The summary describes standard PET image reconstruction techniques and does not mention any AI/ML algorithms for image processing, analysis, or interpretation. The performance study focuses on image quality assessment by a radiologist, not on the performance of an AI/ML algorithm.
No.
The device is a PET scanner used for imaging and diagnosis, as stated in its intended use "This information can assist in diagnosis, therapeutic outcome assessment," not for delivering therapy.
Yes
The intended use states that the information obtained from the device "can assist in diagnosis."
No
The device description clearly details hardware components like detectors (SiPM), scintillators (Lutetium), and a physical scanner designed to image the patient's breast or head, indicating it is a hardware device with associated software.
No, this device is not an IVD (In Vitro Diagnostic).
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 about a person's health. This testing happens outside the body (in vitro).
- Device Function: The SET-5002 PET scanner works by imaging the distribution of a radiopharmaceutical within the patient's body. It detects gamma rays emitted from the patient, not from a specimen taken from the patient.
- Intended Use: The intended use is to obtain images of parts of the patient's body to detect abnormal patterns of radiopharmaceutical distribution, which assists in diagnosis and therapeutic outcome assessment. This is an in vivo (within the living body) imaging process.
Therefore, based on the provided information, the SET-5002 PET scanner is an in vivo imaging device, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The equipment is intended to obtain positron emission tomography (PET) images of parts of the human body that fit in the patient aperture (e.g. head or breast) to detect abnormal pattern of distribution of radioactivity after injection of a positron emitting radiopharmaceutical. This information can assist in diagnosis, therapeutic planning and therapeutic outcome assessment.

Device Description
The SET-5002 PET scanner is designed to image the patient's breast or head which is placed in the aperture provided. The scanner can be easily switched from head to breast mode and back again with the push of a button on the control panel: This is the operating principle: When positrons are emitted from the radioactive drug administered to the patient, they annihilate electrons in body tissue. That process emits two annihilation photons (hereinafter "gamma rays") with an energy of 511 keV in the 180-degree direction. The PET System collects data by simultaneously counting both of these gamma rays using detectors arranged in a circular configuration. After collecting data for the specified scan time, an image is then reconstructed from that data based on the quantitative distribution of the radioactive drug. The following corrections are necessary for obtaining a quantitative distribution image: Normalization, Attenuation Correction, Scatter Correction, Random Correction, Decay Correction, Standard Time Correction, Count Losses Correction, and Cross Calibration. Operation of the system requires trained persons. The system is designed to be operated in a controlled medical environment such as a hospital or clinic. The unit is supplied with a computer which acquires and stores patient images. The scintillator type is Lutetium. The detectors are SiPM (Silicon photomultipliers).

Clinical Performance Test: A clinical reader study using the SET-5002 was conducted at U.S. clinical site. The study included review by board certified radiologist to assess whether overall image quality of the SET-5002 demonstrated acceptable diagnostic results for brain and breast. The board-certified radiologist reviewed 12 brain images and 6 breast images, providing PET imaging findings related to the progression of dementia, tumor detection, and the extent of spread. The results of the reader study support the determination of substantial equivalence with predicate device.
