Modernizing an X-ray System: Retrofitting or a New System? - A Guide for Medical Practices, Medical Care Centers, and Hospitals

1. Why Modernizing Digital X-Ray Systems Is Important

Not every older digital X-ray system needs to be completely replaced right away. At the same time, “digital” no longer automatically means “technologically up-to-date.” A digital X-ray system can function reliably from a technical standpoint and still have disadvantages compared to modern systems—for example, in terms of:

This raises the most important question: Does the system still optimally meet today’s clinical, technical, and economic requirements?

2. When is an existing digital X-ray system “too old”?

This question should be answered by considering several different factors:

1. Technical condition: How reliably do the generator, X-ray tube, mechanical components, and detector operate? What is the condition of the wear parts?

2. Image quality: Does the system meet the requirements of current examinations? Do the images allow for reliable diagnosis?

3. Workflow: How user-friendly is the system? How much time does an examination take? How many steps are required to take an image?

4. IT & Integration: How well does the system communicate with RIS, PACS, and other interfaces? Does the current IT infrastructure meet the requirements for minimizing the risk of system failures, data loss, and ensuring security?

5. Service & Lifecycle: Are services such as maintenance, the availability of replacement parts, and manufacturer support guaranteed to continue in the coming years?

3. The Detector as a Key Component of Modernization

In an existing digital system, the detector can be a key starting point for modernization.

Factors to consider include:

Depending on the system, examination protocol, and application, a modern detector can open up opportunities for optimizing image quality, dose, and workflow.

4. Dose optimization is more than just a new detector

It is not true that “the newer the detector, the lower the dose.” Actual radiation exposure depends on the interaction of the entire system and the examination process.

Factors that are relevant include:

Dose optimization is an ongoing process. The goal is not the lowest possible dose at any cost, but rather a radiation exposure appropriate for the specific diagnostic task while maintaining sufficient diagnostic image quality.

5. Software and Digital Workflow: The Underestimated Factor in Modernization

An X-ray system is no longer just an isolated piece of equipment. It is part of an overarching workflow into which it must be fully integrated to achieve the best results.

If the workflow is unnecessarily slow or prone to errors at any point, it can delay the entire process. Therefore, when considering a retrofit solution, the following questions should also be answered:

6. Hardware and Mechanics: The Factors Overlooked in a Pure Software/Detector Comparison

An existing digital system may still perform well in terms of image quality, but mechanically it may no longer be optimally suited to today’s range of examinations.

Relevant factors include, for example:

In such cases, a new detector alone may not provide the desired modernization.

The question here is:

Does only the digital imaging need to be modernized—or is the entire system design no longer optimal?

7. Retrofit Solution vs. Completely New System

The right decision therefore depends not only on the age of the system, but also on the condition and interaction of its individual components.

8. The Six Questions a Practice Should Answer Before Investing

1. What is still working well today?

2. Where do the biggest limitations arise in the current workflow?

3. What types of examinations will need to be performed in the future?

4. Which components actually need to be replaced?

5. What advantages does a new X-ray system offer?

6. Which solution offers the best overall value over the next few years?

EXAMION does not view the modernization of an X-ray system solely as the replacement of a single device. Depending on the initial situation, different components and system levels can be considered—from the detector and image acquisition to software and DICOM integration, all the way up to the complete X-ray system.

In addition to complete X-ray systems, EXAMION also offers DR retrofit solutions for human medicine.
