• Device Name: GEMINI 16
• Applicant: Philips Medical Systems (Cleveland), Inc.
• Product Code: KPS · Radiology
• Decision Date: Jul 11, 2003
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 892.1200
• Device Class: Class 2
• Attributes: 3rd-Party Reviewed

Intended Use

The device is an imaging system that combines Positron Emission Tomography (PET) and X-ray Computed Tomography (CT). The device produces attenuation and nonattenuation corrected images of the distribution of PET radiopharmaceuticals in the head, body and total body as well as x-ray transmission images of these areas. The PET and CT images are registered and displayed in a "fused" (overlaid in the same spatial orientation) format to provide combined PET and anatomical data at different angles for interpretation by trained health professionals. The PET and CT portions of the system can be used either as an integrated system or as a stand-alone PET or CT system. The device can provide CT data suitable for use in attenuation correction.

Device Story

Gemini 16 is a combined PET/CT imaging system; integrates PET and multislice CT gantries within a common housing; utilizes single workstation for operator control. Inputs: PET radiopharmaceutical distribution data and X-ray transmission data. Operation: PET and CT images registered and fused for spatial alignment; CT data used for PET attenuation correction. Used in clinical oncology settings; operated by trained health professionals. Output: Fused PET/CT images for anatomical and functional interpretation. Benefits: Combined anatomical/functional data; reduced scan time; improved attenuation correction speed compared to predicate. System supports integrated or stand-alone PET/CT operation.

Clinical Evidence

Bench testing only. Performance measured in accordance with NEMA NU-2 standards. Compliance with 21 CFR 1020.30 and 1020.33 for radiation safety and IEC 60601-1 series for electrical/mechanical safety.

Technological Characteristics

Combined PET/CT scanner; GSO-based PET detectors; multislice CT capability. Integrated operator console. Compliance: NEMA NU-2, 21 CFR 1020.30/33, IEC 60601-1. Fixed or mobile installation capability.

Indications for Use

Indicated for clinical whole body oncology imaging in patients requiring PET and/or CT diagnostic scans. Used for head, body, and total body imaging by trained health professionals.

Regulatory Classification

Identification

An emission computed tomography system is a device intended to detect the location and distribution of gamma ray- and positron-emitting radionuclides in the body and produce cross-sectional images through computer reconstruction of the data. This generic type of device may include signal analysis and display equipment, patient and equipment supports, radionuclide anatomical markers, component parts, and accessories.

- F. Intended Use:

The device is an imaging system that combines Positron Emission Tomography (PET) and X-ray Computed Tomography (CT). The device produces attenuation and nonattenuation corrected images of the distribution of PET radiopharmaceuticals in the head, body and total body as well as x-ray transmission images of these areas. The PET and CT images are registered and displayed in a "fused" (overlaid in the same spatial orientation) format to provide combined PET and anatomical data at different angles for interpretation by trained health professionals. The PET and CT portions of the system can be used either as an integrated system or as a stand-alone PET or CT system. The device can provide CT data suitable for use in attenuation correction.

Device Description/ Comparison with Predicate Device: G.

The device is a combination Positron Emission Tomography (PET) and X-ray Computed Tomography (CT) scanner that can be utilized in both conventional, fixed installations or mobile environments. The system integrates the two system operator consoles into a single workstation to allow straightforward planning and system operation. The individual PET and the CT gantries remain intact as major subsystem located within a common integrated housing. It can be used in clinical protocols and procedures, which have been clinically conducted in a separate CT system and/or a PET system.

{1}------------------------------------------------

The system is intended for use primarily as a clinical whole body oncology scanner with high-end multislice CT capability and high-end GSO based PET performance. It mechanically separates to allow for the greater flexibility for above three operation modes.

System Performance Test/ Summary of Studies: H.

To minimize electrical, mechanical and radiation hazards, Philips Medical System adheres to recognized and established industry practice.

Radiation safety is assured by compliance and certification to the performance standards for ionizing radiation emitting product, 21CFR 1020.30 and 21CFR 1020.33. The radiation safety product report will be filed in accordance with 21CFR 1002.10 with the Center for Device and Radiological Health.

Electrical and mechanical safety is assured by adherence and certification to the applicable standards in the IEC 60601-1 series. The device performance was measured in accordance with NEMA-NU2 standard.

I. Comparison to Predicate Device

The device is a modification of the currently marketed Gemini PET/CT System (K013521) with design modifications resulting in decreasing patient scan time and improvement in attenuation correction speed. The similarities and differences between the Gemini 16 and the predicate devices are described in detail in Section VI of the premarket notification.

In conclusion, the device is substantially equivalent to the predicate device Gemini (K013521) and the Mx8000IDT (K012009) systems based upon similar intended use, technological comparison, and system performance.
