A Chinese company has created a non‑rotating CT scanner that offers four times higher resolution and cuts radiation exposure by over 50%. The fixed system provides a 3072×3072 image quality, and clinical trials began in 2025.
中国一家企业研制出无旋转式CT扫描仪，分辨率提升至原来的四倍，辐射剂量降低50%以上。
该固定式设备可实现 3072×3072 的图像精度，已于2025年启动临床试验。

realistically, when can this get to the USA?
说实话，这东西什么时候能进入美国？

Realistically, NanoVision's phased array CT (fixed, no rotation) just wrapped early clinical trials in China (started Aug 2025, ~400 scans). They aimed for NMPA Class III approval by end-2025—so likely cleared there now.
说实话，纳米视觉的固定式相控阵CT（无需旋转）刚刚在中国完成早期临床试验，该试验于2025年8月启动，共完成约400次扫描。他们原本计划在2025年底获得中国国家药监局三类医疗器械认证，现在应该已经获批了。
For USA: FDA review for novel high-end imaging gear typically adds 12-24+ months post-local data (pre-sub, submission, possible extra US trials). Earliest realistic availability: 2027-2028 if trials shine and no delays. Geopolitics/supply chain could stretch it. Promising breakthrough though!
至于美国市场，新型高端影像设备在拿到中国临床数据后，通常还需要12到24个月甚至更久才能通过FDA审批，流程包括预审、材料提交，可能还需要在美国补做临床试验。如果试验顺利且没有延误，最早也要到2027至2028年才能在美国上市，地缘政治和供应链问题还可能进一步推迟时间，但这确实是一项很有前景的技术突破。

They just produced a GE scanner knock off and over hyped the specifications is what the title should state.
标题其实应该这么写：他们只是山寨了通用电气的扫描仪，还过度夸大了设备参数。
The Law
Suggesting China copied something again is pathetic and shows very little knowledge into the subject, as well as a severe degree of underestimating what the Chinese are capable of today.
动不动就说中国抄袭实在很没意思，这只能说明你根本不了解这个领域，还严重低估了如今中国人的技术实力。
The Law
Maybe the title should read 'China invents solid state CT scanner while US sleeps on old'.
标题或许应该改成：中国发明了固态CT扫描仪，而美国还在守着老旧技术不思进取。

Not suggesting, I’m saying it. China has a history of state sponsored industrial espionage. They do not respect IP rights. I have seen this first hand.
我不是暗示，我就是明确表态。中国长期存在商业窃密行为，不尊重知识产权，这些我都是亲眼见过的。
The Law
That's nice but you're missing the point.
No other company has a solid state CT, China does.
你说的这些都无关紧要，根本没抓住重点。目前全球没有任何一家公司能做出固态CT，只有中国做到了。

American products are always expensive and slow to update. Therefore, China should break this monopoly. More patients can get affordable treatment.
美国的产品一向价格昂贵、更新缓慢，所以中国就该打破这种垄断，让更多患者能用得起医疗设备、看得起病。
Yes. As a patient, I only hope that medicine will progress as soon as possible, instead of letting these pharmaceutical companies eat the old technology all the time. They should speed up the examination and approval and explore new methods.
没错，作为一名患者，我只希望医学技术能尽快进步，不要让这些医疗企业一直守着旧技术吃老本，审批流程应该加快，多去探索新的技术方案。

True, Europe has the same problem, mostly due to legislation and bureaucracy.
确实如此，欧洲也面临同样的问题，主要是因为法规限制和官僚流程过于繁琐。

Can you tell us which GE model that is? AI seems baffled by the premise you suggest
你倒是说说看，他们山寨的是通用电气的哪一款产品？就连AI都看不懂你这套说法。

The NanoVision-branded phased-array (non-rotating) CT scanner — sometimes referred to as a “static CT” or phased-array CT — is widely reported as the first of its kind in the world and was developed in China by a Chinese company called NanoVision Technology.
纳米视觉品牌的相控阵不旋转CT扫描仪，也被称作静态CT，被公认为全球首创，由中国的纳米视觉科技公司自主研发。
Newguy3
Assuming they did (which they didn’t cause GE doesn’t make a non rotating scanner) if it is much cheaper than the original then there is nothing wrong
就算退一步假设他们抄袭了（实际上根本没有，因为通用电气根本不生产不旋转的CT），只要这款设备比原版便宜很多，那也没什么问题。

