Management of Acquisition Protocols

From IHE Wiki

Summary

Management of Acquisition Protocols (MAP) supports the collection of scan protocols from acquisition modalities, their review on a protocol manager and re-distribution to modalities. Protocol managers are permitted to edit attributes marked safe by the creating modality. Such attributes will likely include protocol names, dose notification thresholds, and series names for generated images.

Benefits

Improve Quality of Care

  • Good, consistent image quality depends on good protocols, used consistently
  • MAP helps monitor protocols in use (and detect variants)
  • MAP helps distribute preferred, consistent protocols

Improve Workflow Efficiency

  • Hanging Protocols, Image Processing, Reporting Workflow, etc. depend on consistent series names, procedure codes, etc.
  • MAP helps create and manage such consistency

Manage Dose

  • Managing dose depends on managing protocols
  • Variations in protocols results in variations in dose

Support Analytics

  • Summarizing data depends on consistent tagging
  • Determining your average throughput for each type of procedure depends on good naming and coding

Details

The transactions are based on storage, query and retrieval of DICOM® objects containing scan procedure protocols and protocol approvals. Although the profile is agnostic to the type of modality, as of 2018 DICOM has published the specification for CT Protocol Storage. DICOM work is in progress to support XA and MR protocols. When those are published they will also be incorporated into the Profile.

Systems Affected

  • Modalities may send protocols for review and receive distributed protocols and approvals.
  • PACS systems may store sets protocols
  • Protocol management workstations may retrieve, review, approve and make minor edits to protocols.

Profile Status: Trial Implementation

Document: IHE Management of Acquisition Protocols (MAP) Profile - Supplement Document


Underlying Standards:

Sample RFP Language

Although several patterns of implementation of the MAP Profile are possible, IHE expects that:

  • the Acquisition Modality Actor will be implemented in scanners,
  • the Protocol Archive Actor will be implemented in PACS, VNAs and/or Protocol workstations, and
  • the Protocol Manager Actor will be implemented in Protocol workstations, Dose workstations, and/or RIS systems

Questions to ask vendors:

  • Do you plan to implement IHE’s Management of Acquisition Protocols (MAP) profile? If so, when?
  • Do you plan to test your implementation of MAP at an upcoming IHE Connectathon? If so, when?

Example RFP Requirements:

  • The CT scanner shall support the IHE Management of Acquisition Protocols (MAP) profile as the Acquisition Modality actor.
  • The VNA shall support the IHE Management of Acquisition Protocols (MAP) profile as the Protocol Archive actor.
  • The protocol management workstation shall support the IHE Management of Acquisition Protocols (MAP) profile as the Protocol Manager actor.

Related Profiles

  • Scheduled Workflow [SWF.b] has an Assisted-Protocol Setting Option that would benefit from management of protocol labels.
  • Portable Data for Imaging [PDI] could be used to export/import DICOM protocol instances to media for sharing with another facility or organization. (e.g., protocols for multiple models in a given clinical trial, reference protocols for a particular diagnostic task, or a full backup catalog of protocols)
  • Radiation Exposure Monitoring [REM] could be used on the protocol manager to coordinate a dose reduction program with protocol management.
