Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
\- The investigators aim to evaluate the feasibility of remote interpretation for ultrasound images using a smartphone based realtime image transmission system.
Methods
A total of 100 echocardiography examinations; 50 showed the ejection fraction above 50% and remaining 50 cases showed the ejection fraction under 50%, and 100 abdominal ultrasound images; 50 had signs of acute appendicitis and the other 50 had no findings of appendicitis will be consecutively selected. The 12 raters review these original images using an LCD monitor of the ultrasound machine and also an iPhone which is connected to the ultrasound machine via remote image transmission system (CubeView, Alpinion medical system, Seoul, Korea), evaluating left ventricular systolic function (for echocardiography) by measuring the ejection fraction and grading the probability of presence of acute appendicitis on each examination by a five Likert scale.
The sensitivity and specificity between two devices will be compared and the diagnostic performance between two devices will be also compared. The image quality between two devices will be measured using the double stimulation impairment scale (DSIS)

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The raters in group one review the echocardiographies examinations numbered from one to 50 using LCD monitor of ultrasound machine and review the remaining 50 examinations numbered from 51 to 100 using iPhone with CubeView at their first visit The other group firstly review echocardiography numbered from one to 50 using iPhone with CubeView and 51 to 100 with the LCD monitor.
They visit twice with an interval of four weeks and review the echocardiography examinations using revered devices at each session. They also review abdominal ultrasound images on the same plan as reviewing echocardiography.
When they review the echocardiography, the raters measure the ejection fraction by visual estimation (1=obviously normal EF, 2 = probably normal EF, 3 = unsure, 4 = probably reduced EF, 5 = obviously reduced EF). In cate of d the abdominal ultrasound, they are instructed to rate the likelihood of the presence or absence of appendicitis in each case using a five-Likert scale (1 = obvious no appendicitis, 2 = unlikely appendicitis, 3 = unsure, 4 = likely appendicitis, 5 = obvious appendicitis).
