Everything You Need To Know About CT X-Ray Tubes

When it comes to a CT (Computed Tomography) scanner, the X-ray tube isn’t just a part – it’s the heart. The X-ray tube is what generates beams needed to create those detailed cross-sectional images of the body during CT scans, crucial to diagnosing medical conditions.

So, how does a CT X-ray tube work, exactly?

Well, the CT scanner uses a special tube to emit X-rays, which pass through the patient’s body and are captured by detectors in the scanner. During a CT scan, the patient lies on a moving bed, and the X-ray tube rotates around them, sending thin beams through the body. Digital detectors are placed opposite the X-ray source, so when the X-rays exit the patient, they’re picked up and sent to a computer. The computer then creates image slices of the patient, with each slice representing a specific thickness of tissue, usually around 1-10mm.

These image slices can be viewed individually by doctors or stacked together by the computer to create a 3D image of the patient’s body, showing bones, organs, tissues, and any medical issues. The 3D view helps in precise diagnosis. So, now you get why X-ray tubes are crucial to the functioning of a CT scanner.

Are X-ray tubes expensive?

Yes. X-ray tubes are the costliest component within a CT system. So, if you are planning to get a CT scanner for your hospital or practice, understand the expected lifespan of the tube and the expenses associated with replacements.

How long does the X-ray tube last?

Several factors can impact the lifespan of a CT X-ray tube. For example, the number of scans performed the tube’s heat capacity, and the quality of cooling systems in place. Also, remember, that proper maintenance plays a crucial role in extending tube life.

How do I know if a CT X-ray tube needs replacement?

Does your CT scanner make unusual noises during scanning? Do frequent error messages keep showing up? Is the scanner overheating issues or has the image quality decreased? These are all signs that the tube is failing and you will need to consult a qualified technician sooner than later. But remember, when buying a replacement CT X-ray tube, evaluate warranty coverage and the reputation of the supplier.

New or refurbished – what should I go for?

Refurbished CT scanners and X-ray tubes are just as good as new ones and are more cost-effective too as long as they are procured from vendors who meet quality and safety standards and come with a warranty. The experts at Blue Star E&E can help you make a well-informed choice.
