If a study contains many number instances e.g., a CT exam contains more than 1,000 images, sending WADO requests will be time out. It needs to redesign the retrieving mechanism to avoid this situation. For example, mixing asynchronous and synchronous HTTP requests may be a solution to avoid request large number of HTTP requests in a short period. The other method is to re-send a WADO request if a timeout happened.
