Hospital machines, including CT scanners, MRIs, x-ray machines, ultrasound machines, etc., require an upgrade or replacement at some point. According to a survey, CT (computed tomography) scanners have transformed how doctors study the human body and establish a prognosis. The global CT scanner market is also growing significantly and is expected to reach $6.2billion by the end of 2022.

Having a quality CT scanner is essential to offer patients the best services. Whether you want to replace your existing CT scanner with the latest technology in the market or want a quality refurbished one, it is beneficial to know your options. Here is what to consider.

Understand your clinical requirements

First, you must realize and understand your goal for purchasing a CT scanner. Buying or replacing a CT scanner means you have already identified a need in your lab or medical facility. Some questions to evaluate include:

• what kind of exams will you perform with the CT scanner?
• Do you need it for medical studies? If so, what studies?
• Will you use the CT scanner for a new range of cardiac, pediatric, or bariatric services?

Understanding your clinical requirements will help you select the ideal system for your needs.

Technical specifications

The technical specifications of a CT scanner will greatly influence your purchase decision. Key specifications include:

Slice count

The slice count in a ct scanner determines how many cross-sectional images the machine can produce with each rotation. For instance, a 16 slice CT would be ideal for general studies and facilities with a low volume of patients. However, a 32 or 64slice CT would be the best option if you want to stay up to date with industry standards.

Detector area coverage

Another essential feature to check is the detector area coverage, which measures how much body the machine can scan. The detector area coverage can differ even in CT machines with the exact slice count.

Ideally, the greater the detector area coverage, the lesser the amount of stitching required to review images of an organ. For instance, the detector area coverage for a 64slice ct scanner used in critical situations like cardiac and trauma can range from 19.5-40mm.

Other features

A quality high-end ge CT scanner will have more advanced features like modern detectors and software options designed for specialized applications. Premium CT scanners have slice counts of 128-320 and even higher. Your goals and clinical needs determine the technical specifications that work for you.

Tube type and usage

A CT scanner has an x-ray tube that serves as its energy source. It comes with a limited lifespan and is replaceable after a certain period of use. You can recondition or refurbish the tube to extend its lifespan, but it is advisable to inquire about its usage and value before purchasing the machine.

Used, refurbished, or new

A used CT scanner can be pricier than a refurbished one, but the condition may be better. A refurbished CT scanner has a lower cost upfront than a new one. Ideally, a new CT scanner is always the best option, but your choice depends on your budget.

The takeaway

Research extensively about the machine’s specifications before purchase and consider repair and maintenance options.
