The setting parameters of ultrasound scanner give influences to change of image. Sonographers have used a Matlab program to make Low Contrast Sensitivity(LCS) value and compared original images in order to evaluate the use of the supersonic diagnosis machinery. We confirmed the change of image in Grayscale values using Photoshop program. Experiment equipment of our research used A Medison Accuvix V10, A Multi-Tissue Ultrasound Phantom(040 GSE) of CHRIS Company, A Adobe Photoshop CS4 Program, A Convex Probe, A USB memory stick, A Probe Fixation Equipment. The method used Gain, Dynamic Range(DR) of the setting parameters of ultrasound scanner and researched Gain and DR was set to 10 dB. We changed the different settings to see the changes of images using Grayscale values of a Photoshop program about tissue images of a phantom. This study evaluated DR and Gain whether it is an image controller to get the optimum contrast to produce an image to see the how effect on the images. We did not use Gateway in supersonic diagnosis machinery. We can easily open to open the files through Photoshop program before we get Digital Imaging and Communications in Medicine(DICOM) files use USB memory stick in supersonic diagnosis machinery. When we diagnosed the lesion of the patient with ultrasound, the contrast and the Gray scale value of image are very important. In this research, we determined the optimum setting parameters that provided useful information to diagnose disease and evaluated the change of improved images.

문제 정의
Also there were when the DR was 60 dB, the Gain was 60 dB, when the DR was 70 dB, the Gain was 60 dB, when the DR was 80 dB, the Gain was 60 dB, and when the DR was 90 dB, the Gain was 70 dB. Depends on the sonographer and use of equipment of ultrasound, in this study will be provided useful information that for the setting of the scanning parameter of diagnostic ultrasound.
To get a best images, we experiment the image change according to the parameter and record images pixel value using the Photoshop CS 4 Program that ordinary people can use easily. This is the experiment to find out the image change according to the parameter and to verify the specific image change. Therefore, we were obtained the best image of the scan and there will be distinguished the diagnostic diseases from noraml.
This study is to investigate how affect the image caused by DR and Gain. Fixed DR, the image was brighter with Gain which are increased by every 10 dB(Table 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13).
Contrast and gray scale are very important for the diagnosis of the patient using ultrasound. This study was to investigate how affect the image caused by DR and Gain using ultrasound parameters. and it is anticipated that it will produce the useful information to set up the best variable parameters in clinical setting.
대상 데이터
In the present study, we used the Medison Accuvix V10. The Phantom we used is MultiTissue Ultrasound Phantom(040 GSE, CIRS, USA). The probe we used C2-5 EL(C2-5 EL, Medison, Korea), Convex Probe.
성능/효과
In this study result showed that bigger the value of grey scale was greater contrast with differences of cyst in the parenchyma tissue. and the best setting of gray scale were when the DR was 50 dB, the suitable Gain was 50 dB.
4). Therefore, best setting were when the DR was 50 dB, the suitable Gain was 50 dB, when the DR was 60 dB, the Gain was 60 dB, when the DR was 70 dB, the Gain was 60 dB, when the DR was 80 dB, the Gain was 60 dB, and when the DR was 90 dB, the Gain was 70 dB. And this graph also changed from curved graph to straight graph that in the parenchyma, the distinction of the cyst were less influenced with gain by the increasing DR(Fig.

and it is anticipated that it will produce the useful information to set up the best variable parameters in clinical setting. Also, many ultrasound companies setting are different, so that further the experiment will be necessary for best parameter for the each equipement.
