Update (7/26/2011): Added more proposed updates after feedback from partners.

The HealthVault Medical Image Study data type enables our customers to store medical image studies in HealthVault.

Over last few months, we got feedback from partners and are proposing updates to the type to enable ingestion of larger set of medical image series’, and extend the type to make is more useful for consumer and enterprise usage.

Following are the proposed changes:

Acquisition-datetime


Change the acquisition-datetime element in the medical-image-study-series type from required to optional.

With the above change we will version the type, applications using the older version of this type will receive a sentinel value for all the data which does not have acquisition-datetime.

Application using the newer version of this type will get the value of referring physician in the first medical-image-study-series in the medical-image-study field.
