### Device Description:

The Siemens Symbia systems consist of Single Photon Emission Computed Tomography (SPECT) scanners and integrated hybrid X-Ray Computed Tomography (CT) and SPECT scanners. The SPECT subsystem images and measures the distribution of radiopharmaceuticals in humans for the purpose of determining various metabolic (molecular) and physiologic functions within the human body and integrates CT's anatomical detail for precise reference of the location of the metabolic activity. The CT component produces cross-sectional images of the body by computer reconstruction of X-Ray transmission data from either the same axial plane taken at different angles or spiral planes taken at different angles. The system can be used as an integrated SPECT and CT modality while also enabling independent functionality of SPECT and CT as standalone diagnostic imaging devices.

- Upgraded software syngo MI Applications VB20A which incorporates expansions of commercially available xSPECT Quantification (Symbia 5.0 K131634)
- Implementation of commercially marketed CT software, (K151752, 'CT ● SOMARIS/5 VC30')
- Integration of commercially marketed software application syngo TrueD ● (K101749) for viewing, manipulation, 3D visualization and comparison of medical images from multiple imaging modalities.
- . Hardware upgrade; four additional touchpad sensors to cover detectors' light rails and L-arms

### Intended Use:

The Symbia Intevo Excel, Intevo series and T series are radiological imaging systems that combine a single photon emission computed tomography (SPECT) camera system for nuclear medicine images, and a computed tomography (CT) camera system for x-ray images. The Symbia E series, Symbia S, Evo, and Evo Excel systems are SPECT camera systems.

The SPECT system is intended to detect the location and distribution of gamma ray radionuclides in the body and produce cross-sectional images through computer reconstruction of the data, and the CT system is intended to produce cross-sectional imaqes of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. The nuclear medicine images and the x-ray images may be reqistered and displayed in a fused format (overlaid in the same orientation) for the anatomical localization of the nuclear medicine data (that is, distribution of radiopharmaceuticals).

The SPECT and CT portions of the system may be used independently or in combination, and may include signal analysis and display equipment, patient and equipment supports,

{6}------------------------------------------------

radionuclide anatomical markers, component parts, and accessories. The SPECT and CT imaqes may be transferred to other systems for radiation therapy planning or additional uses.

### Indications for Use:

The Siemens Symbia series is intended for use by appropriately trained health care professionals to aid in detecting, localizing, diagnosing, staging and restaging of lesions, tumors, disease and orqan function for the evaluation of diseases and disorders such as, but not limited to, cardiovascular disease, neurological disorders and cancer. The images produced by the system can also be used by the physician to aid in radiotherapy treatment planning and interventional radiology procedures.

SPECT: To detect or image the distribution of radionuclides in the body or organ, using the following techniques: planar imaging, whole body imaging, tomographic imaging for isotopes with energies up to 588keV

CT: The CT component is intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from either the same axial plane taken at different angles or spiral planes taken at different angles.

SPECT+CT: Perform CT scans and nuclear imaging studies with the same instrument. To obtain attenuation corrected images and to provide registration of anatomical and physiological images within the patient's anatomy.

Software: The MI Applications software is a display and analysis package intended to aid the clinician in the assessment and quantification of pathologies taken from SPECT, PET, CT and other imaging modalities.

### Technological Characteristics:

Symbia 6.5 systems are based on the commercially available Symbia 6.0 (K142006). The software updates are based on the same fundamental technology of the xSPECT quantification in Symbia SPECT/CT predicate components. SPECT detector, existing collimators, and CT performance specifications do not change between the commercially available Symbia 6.0 systems and Symbia 6.5 systems. The syngo TrueD software application, incorporated into the updated software, is commercially available (K101749).

### Performance Testing:

Performance testing for the CT subsystem was included in the original premarket notification for the CT subsystems and there have been no changes affecting this testing.

Symbia 6.5 is designed in accordance with the 60601-1 series including all relevant collateral standards general (IEC 60601-1, 1-2, 1-3, etc) and specific (IEC 60601-2-44). Performance testing is conducted according to NEMA NU-1:2012. All Performance testing met the predetermined acceptance values.
