CT X-ray tubes: how to choose and buy a Chinese alternative in 2026

CT X-ray tubes: how to choose a Chinese alternative in 2026

The X-ray tube (hereafter XT) is the most expensive and fastest-wearing unit of a computed tomography scanner. The resource of an original Philips, Siemens or GE tube is 800–2000 thousand exposure seconds (Ms·exp), while a new one costs from 3 to 12 million rubles. For clinics working with a limited budget or under sanctions restrictions on supplies, Chinese alternatives have become a real option.

This guide is a practical breakdown of 7 Chinese alternatives for CT scanners from Philips, Siemens, GE, Neusoft, Sinovision, United Imaging and MinFound, supplied by Medicaparts. We make no advertising promises: we cover compatibility, price, resource and limitations — so that you can make an informed purchasing decision.

1. What a Chinese CT tube alternative is

Chinese XT manufacturers (Hangzhou Wandong, Beijing Kunlun, Shenzhen Genoray and others) mastered tube production technology for mid-range CT back in the 2010s. Today the market offers:

We work only with full alternatives — new tubes with a factory warranty and a confirmed resource.

2. Compatibility by CT brand

Below is a table of matches "original CT → our alternative", based on the PNs of original tubes that our customers requested in 2024–2026.

2.1. Philips

2.2. Siemens

2.3. GE

2.4. Neusoft

2.5. Sinovision

2.6. United Imaging

2.7. MinFound

3. What the delivery set includes

The standard supply of a Chinese CT tube alternative from Medicaparts:

1. The tube in factory packaging (polyethylene + foam + wooden crate).
2. A certificate of conformity and the product data sheet (in Chinese and English).
3. Installation and calibration instructions.
4. A warranty card (12 months from the date of supply, covering factory defects).
5. On request — a factory test report stating the actual resource of the specific unit.

5. How to identify the right alternative

Step 1. Find out the CT brand and model

The nameplate on the unit's housing or the "System Information" section on the operator console.

Step 2. Find the original tube PN

Three ways:

1. Service documentation — the "X-ray tube replacement" section contains the PN of the original tube.
2. The nameplate on the tube itself — after removing the cover, on the metal plate on the side of the envelope.
3. Replacement history — if the tube was replaced earlier, the engineer's log should state the PN of the previous installation.

Step 3. Match it against the table above

If the PN does not match directly — send us a photo of the nameplate and the engineer will select a compatible alternative.

6. Common selection mistakes

Focusing on price alone. The cheapest tube found on the market is not necessarily the best. A price that is too low often means refurbished units sold as new, or a reduced resource.

Ignoring the CT model. The same external appearance of a tube may correspond to different CTs of different generations. Always verify the PN, not the visual similarity.

No test report. A supplier that respects itself provides a factory test report. Its absence is a reason to think twice.

Installation without calibration. After replacing the tube, air and phantom calibration is mandatory. Without it — image quality degrades and the load on the tube increases.

Ordering without consulting an engineer. Send us the PN or a photo before payment — we will confirm compatibility. This is free of charge.

7. Lead times

The exact lead time depends on the chosen model and the current workload of the manufacturing plant. When requesting, state the CT model and the required date — we will offer the optimal option.

8. How to order

1. Request — write to Telegram @GEpartsV_bot or email [email protected]. State the CT model, the original tube PN (if you know it) and the desired delivery date.
2. Confirmation — our engineer will check compatibility and send a commercial offer with price, lead times and payment terms.
3. Contract — signing of the supply contract (for legal entities) or invoice (for individuals via sole proprietorship).
4. Prepayment — 30–50% depending on stock availability. The balance — before shipment.
5. Delivery — shipment from the factory, tracking, delivery to your address.
6. Installation — on your own (if you have an engineer) or with the involvement of our partner engineer in your region.
