No
The summary describes standard image reconstruction and processing techniques for PET/CT systems and does not mention any AI or ML components.
No.
The device is described as a diagnostic imaging system used to gather information for evaluation, detection, diagnosis, and therapeutic planning/outcome assessment, not for direct therapeutic intervention.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the information gathered by the device "can assist in the evaluation, detection, diagnosis, therapeutic planning and therapeutic outcome assessment of (but not limited to) cancer, cardiovascular disease and brain dysfunction." This direct mention of "diagnosis" clearly indicates its diagnostic purpose.
No
The device description clearly states it is a large bore, TOF, PET-CT system, which combines hardware components (CT and PET systems) with software for image reconstruction and fusion. It is not solely software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used outside of the body.
- Device Function: The description clearly states that this device is a diagnostic imaging system that uses PET and CT to image the distribution of radiopharmaceuticals within the patient's body. It gathers information from the patient directly, not from a sample taken from the patient.
- Imaging Modality: The input modalities are PET and CT, which are in-vivo imaging techniques.
Therefore, based on the provided information, this device is an in-vivo diagnostic imaging system, not an in-vitro diagnostic device.
N/A
Intended Use / Indications for Use
The device is a diagnostic imaging system that combines Positron Emission Tomography (PET) and X-ray Computed Tomography (CT) systems. The CT component produces crosssectional images of the body by computer reconstruction of x-ray transmission data. The PET component images the distribution of PET radiopharmaceuticals in the patient body. The PET component utilizes CT images for attenuation correction and anatomical reference in the fused PET and CT images.
This device is to be used by a trained health care professional to gather metabolic and functional information from the distribution of the radiopharmaceutical in the body for the assessment of metabolic and physiologic functions. This information can assist in the evaluation, detection, diagnosis, therapeutic planning and therapeutic outcome assessment of (but not limited to) cancer, cardiovascular disease and brain dysfunction. Additionally, this device can be operated independently as a whole body multi-slice CT scanner.

Device Description
Celesteion, PCA-9000A/3, V6.4, is a large bore, TOF, PET-CT system, which combines a high-end CT system with a high-throughput PET system. The high-end CT system is a multi-slice helical CT scanner with a gantry aperture of 900 mm and a maximum scanning field of 700 mm. The highthroughput PET system has a time of flight (TOF) detector with temporal resolution of 450 ps. Celesteion, PCA-9000A/3, V6.4, is intended to acquire PET images of any desired region of the whole body and CT images of the same region (to be used for attenuation correction or image fusion), to detect the location of positron emitting radiopharmaceuticals in the body with the obtained images. This device is used to gather the metabolic and functional information from the distribution of radiopharmaceuticals in the body for the assessment of metabolic and physiologic functions. This information can assist research, diagnosis, therapeutic planning, and therapeutic outcome assessment. This device can also function independently as a whole body multi-slice CT scanner.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Risk analysis and verification/validation testing conducted through bench testing are included in this submission which demonstrates that the established specifications for the device have been met.
The modified system utilizes the "985ViSION CT Detector that was previously 510(k) cleared under K150003. Image quality metrics studies concluded that the subject device is substantially equivalent to the predicate device with regard to spatial resolution, CT number and contrast-to-noise ratio and noise properties. Additional bench testing was conducted to support PSF claims including improved contrast recovery, sharper point source in air, more uniform point size across the field of view, ringing artifact reduction, SUV increase and reduced reconstruction time.
Testing of the subject device was conducted in accordance with the applicable standards published by the International Electrotechnical Commission (IEC) and the National Electrical Manufacturers Association (NEMA) for Medical Devices, CT and PET Systems.

15. SUBSTANTIAL EQUIVALENCE:
Celesteion, PCA-9000A/3, V6.4, is substantially equivalent to Celesteion, PCA-9000A/2, which received premarket clearance under K140651 and is marketed by Toshiba America Medical Systems. The Celesteion, PCA-9000A/3, V6.4, incorporates modifications to the cleared device including implementation of the PUREVision CT detector previously cleared under K150003, implementation of SEMAR, a previously cleared metal artifact reduction software application, a PET respiratory gating system, improvements to PET image visualization using Point Spread Function (PSF) correction and introduction of SUBEFIIght, new marketing terminology for existing device features, in device labeling. These changes do not affect the safety or efficacy of the cleared device, as demonstrated in performance testing. The method of operation and manufacturing process for the Celesteion remain unchanged from the cleared device.
