Intended Use
HYPER AiR is an image processing function intended to be used by radiologists and nuclear medicine physicians to reduce noise and improve contrast of fluorodeoxyglucose (FDG) PET images.
Device Description
HYPER AiR is a software-only device. HYPER AiR is an image reconstruction technique which incorporates pre-trained neural networks in the iteration reconstruction process to control image noise and contrast. It is intended to be implemented on previously cleared PET/CT devices uMI 550 (K193241) and uMI 780 (K172143). HYPER AiR serves as an alternative to the existing image reconstruction algorithm that are available on the predicate devices.
More Information

Yes
The device description explicitly states that HYPER AiR "incorporates pre-trained neural networks" and "Convolutional neural network is able to distinguish the noise component and the image details". Neural networks are a core component of machine learning and artificial intelligence.

No
The device is an image processing function that reduces noise and improves contrast of PET images for diagnostic purposes. It is not intended to treat or prevent a disease or condition.

No

Explanation: The device is an image processing function that reduces noise and improves contrast of existing PET images. It is used to enhance images for radiologists and nuclear medicine physicians, but it does not make a diagnosis itself. The device serves as an alternative to existing image reconstruction algorithms.

Yes

The device description explicitly states "HYPER AiR is a software-only device." It is intended to be implemented on previously cleared PET/CT devices, indicating it is a software add-on or alternative reconstruction algorithm, not a new hardware component.

Based on the provided information, no, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health. They are used outside of the body (in vitro).
  • HYPER AiR's Function: HYPER AiR is a software that processes images generated by a PET/CT scanner. It works with the output of the imaging device, not with biological specimens.
  • Intended Use: The intended use is to improve the quality of PET images for interpretation by radiologists and nuclear medicine physicians. This is a function related to medical imaging, not laboratory testing of biological samples.

Therefore, HYPER AiR falls under the category of medical imaging software, not In Vitro Diagnostics.

No
The provided input explicitly states "Control Plan Authorized (PCCP) and relevant text: Not Found," indicating no mention of PCCP authorization.

Intended Use / Indications for Use

HYPER AiR is an image processing function intended to be used by radiologists and nuclear medicine physicians to reduce noise and improve contrast of fluorodeoxyglucose (FDG) PET images.

Summary of Performance Studies

Engineering bench testing was performed to support substantial equivalence and the product performance claims. The evaluation and analysis used the identical raw datasets obtained on UH's uMI 780 and uMI 550, and then applies both HYPER AiR and OSEM to do image reconstruction. The resultant images were then compared for:

  • Performance on noise reduction
  • Performance on image contrast
  • Performance on contrast to noise ratio

Performance tests have been conducted to show that HYPER AiR can improve image contrast while suppressing background noise.

The clinical image evaluation was performed by comparing HYPER AiR with OSEM. Each image was read by three board-certified nuclear medicine physicians who provided an assessment of image contrast, image noise and image quality. The results of the evaluation indicated that HYPER AiR produces images with better image contrast and lower image noise than OSEM while the image quality was sufficient for clinical diagnosis.

Dear Xin GAO:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.
