Automated transfer of study data

Krucom Prefetcher is a solution for automated transfer of DICOM studies between PACS, workstations and other DICOM destinations. Flexible routing capabilities ensure that relevant study data is made accessible at the right place at the right time.

Features

• Studies can automatically be forwarded or pre-fetched to one or more destinations.
  
• Prefetch is triggered by either DICOM Modality Worklist or recently performed studies.
• Scheduling of when pre-fetching or forwarding shall occur.
• Relevant studies are transferred to their correct destination by comparing the DICOM metadata to configurable routing criteria.
• The routing criteria can be tailored and fine-tuned to suite even the most demanding workflow scenarios.
  

Two types of trigger methods are supported:

1. Prefetch: DICOM Modality Worklist is used to trigger the transfers.
   
2. Auto-route: A source archive is queried for new studies and recently performed studies trigger the transfers.
   

Prefetch

Prefetcher automatically retrieves existing studies associated with a patient prior to a scheduled examination. The prefetch is automatically triggered by the scheduled worklist. Using the DICOM Query/Retrieve services, studies can be obtained from practically any DICOM source archive e.g. PACS.

The prefetch functionality consists of four activities:

1. Acquire Worklist

A list of scheduled patients is acquired from the scheduling system e.g. using DICOM Modality Worklist.

2. Query Source Archives

One or more source archives are queried for all studies associated to the scheduled patients. The results are added to a study list.

3. Query Destination Device

Kru Prefetch checks whether any of the listed studies already exist in the destination device. These studies do not need to be transferred and are therefore removed from the study list.

4. Study Transfer

The Query/Retrieve Move service is used to transfer studies from the source archives to the destination device. The study’s scheduled time is used to prioritise the transfer order.

Auto-Route

Prefetcher can automatically route performed studies to another predefined destination.

The auto route functionality is carried out as follows:

1. Query for Performed Studies

A list of performed studies is acquired from the source archive.

2. Query Destination Device

Kru Prefetch checks whether any of the listed studies already exist in the destination device. These studies do not need to be transferred and are therefore removed from the study list.

3. Study Transfer

The Dicom Query/Retrieve Move service is used to transfer studies from the source archives to the destination device. The study’s scheduled time is used to prioritise the transfer order.
