Send DICOM files via HTTPS

DICOM files are typically quite large (in MBs). A better approach would be to upload it to an Amazon S3 bucket and then have your recognition model read it from S3. A bit of wiring will be require on your client side to sequence the multiple API calls together.

See: https://docs.aws.amazon.com/AmazonS3/latest/userguide/PresignedUrlUploadObject.html

As suggested in previous answers I had to use a pre-signed URL to upload large objects. I followed the architecture mentioned in this video.

It is essentially a serverless architecture where a Lambda function (behind and API endpoint) requests for a pre-signed URL, then returns it to the client and the client then uploads his object into an S3 bucket.
