Cloud PACS and on-premises PACS have different operation methods, so the usage payment method and benefits are different. Take a look at the descriptions below and consider which PACS system is right for your hospital or institution size.

​

​How is the operation different?

In the installed PACS, all hardware and software for storing medical data are installed inside hospitals and institutions. Patient digital images and related data generated by the imaging equipment are directly stored in storage through an internal server, and patient data can be viewed through the PACS software on a computer or workstation that has access to the installed server.

On the other hand, cloud PACS stores patient digital images and related data generated by imaging equipment on a remote server over the Internet. You can also log in to the PACS application through a web browser to view stored patient data.

​

Who should do the maintenance?

Installation-type PACS requires direct system control and management with ownership of the infrastructure as all hardware and software for storing medical data are installed inside the institution. Occasionally, depending on the increase in medical data, it may be necessary to check whether the server capacity is sufficient and to add additional storage. Therefore, large-scale hospitals often use installed PACS, and IT staff are resident for maintenance.

In the case of cloud PACS, a part of the provider's infrastructure, such as servers, storage, and equipment implemented in the cloud, is provided in a form that hospitals and institutions borrow for the purpose of storing, managing, and inquiring about medical data. Responsible for maintenance.

​

What are the pros and cons of each system in terms of cost?

Installed PACS has a higher up-front cost because you have to cover the hardware and software costs, but the average monthly cost tends to be lower after the higher up-front costs for infrastructure equipment. In addition, IT staff to maintain the infrastructure such as server and storage cost management and equipment upgrades are required  It is an appropriate PACS system when a large hospital with an internal computer room wants to manage the system directly.

Cloud PACS is a form of subscribing to multiple systems such as server, storage, and equipment as one product, so the initial hardware burden is reduced, and there is no need for a separate IT staff to reside inside the hospital for system maintenance. If the medical data storage capacity increases depending on the hospital operation situation, you can immediately secure additional capacity by applying to the PACS supplier for storage space extension.

​

What are the pros and cons of each system?

The installed PACS can be equipped with an independent PACS system in the hospital. Only dedicated computers or workstations within the hospital can access the PACS, limiting where data can be accessed.  

​Cloud PACS allows you to store, manage, and search medical data through a web browser using the Internet if you have access to medical data. Convenient to work remotely and to transfer medical data to outside-hospital users with access rights.

​

What security are you following to protect your medical data?

​Installed PACS' infrastructure is owned by the hospital, so the hospital and facility are responsible for implementing and managing the security of all medical data files, images and information. For example, it is necessary to comply with the security in line with the legal level of Article 23 2 of the Medical Act (standardization of electronic medical records, etc.).

​For cloud PACS, it is important to ensure that the public cloud products on which the PACS vendor's infrastructure is implemented have appropriate security measures in place.
