What SubtlePET changes for your department

Improved workflow

SubtlePET improves the quality of accelerated scan protocols enabling an optimized workflow.

Maximize Scanner Utilization

SubtlePET is a virtual upgrade to your existing fleet so you don’t need to purchase new and expensive PET scanners, extending the life of your existing machines.

Fewer potential rescans

SubtlePET improves the image quality of sub-optimal scans.

Ease of use

SubtlePET is designed to integrate into your existing PET imaging workflow, sitting between the scanner and PACS to support efficient image processing without requiring major changes to your current workflow.

“”Our goal at Precision Imaging Centers is to deliver the best patient care possible. We pride ourselves on being early adopters of innovative technology, which differentiates us from other imaging centers. Using SubtlePET, we are able to maintain superior image quality of our accelerated protocols. It also allows us to complete more CT’s on the same scanner. The ability to conduct these faster scans both increases our workflow efficiency and creates a better patient experience by getting patients in and out of the scanner faster. It’s a win-win for us and for them.””
  • Solution

SubtleHD™(PET), by Subtle Medical

The AI software that powers the Cardiology AI solution on this page.
SubtleHD™(PET) is an AI image‑enhancement engine developed by Subtle Medical, a Stanford‑founded medical AI company. It uses deep learning to reconstruct high‑quality PET images from lower‑count acquisitions, so a department can shorten scan times or reduce radiotracer dose while keeping image quality consistent with a full‑count scan.

The software sits between the scanner and PACS, so it slots into existing oncology and general PET/CT workflows without requiring any new hardware or a change to how staff already work.

SubtlePET FAQ

SubtleHD™(PET) is an AI image‑enhancement engine from Subtle Medical. It uses deep learning to reconstruct high‑quality PET images from lower‑count acquisitions, improving image quality on accelerated scans.
No. SubtleHD™(PET) is a software upgrade that sits between the scanner and PACS, extending the useful life of your existing PET/CT fleet without new hardware purchases.
Depending on the protocol, departments have reported scans running up to roughly 75% faster, as shown in the before/after acquisition‑time comparison on this page — while maintaining diagnostic image quality.
Yes. Because the AI enhances lower‑count acquisitions, departments can choose to trade the accelerated protocol for a reduced tracer dose instead, depending on clinical priorities.
SubtleHD™(PET) is designed to integrate into existing oncology and general PET/CT imaging workflows across standard scanner fleets, without requiring major workflow changes.
