   decoding. Defaults to minimum of `navigator.hardwareConcurrency` and
   what is specified by `maxNumberOfWebWorkers`. Some windows machines require smaller values.
 - `acceptHeader` : accept header to request specific dicom transfer syntax ex : [ 'multipart/related; type=image/jls; q=1', 'multipart/related; type=application/octet-stream; q=0.1' ]
+- `requestTransferSyntaxUID` : Request a specific Tansfer syntax from dicom web server ex: 1.2.840.10008.1.2.4.80  (applyed only if acceptHeader is not set)
 - `omitQuotationForMultipartRequest`: Some servers (e.g., .NET) require the `multipart/related` request to be sent without quotation marks. Defaults to `false`. If your server doesn't require this, then setting this flag to `true` might improve performance (by removing the need for preflight requests). Also note that
 if auth headers are used, a preflight request is required.
 - `maxNumRequests`: The maximum number of requests to allow in parallel. It is an object with keys of `interaction`, `thumbnail`, and `prefetch`. You can specify a specific number for each type.
