Description
Phantom replacement of femur based on human CaCO3, CaCl, NaCl, KOH + white cement successfully made. Phantom replacement of the femur in humans is made with 3 variants of composition (x = 0.3 and y = 0.67, x = 0.34 and y = 0.63, and x = 0.4 and y = 0.57) namely x is CaCO3 and y is white cement. Thigh replacement phantom was tested using the GE / Optima 660 brand CT-SCAN with 3 potential different variations namely 80 kV, 100 kV, and 120 kV to see Hounsfield units (HU) in the test sample. Through CT-SCAN test, the highest HU is 2016, which is found in substitute phantom x = 0.3 and y = 0.67 with a potential difference of 80 kV and the lowest HU is 904 found in the replacement phantom variation x = 0.4 and y = 0.57 with 120 kV potential difference, while HU bone in general is +/- 1000.
