“HYPER AiR is a software-only device.”
Algorithmimage reconstruction technique which incorporates pre-trained neural networks in the iteration reconstruction process; modification of conventional OSEM by incorporating the pre-trained convolutional neural networks
source quote (p.4)
“HYPER AiR is an image reconstruction technique which incorporates pre-trained neural networks in the iteration reconstruction process to control image noise and contrast. HYPER AiR is a modification of conventional OSEM by incorporating the pre-trained convolutional neural networks into the iteration process. Convolutional neural network is able to distinguish the noise component and the image details, and removes the noise component from the image or enhances the image details.”

Recalls attributed to this device

  • Recalling firm matches this device's applicant (Shanghai United Imaging Healthcare Co., Ltd. No. 2258 Chengbei Rd, Jiading Ind. Shanghai China) — same firm and product code, not necessarily this device · initiated 2023-03-01

    Due to a software issue where the process of patient scanning, the scatter correction may occasionally fail with will potentially cause a failure of the PET image reconstruction and generation of PET images.

  • Recalling firm matches this device's applicant (Shanghai United Imaging Healthcare Co., Ltd. No. 2258 Chengbei Rd, Jiading Ind. Shanghai China) — same firm and product code, not necessarily this device · initiated 2022-05-30

    The wireless VSM module of a mobile PET/CT system, operating in an environment with strong Wi-Fi signals, may experience ECG signal and respiratory signal loss due to Wi-Fi interference. ECG and respiratory signal loss during acquisition can result in the failure of ECG and respiratory-gated reconstruction of the PET scan, which may require rescanning of the patient.

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-07-08.

Reimbursement — how devices like this got paid

Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).

Applicable FDA guidance — what the submission is measured against

FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Radiology panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.

Applicability is derived from the device's FDA advisory panel and pathway — cross-cutting guidances apply to every AI/ML device; panel-specific ones are flagged. Titles, dates, and links verified against fda.gov as of July 2026.
