Siemens’ Healthineers Hardware Evolution

Siemens Healthineers’ Shape 22 pre-RSNA event featured a pair of ambitious hardware announcements that stand to expand what can be done with CT exams and where MRIs can be performed.

NAEOTOM Alpha PCCT – Siemens Healthineers confirmed its pole position in the Photon-Counting CT race, officially launching its NAEOTOM Alpha scanner. Although the NAEOTOM Alpha already received a rare marketing head-start from the FDA, this week’s launch begins its official 2022 rollout, and provides new details about this milestone product:

  • Far higher image quality than CT
  • Provides much more imaging data and new levels of CT-based insights
  • Expands CT to new cardiac, oncology, and pulmonology use cases
  • Allows 50% lower radiation dosage, could shift exams to non-contrast
  • Supports Siemens’ core solutions, including operability and AI-based diagnosis
  • Cleared in US and Europe, 20 systems already installed, 8k patients scanned
  • PCCT expected to become the main CT technology within 10 years
  • Siemens is holding another NAEOTOM Alpha event today (Nov. 18)
  • Siemens might be first, but we’re seeing more PCCT activity from GE Healthcare, and Canon and Philips aren’t far behind

MAGNETOM Free.Star MRI – One year after introducing the MRI-expanding MAGNETOM Free.Max, Siemens continued its MRI accessibility push, revealing the “disruptively simple” MAGNETOM Free.Star. The new Free.Star MRI will inherit much of the MAGNETOM Free.Max’s accessibility-friendly qualities (0.55T, small/light, low helium & installation requirements), and will have the ambitious goal of supporting the half of the world’s population that doesn’t have MRI access. The MAGNETOM Free.Star is still early-stage (it hasn’t begun the FDA process), but it’s massive healthcare ambitions make it worth keeping an eye on.

The Takeaway – The NAEOTOM Alpha is expected to be the start of a major shift towards Photon-Counting CT, while the new MAGNETOM Free.Max and Free.Star could expand where MRIs are used. That makes these extremely significant products.

Siemens’ First Photon-Counting CT

The FDA announced the 510(k) clearance of Siemens Healthineers’ NAEOTOM Alpha photon-counting CT scanner, calling it “the first new major technological improvement for Computed Tomography (CT) imaging in nearly a decade.” Those are some big words from a federal agency not known for hyperbole, and it doesn’t appear they are exaggerating.

About Photon-Counting CTs – Photon-counting CTs (PCCTs) produce far higher quality images than traditional CTs, with lower radiation and contrast dosage. Unlike standard CTs that simultaneously measure the total energy from many X-rays (at the expense of image info, clarity, and contrast), photon-counting CT detectors directly convert each individual X-ray photon into digital electrical signals that are then “counted.”

The NAEOTOM Alpha – The NAEOTOM Alpha might be the first PCCT scanner, but the star of this announcement is its detector. The new photon-counting detector leverages a CdTe active detection layer to achieve PCCT’s targeted image/dosage/contrast advantages, and it could be the foundation of Siemens’ PCCT portfolio for years to come. 

The PCCT Race – The other major OEMs seem to be doing everything they can to earn a spot among the PCCT leaders. GE Healthcare and Canon both acquired PCCT detector makers within the last year and are planning their own PCCT launches, while Philips appears to have ramped up its PCCT R&D.

The Takeaway – PCCT has been viewed as the “future” of CT technology for quite a while, and that future just became a lot closer with last week’s announcement. We’re going to see similar PCCT launches from the other major OEMs, but Siemens Healthineers will enjoy its role as the only player with an FDA-approved PCCT scanner until then.
