This study performed to ten various ultrasound images taken from the different ultrasound machines to detect the B mode image quality changing various parameters of ultrasound such as frequency, gain & dB. In addition, tissue thermal index (TIS) and mechanical index (MI) have been assessed. ImageJ software used to investigate different pixels and gray values by changing frequency, gain and dB and to acquire histogram, and graphical data, the GetData software was performed. In the case of gray value and pixel distance, some remarkable observations have been obtained by changing the frequency or gain or intensity (dB) and all data has been plotted. The pixel count of liver cirrhosis has been found higher than normal liver parenchyma however significant difference has been obtained for gallbladder stones than normal liver parenchyma. The tissue thermal index (TIS) and mechanical index (MI) were changed during scanning especially colour Doppler scanning depending on the selected area of interest, small selected area showed a higher tissue thermal index than the large selected area however mechanical index was the same.
