Notification about Worklist Availability

• We proposed a push model of MWL at the last
  meeting of DSC in Munich. But, it was rejected.
• We still need a mechanism that can trigger a
  modality to pull a specific worklist.
• Poling is one of the solutions, but it may cause
  the network congestion.
• An RIS terminal is usually put closely by the
  modality.

Japanese government will modify a rule on drugs
and medical equipment

• Ministry of Health, Welfare, and Labor will
  modify a rule that regulate the use of drugs and
  medical equipment.
• They updated the list of medical devices. A
  general purpose image processing workstation is
  now included in the list.
• The workstation may be classified as Class 2
  devices and then, vendors will be required to
  improve their organizations.

Japanese government will modify a rule on drugs
and medical equipment-to be continued

• Requirements
• Vendors must be authorized to sell the
  workstations and prepare experienced people to
  sell them.
• Manufacturers must be authorized to develop and
  manufacture those devices and form a division
  that is responsible to the quality of the
  devices.
• This is the result from global harmonization. FDA
  already has such a rule.
