to know the difference of variation setting Window Width and Window Level on Lung Window and Window Width and Window Level optimum in producing anatomical information CT scan thoraks in case of lung tumor.