Always whining when other companies make a better products. Afterall, aren’t you for a capitalist society? If you think they copied, why don’t you too copy them and make a much better one?
别人做出更好的产品，你们就只会抱怨。你们不是一向崇尚资 本主义吗？要是真觉得别人抄袭，有本事你们也照着做，然后做出更好的产品啊。

How much more cheaper will this be compared to a regular CT scanner?
这款设备和普通CT扫描仪相比，能便宜多少？
Gro
This phased-array CT from NanoVision is still in clinical trials (no commercial price yet). Regular CT scanners typically cost $100K–$2M+.
纳米视觉的这款相控阵CT目前还处于临床试验阶段，暂时没有商用定价，普通CT扫描仪的售价通常在10万到200多万美元之间。
Its fixed dual-ring design skips the complex rotating gantry, plus 100% domestic Chinese components (tubes, detectors, etc.), so expect it to be substantially cheaper—likely 40-60% less once scaled and certified. More details soon!
它采用固定双环设计，省去了复杂的旋转机架，而且球管、探测器等所有零部件均为中国制造，因此价格会大幅降低，量产并通过认证后，预计能比普通CT便宜40%到60%，很快会公布更多详细信息。

Stationary-source CT has been a hardware nightmare since the 90s — distributed X-ray sources solve rotation but tank signal/noise ratio. How'd they crack the photon collection geometry without a gantry spin?
从上世纪90年代开始，固定源CT就一直是硬件领域的难题，分布式X射线源虽然解决了旋转问题，但会导致信噪比大幅下降，他们在不使用旋转机架的情况下，是如何攻克光子采集结构难题的？

Stationary source + detector ring means you're eating massive scatter unless they built some kind of coded aperture system. The real flex would be if they're doing computational ghost imaging at clinical speeds.
固定射线源加探测环的设计会产生大量散射辐射，除非他们采用了编码孔径技术，真正厉害的是他们能否以临床适用的速度实现计算鬼成像。

We now have the technology to see the human body in 4k resolution but the hospital will still make you fill out three different paper forms with a pen that barely works.
我们现在已经拥有4K分辨率观测人体的技术了，可医院还是会让你填写三张不同的纸质表格，就连给的笔都几乎写不出字。

This will really makes scanners safe, hope the trials will conclude successfully

sorry, they meant 4x more radiation
also the paint is lead
抱歉，他们说的其实是辐射量高出四倍，而且设备油漆还含铅。

China has some of the best engineers in the world. You have every right to be proud of your achievements.

Promising innovation. If clinical results confirm these improvements, it could significantly enhance diagnostic precision while making scans safer for patients
这是一项极具前景的创新，如果临床结果能证实这些优势，将大幅提升诊断精度，同时让扫描检查对患者更加安全。

It's not like it hasn't been tried before. Kudos to China if it has improved the technology.
这种技术之前也有人尝试过，如果中国真的成功改进并实现突破，那确实值得称赞。
Stevarino1020
I saw a few papers on non rotating CT scanners. Instead of rotation ,they use multiple xray sources that can switch very quickly in a phased array. I presume because of fast switching and more efficient detectors they can reduce total radiation.
我看过几篇关于不旋转CT的研究论文，这种设备不靠机械旋转，而是采用多个X射线源在相控阵中快速切换，我认为正是快速切换和高效探测器的结合，才实现了总辐射量的降低。

can it fit on top or inside the sides of an ambulance, so it can scan while moving a patient to the hospital, maybe even send the data ahead.
这台设备能装在救护车上或者车身侧面吗？这样在送患者前往医院的途中就能完成扫描，甚至可以提前把检查数据传输到医院。

A non-rotating CT scanner is a paradigm shift in diagnostic imaging. Reducing radiation while quadrupling resolution is a massive win for patient safety and clinical precision. The engineering required for a fixed-source system of this scale is truly impressive
不旋转CT扫描仪是诊断影像领域的颠覆性变革，在降低辐射的同时将分辨率提升四倍，对患者安全和临床诊断精度而言都是巨大突破，打造这种规模的固定源系统所需要的工程技术实力实在令人惊叹。

These are the fruits of china huge pivot to high tech sector. Imagine if china is leading in most high tech equipment, it will automatically be able to double its current gdp. Europe and usa will be develo countries once more
这是中国大力转向高科技领域发展的成果，试想一下，如果中国在多数高端科技设备领域占据领先地位，其GDP完全有可能实现翻倍，到时候欧美国家或许会再次变成发展中地区。
