The Siemens Symbia Intevo Bold is intended for use by appropriately trained health care professionals to aid in detecting, localizing, diagnosing, staging of lesions, tumors, disease and organ 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: The SPECT component is intended to detect or image the distribution of radionuclides in the body or organ (physiology), using the following techniques; Planar imaging, and tomographic imaging for isotopes with energies up to 588 keV.
CT: The CT component is intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data (anatomy) from either the same axial plane taken at different angles or spiral planes take at different angles.
SPECT+CT: The SPECT and CT components used together acquire SPECT/CT images can be corrected for attenuation with the CT images, and can be combined (image registration) to merge the patient's physiological (SPECT) and anatomical (CT) images.
Software: the syngo MI Applications software is a display and analysis package intended to aid the clinician in the assessment and quantification of pathologies in images produced from SPECT, PET, CT and other imaging modalities.
The Siemens Symbia Intevo Bold consist of Sinqle 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.
Symbia Intevo Bold implements software version syngo MI Applications VB20A.
Modifications include:
-
Incorporation of the commercially available SOMATOM Scope Power CT system (K151749)
-
Software updates include modifications to support features available with the CT and SPECT subsystems
-
Expansion of commercially available xSPECT Quant (Symbia 5.0 K131634) to support quantification of additional isotopes
-
Four additional touchpad sensors to cover detectors' light rails and L-arms.
Commercially available xSPECT Quant (Symbia 5.0 K131634) was expanded to support quantification of additional isotopes such as I-123 and In-111. For these isotopes, dose calibrator independent quantification is enabled by a NIST traceable sensitivity calibration method. In addition, cross calibration capabilities were added to remove dose calibrator biases and variations in SUV calculations. The system allows cross calibration of multiple dose calibrators and, once calibrated, automatically adjusts for their biases.
In addition to dose calibrator independent quantification for I-123 and In-111 support for dose calibrator dependent quantification was added for a broad range of SPECT isotopes and collimators (Broad Quantification). Dose calibrator dependent quantification neither supports NIST traceable calibration nor cross calibration and relies on sensitivity measurements based on a local dose calibrator.
Here's an analysis of the acceptance criteria and study that proves the device meets them, based on the provided text:

§ 892.1200 Emission computed tomography system.
(a)
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.(b)
