SaaS for Medical Images: How PostDICOM’s Cloud PACS Brings You the Benefits of Cloud Computing

SaaS for Medical Images Presented by PostDICOM

Medical imaging today largely deals with digital images rather than films. Most modern imaging techniques, such as CT scans, MRI, ultrasound, and PET scans are acquired as digital images on a computer. They then need to be processed, stored, and archived prior to viewing. Digitalization has created a necessity for healthcare workers who use medical imaging to work closely with information technology. This includes using software applications that can help them view, enhance, and edit medical images as well as using applications that help with the storage, archiving, and retrieval of medical image datasets.

Today, several software applications are available on the market for the above purposes, with varying features and prices. Most such software applications are available online or on CDS, which can be downloaded or purchased and installed as standalone applications. Recently, however, the trend is changing and medical imaging software can now be run on a device without actually installing it. This new model is an example of ’Software as a service’ or SaaS.

What exactly is SaaS?

A ‘service’ refers to the process of fulfilling consumer needs and demands by taking on specific tasks. Traditionally, software has been provided as a product. Once software is purchased, the product needs to be loaded on one’s own computer and installed. This is a standalone product, although you can look for updates and install them as and when needed. With the advent of cloud-based computing, which allows users to access anything in the virtual space, it is now possible to provide software ‘as a service’. When software is provided as a service rather than a product, the consumer does not acquire ownership of the software. Instead, consumers subscribe to the use of the software for a fixed period.

How does SaaS work?

With software as a service, the vendor or service provider retains ownership of the software application. The service provider can make the application available to consumers over the internet using cloud computing. Cloud computing is the process of making data services, such as computing power and storage, available to the consumer on demand via the internet. A central server hosts the application and stores data, which can be accessed by users from multiple locations.

To access a software application through SaaS, the consumer can use a standard web browser and go to the webpage where the application is hosted. The consumer may be required to register on the website. While some services may be provided free of cost, most SaaS services work on subscription plans, with advanced features available to consumers after they pay a fee.

What are the advantages of SaaS over traditional software products?

Software as a service has several advantages over software products that need to be installed on premises:

Leveraging the power of SaaS for medical images

Medical imaging technology has embraced the use of software applications for two purposes. Firstly, a special software is needed to view medical images. All medical images are now acquired and stored in the DICOM format. DICOM (Digital Imaging and Communications in Medicine) is a special, high quality standard designed specifically for medical images and regular image viewers cannot open DICOM images. Secondly, the high quality DICOM images need a server that can handle large volumes of data. This server, called a PACS (Picture Archiving and Communications System) server, is usually installed on a computer within the hospital premises.

Software as a service can be used for both DICOM image viewing applications and for storing and archiving medical images. Using SaaS for handling medical images can have several benefits for healthcare facilities. Some of them are explained below:

You do not need to invest in expensive hardware

When you use standalone software, some high-quality applications may have specific system requirements, including a high speed processor, large RAM requirements, and a decent amount of hard disk space. A standalone DICOM viewer requires at least an Intel core i3 processor or higher. Some applications require 8 GB to 16 GB RAM for optimal functioning, and most require advanced graphics chipsets. This might necessitate investment in hardware, which can be expensive. With SaaS, the need for expensive hardware investment is eliminated.

PostDICOM’s free DICOM viewer is SaaS based, and can be accessed through any standard web browser. There is no need for hardware investment, as this web viewer can be used from any existing device that you own, whether it is a smartphone, laptop, or tablet. This means that you can easily skip the cost and hassle of installing and maintaining hardware.

You will eventually run out of storage room on a standalone product

Medical images, whether they are CT, MRI, ultrasound, or PET images, need to be of high quality so that they can allow professionals to make an accurate diagnosis. This means that each image is a big file that can occupy a lot of room: each CT image can be around 520 KB. A single patient scan usually consists of several such images, taken in two to three different sections, and therefore data for one patient alone can take up to 50 MB of storage space.

With a traditional standalone PACS server, you will need ample storage space to store multiple patient scans. The HIPAA regulations mandate that scans need to be archived for a period of at least five years. Eventually, the traditional PACS will run out of room, and your healthcare facility will need to invest in more storage space for future scans.

This problem is easily solved with cloud-based PACS. With patient scans stored and archived on the internet, the question of shrinking storage space does not arise. It is easy to expand cloud-based storage according to the needs of the healthcare facility. For instance, PostDICOM offers cloud storage according to your needs. If your facility is just getting into medical imaging, PostDICOM offers cloud PACS subscription plans. Once your requirements increase, you can upgrade to 500 GB for as low as $149.99 per month. Then, you can expand to as much as 2,000 GB for $499.99 per month. Each of PostDICOM’s paid services comes with a free trial, so that you can test it to your satisfaction before committing to pay.

Software features for medical imaging technology are constantly evolving

Medical imaging technology is constantly evolving, and software applications continually come up with new features. These features include new ways to edit images to improve clarity and aid in medical diagnosis. They can improve diagnostic ability by orienting the physician to patient anatomy through techniques like 3D reconstruction and multiplanar reconstruction. They can also provide additional diagnostic information, such as linear and volumetric measurements, and locating the region of interest through maximum and minimum intensity projections. If you purchase standalone software, you may miss out on new features that are developed after your purchase and installation. What’s more, you might have to hire dedicated professionals just to address any glitches and ensure that all updates are made on time. With SaaS, however, new features are added to the online application as soon as they become available, so you are always using the latest version. This means that when you use PostDICOM’s Cloud PACS or free DICOM viewer, you are automatically using the most updated version with the best features.

Are there any concerns to using SaaS over standalone software products in medical imaging?

Several healthcare facilities still prefer to use standalone software applications because they are not comfortable with the idea of sensitive medical data being stored in an online portal. It is, of course, understandable that healthcare centers find it difficult to deal with the idea that their data is somewhere ‘out there in cyberspace’, rather than right under their nose in the form of films, CDs, or the physical hard disk that houses the PACS. However, storing medical data in a cloud PACS is as safe and secure as storing it in a standalone PACS server. Let us address the two main issues in this regard:
