I know atleast a couple of certifications. 1 HL7 Certification 2 Certification on DICOM (Not sure who offers this)
Whether it brings any real value to your resume depends on your company and the line you are into (Functional/Technical)
If you are a functional guy then yes it is obvious that may have to clear certification. If you are a techie then it looks better on your resume and you can crack a job with a top-notch company if they have openings in Healthcare.
