Which CT scan machine is the best in India?


When looking for the best CT scan machine, there are a number of features and specifications to look out for. It is important to take into consideration factors such as speed, resolution, image quality, types of imaging available (3D or 4D), patient safety, and comfort level measures offered by the scanner.

Different machines may come with various safety and comfort features such as adjustable beds and auto shut-off for patient convenience. There are energy efficiency considerations when looking for a CT scanner since devices can consume large amounts of electricity during use. 

Points to consider when looking for a CT scan machine

  • Firstly, pay attention to the ergonomics design and general operation capabilities so that you can be assured that your workplace has an optimal setup for its users.
  • Many machines also come equipped with noise reduction technology allowing operators to focus on other tasks during long acquisition times.
  • Price is an important factor in choosing a device – higher quality products tend to cost more but they offer better performance too.
  • Check with suppliers who have experience using different machines so they can provide valuable insight.
  • It’s also helpful to get feedback from other clinicians who have experience as it will be helpful in making your final decision.

Additionally, you should research different brands in order to get a better idea of which one will provide the highest quality visuals. All of these features should be weighed when making a decision on which machine will be best suited for your needs.

Which CT Scan machine is best suited for your hospital?

CT scans are an essential and highly beneficial diagnostic tool used in modern medicine. But with all of the different types of machines available, how do you choose which one best suits your hospital’s needs?

In this article, we will explore what to consider when selecting a CT scan machine that will provide superior patient comfort as well as optimal image quality results. 

Speed

Most high-end scanners have features like automated gantry positioning and accelerated table motion. It helps to ensure quicker exam times without compromising the accuracy or safety of the patient.  

Image Quality

The number one priority when selecting a scanner should be achieving excellent image resolution. 

1) Motion Correction – The ability to correct motion artifacts during scanning saves time by allowing fast scanning without compromising image quality; 

2) Multi-Slice Imaging Capacity – Number and type (helical/zoom etc.) slices per rotation determine efficiency and flexibility, minimizing dose while maximizing data acquisition rates; 

3) Automated Tuning – Most leading vendors sell automated tuning capability but its implementation varies between systems ; 

4 ) Uniformity Enhancement Technology (UET)– UET compensates for shading caused due differences in X-ray beam energy backscatter from anatomy heterogeneities. These are interposed along path length on the patient travel platform creating improved uniformity across field coverage regions (at least 6×6 inches). 

Cost

You may need to factor in both the initial cost of purchase as well as any ongoing maintenance or repair costs associated with different machines. 

Accessibility & Ergonomics

It’s important not only that access points and pathways around the room permit easy movement but also that special attention must be paid to ergonomic design principles.

Radiation Dose Reduction Technology

Modern scanners typically come equipped with low-dose software packages such as Adaptive Statistical Iterative Reconstruction (ASIR) algorithms. It is designed specifically to reduce radiation doses while not detracting from the clarity of images produced.

Make sure any unit selected has such necessary dosage reduction code capabilities installed already to save costs by negating the need for external updates later. 

Cost/Long-term Savings Potential

Comparison shop based upon expected long-term maintenance expenses over life expectancy rather than just initial cost outlay.  Since medical Imaging equipment can last up to 10 years + if properly serviced before replacement.

Investing in higher-end models offering extensive technical support makes sense economic sense given lower service costs down the road overall.

Evaluate your Workflow

The Patients flow, gathering your patient’s record, and monitoring per-day record will give you a clear view of your workflow, and the scanning type. From a 16-cut scanner to a modern 64-cut machine, your decision relies upon what you want it to do. It’s fundamental that you purchase a CT scanner that will streamline your work process. 

Slice Counts

Slice counts are one of the most important features when purchasing a CT scan machine. More the slice counts, the higher the image resolution and it reduces scan time. 

  • 4 Slice: Often considered to be ideal for a low-volume imaging center, as well as urology practices or other centers that only need the CT scanner once or twice a week.
  • 16 Slice: Best for facilities with a higher patient flow and a need for reduced scanning times. This slice count also works well in urgent care centers, as well as hospitals or high-volume imaging centers. 
  • 64 Slice:  Ideal for cardiac, trauma, or high-volume critical care environments where time is of the essence.
  • 128 Slice:  Commonly found in cardiac or research institutions. Scanners with this power, as well as 256- or 320-slice scanners, can scan the whole body in seconds and provide incredibly sharp 3D images of any organ.
  • 320, 640 Slice: These CT scanners are advanced imaging systems that can scan the whole body from head to toe, in less than one minute. Therefore, these systems are great for emergency rooms.

Look for a few scanners that fit your budget and needs and simultaneously compare the models with respect to their speed, image resolution, slices, etc. 

Other Technical Considerations: 

  • Air Cooled feature
  • Gantry rotation
  • X-Ray tube performance and Lifespan
  • Sustainability and maintenance needs
  • Spatial and Contrast Resolution
