No
The document mentions "advance algorithms based on OSEM" to improve image quality, but does not explicitly state or imply the use of AI or ML. The focus is on image reconstruction and processing methods.
No
The device is described as an "imaging system" used for "functional and anatomical imaging" to provide "diagnostic information," and to "assist in radiotherapy planning." It does not provide treatment or therapy directly.
Yes
The "Intended Use / Indications for Use" section states that the device "can assist in radiotherapy planning and be used as a stand-alone head and whole body multislice computed tomography (CT) diagnostic imaging system." It also mentions that "Trained doctors can read useful diagnostic information from the image generated."
No
The device description explicitly states it is an "integrated multi-slice Computed Tomography and Positron Emission Tomography scanner" and details hardware components like the CT part being the same as NeuViz64. This indicates it is a hardware device with integrated software, not a software-only device.
Based on the provided information, the NeuSight PET/CT Scanner System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- NeuSight Function: The NeuSight PET/CT Scanner System is an imaging device. It directly scans the human body using PET and CT technology to generate images for diagnostic purposes. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states "functional and anatomical imaging of human bodies and organs" and "assist in radiotherapy planning." This aligns with the function of an imaging system, not an IVD.
Therefore, the NeuSight PET/CT Scanner System falls under the category of medical imaging devices, not In Vitro Diagnostic devices.

Device Description
The NeuSight PET/CT Scanner System is an integrated multi-slice Computed Tomography and Positron Emission Tomography scanner. It uses CT images to correct for non-uniform attenuation of the PET images and it uses integrated CT and PET images to localize emission activity in the patient anatomy. NeuSight System has capabilities for imaging all available PET tracers and CT contrast agents and can provide inherently registered anatomical and functional information via an integrated graphical user interface. The product provide some reconstruct methods, such as FBP, 3DRP, OSEM, ClearView (cleared in K133373), and some advance algorithms based on OSEM. These advance algorithms can improve the image quality.
The NeuSight PET/CT Scanner System consists of two variants:
- NeuSight PET/CT 64
- NeuSight PET/CT 16
NeuSight PET/CT 16 is designed based on NeuSight PET/CT 64 and has the same hardware configuration with NeuSight PET/CT 64. Their hardware of CT part is the same as NeuViz64 (K121792). In the performance parameters, NeuSight PET/CT 16 only limits the optional scope of partial scan parameters by software in order to different from NeuSight PET/CT 64. There's no essential technological difference between the two types of PET/CT and the safety and effectiveness of these products could be ensured through verification, validation and difference assessment.
