Thank you for posting your inquiry on our forums.
I would like to offer a word of caution to you, however, on your use of the ImageServer Alpha version.
The Alpha version was intended to be a "preview" of later, commercial products and not intended to be deployed in a production environment, as it seems you are now doing. Not only that, the Community Edition products are meant as reference, education and research tools, not to be used in clinical settings, as the Community Edition products are not included in our FDA clearance.
Thus, to use the Community Edition products in a clinical setting greatly exposes you to medicolegal liability.
Please exercise proper discretion in the appropriate use of these software applications.
