It can be safely said that the healthcare services industry is in a state of flux like never before. Reform initiatives driving the mandate to create interoperability are not in any way exempting medical imaging. As such, we are experiencing a rapidly evolving technology shift that is creating a great deal of confusion in the market. In part, this trend is fueled by the shifting sands of healthcare delivery in that nobody can clearly articulate what healthcare is going to look like in the next decade. So, in response we seem to be hedging our bet towards systems’ flexibility when we should be focusing our attention on systems’ standards, or both.
Today we live in a new world where selecting imaging technology in component parts (deconstructed) has gained some traction and begun to chip away market share from the more traditionally packaged systems. The determination to go either way is one that requires a good deal of thought and a better than average understanding of imaging technology and workflow.
What does deconstruction actually mean?

- To break down into components; dismantle
It is imperative to define what exactly deconstruction means in order to assist the reader in determining the contemporary market interpretation. It is possible today to completely dismantle a PACS into separate and independent components only to glue them together again in order to match the functionality of a constructed “standards-based” PACS. One might ask why anyone would go to the time and cost of performing such a task unless there is strong data supporting significantly improved functionality, performance and sufficient and coordinated support, all at an equal or lower cost structure. Deconstruction is so new to the industry and so few organizations have implemented a fully deconstructed environment that it would be reckless to say with any validity that deconstruction proves to boast anything better and cheaper.
So much has been written about deconstructing the PACS environment to provide flexibility. Somehow by tying deconstruction to phrases like “best of breed” or “plug and play”, the unknowing consumer reads “simplicity”. The idea of the “plug and play” flexibility is a nice sound bite, but in reality not as easy as it sounds.
New companies have emerged in this space as well as steady growth among existing PACS vendors that have always been focused on IHE/DICOM standards. This market shift has created a pull from the once full sales funnels of the legacy PACS vendors. What we find now is that the once proprietary PACS vendors have begun course corrections by either driving their software towards open standards or by acquiring the newer vendors to augment their legacy systems. In consideration of the constant mergers and acquisitions occurring in the imaging vendor space, we can make an argument that the once deconstructed is more and more becoming the reconstructed. As this trend continues, the industry is left with the following choices each of which must be understood in the context of an organization imaging goals:
- Fully constructed Legacy (proprietary) PACS (single vendor solution)
- Fully constructed (standards based) PACS (single vendor solution)
- Partially deconstructed PACS (PACS database with a VNA)
- Fully deconstructed PACS (multiple vendor integrated software stack)
Considerations for a Multi-Vendor Approach
One of the trending marketing sound bites being used in the new paradigm of deconstructed PACS is “Plug and Play.” This term denotes the ease of layering together and integrating a software stack where the effort can be seemingly done from a one page instruction manual. This is in fact not the case. With that in mind, each organization must determine their individual path based on understanding the pros and cons of a deconstructed PACS environment and taking into consideration their individually defined goals and capabilities.
Here are just a few of the common issues that must be addressed as part of a partial or full deconstruction of PACS:
- Poor organizational governance pertaining to an enterprise imaging strategy that will not only address radiology in a deconstructed manner, but can ultimately provide the ecosystem for other image producing service lines.
- Underestimating the complexity of fully deconstructed PACS implementation.
- Synchronization of the image data as it relates to Image Object Change Management
