1.       Opening

1.1.    The conference was called to order at 2:00 p.m. US ET.

1.2.    The antitrust rules were reviewed, and DICOM patent policy as well.

1.3.    The agenda was approved.

2.       Discussion of incorporating AI into workflows using standards

The goal of this call was to discuss further AI topics.

Big question: Does this topic belong to WG-20 II or WG-23 or IHE? We will know more information after the upcoming Sept 10th meeting.

Google Docs are created below:

Workflow 1 – Reading Workflow:

Workflow 2 - Image Generation Workflow:

Potential Future Work:

Workflow 1: Passing Discrete Data in the Reading Workflow

A radiologist opens a study for a Head CT. An AI algorithm runs to detect the presence of a midline shift and the measurement of the shift. This information is passed to the PACS and the reporting system. Using the PACS and reporting system the user finishes the study and signs the report. The discrete midline shift measurements along with the report are sent to the patient records.

Workflow 2: Passing Discrete Data in the Image Generation Workflow

A patient has a chest x-ray performed, after the chest x-ray is performed, an AI algorithm runs to detect a pneumothorax. The discrete pneumothorax is sent to the worklist for prioritization and to the PACS for storage.
