Welcome, fellow creatures of the radiology night. A vendor has announced a new photon-counting CT (PCCT) system with the widest detector coverage yet claimed, and my counting compulsion insists we look closely before we cheer.
Key takeaways:
- Neusoft Medical introduces the NeuViz P10, a PCCT system with 8 cm of axial coverage, unveiled at RSNA 2025 [1].
- Every spec attached to the P10, including the 8 cm figure, 50 lp/cm resolution, and dose-reduction claims, comes from Neusoft’s own materials; none has independent or peer-reviewed confirmation [1].
- AuntMinnie’s independent RSNA coverage called the exhibited unit a “works-in-progress,” a qualifier Neusoft’s own press release does not use [4].
- Coverage width is becoming a real competitive line in PCCT: Siemens’ NAEOTOM Alpha class ships at 6 cm single-source [7,8,9], and GE’s Photonova Spectra earned FDA clearance in March 2026 with commercialization plans for a 4 and 8cm version. [10,11].
What Neusoft announced at RSNA 2025
Neusoft Medical Systems unveiled the NeuViz P10 in December 2025 at the RSNA annual meeting in Chicago. [1]. The system uses a cadmium zinc telluride (CZT) semiconductor detector, a material choice distinct from the cadmium telluride detectors used in some competing designs. Neusoft’s materials also state a spatial resolution of 50 lp/cm, “substantially reduced radiation dose,” and multi-energy imaging for tissue characterization [1]. None of these figures arrives with published methodology, phantom conditions, or a comparator scanner, so their real-world meaning cannot yet be assessed.
A separate Neusoft release, dated August 27, 2025, adds a wrinkle. It states that a NeuViz P10 configuration had already received market approval from China’s National Medical Products Administration (NMPA) months before the RSNA unveiling, calling it “the world’s first wide-body system equipped with an 8-cm detector” [6]. Whether the RSNA-exhibited unit and the NMPA-approved configuration are the same product is not something the available sources resolve.
What is verified, and what is not
Every technical claim about the NeuViz P10 traces back to Neusoft’s own press materials, reproduced nearly verbatim by trade outlets including PR Newswire, BioSpace, and Asian Hospital & Healthcare Management [1,3,5]. No peer-reviewed publication, phantom study, or independent bench test of the P10’s coverage, resolution, or dose performance has surfaced in the sources reviewed for this piece.
The one piece of independent framing available cuts the other way from the marketing. AuntMinnie’s trade coverage of the RSNA booth describes the exhibited system as a “works-in-progress” [4], a phrase absent from Neusoft’s own announcement. Set against Neusoft’s earlier claim of NMPA approval for an 8 cm P10 configuration, the two statements sit awkwardly together.
No FDA clearance, CE marking, or other regulatory status outside China was identified for the P10 in the sources reviewed here.
Where the P10 sits next to Siemens and GE
Detector coverage is shaping up as a genuine point of competition among vendors pursuing photon-counting CT, each with a different detector material.
- Siemens Healthineers’ NAEOTOM Alpha class ships with 6 cm of coverage on its single-source Alpha.Prime and Alpha.Peak models, or 2×4 cm in the dual-source Alpha.Pro configuration, with a dual-source volumetric scan speed up to 74 cm per second, according to Siemens’ own product materials [7,8,9].
- GE HealthCare’s Photonova Spectra, built on a silicon detector, received FDA 510(k) clearance in March 2026 after debuting at RSNA 2025. The system will be offered with either an 80 mm dSi detector and 40 mm dSi detector model configurations, commercialized as Photonova Spectra and Photonova Spectra Select, respectively. [10,11].
- Neusoft’s NeuViz P10 claims 8 cm of coverage with a CZT detector, which would be wider than Siemens’ current single-source offering. [1].
FAQ
What does “8 cm coverage” mean for a CT scanner?
It refers to the width of anatomy, measured along the direction the patient table moves, that the detector can image in one rotation without repositioning the table. Wider coverage can, in principle, reduce the need to stitch together multiple acquisitions for whole-organ or cardiac imaging.
Is the NeuViz P10 available in the United States?
No evidence of FDA clearance for the P10 was found in the sources reviewed for this article. A separate Neusoft release states a P10 configuration received NMPA approval in China, which is a different regulatory pathway.
How does the P10 compare to Siemens’ NAEOTOM Alpha or GE’s Photonova Spectra?
Siemens’ current single-source NAEOTOM Alpha models offer 6 cm of coverage; GE’s Photonova Spectra will be commercially available in 8 and 4cm configurations.
What is a CZT detector?
Cadmium zinc telluride is a semiconductor material that converts X-ray photons directly into electrical signals, one of several materials used across different photon-counting CT detector designs.

Four centuries of counting has taught me patience with numbers I cannot yet verify. The NeuViz P10 may well earn its place on the competitive map of photon-counting CT. For now, it is a specification sheet from a trade-show floor, and I shall count it as exactly that until someone outside Neusoft’s marketing department measures it themselves.
Until then, dear colleagues: watch the regulatory filings, not the press releases.
