The Siemens Symbia series is intended for use by appropriately trained health care professionals to aid in detecting, localizing, diagnosing, staging and restaging of lesons, turnors, disease and organ function for the evaluation of diseases and disorders such as, but not limited to, cardiovascular disease, neurological disorders and cancer. The innages produced by the system can also be used by the physician to aid in radiotherapy to atmont 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 isotopns 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 PERT CT and other imaging modalities.
The Siemens Symbia® system is combined X-Rav Computed Tomography (CT) and Emission Computed Tomography (SPECT) scanners that provide registration and fusion of high resolution physiologic and anatomic information.
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 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 utilizes the CT for fast attenuation correction maps for SPECT studies and precise anatomical reference for the fused SPECT and CT images.
The system maintains independent functionality of the CT and SPECT devices, allowing for single modality CT and / or SPECT diagnostic imaging.
The Symbia E and Symbia S series are gamma cameras used to view and analyze images of the human body and the distribution of administered radionuclides.
The Symbia T series have an additional CT system designed to produce crosssectional 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 Symbia T series allows healthcare facilities to carry out SPECT and CT studies using the same instrument.
The MI Workplace is a software workstation for use with nuclear medicine applications. The MI Applications software functions as the primary user interface for acquiring, viewing, manipulating, post-processing and archiving images from the Siemens family of dedicated SPECT, PET and SPECT/CT and PET/CT systems.

The provided 510(k) summary for the Symbia 4.0 does not include a detailed study or acceptance criteria table typically found in performance testing sections. This document primarily focuses on demonstrating substantial equivalence to predicate devices and detailing the device's indications for use and safety measures.
Therefore, the requested information regarding acceptance criteria, reported device performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, and ground truth establishment for a specific study is not available within this document.
The document states:
- "Risk Management is ensured via a risk analysis in compliance with ISO 14971 to identify and provide mitigation to potential hazards beginning early in the design cycle and continuing throughout the development of the product."
- "Siemens Medical Solutions, USA Inc. adheres to recognized and established industry standards such as IEC 60601-1 series and 21 CFR 1020.30 and 21 CFR 1020.33 to minimize electrical, mechnanical and radiation hazards."
- "Siemens considers that the proposed systems do not introduce new safety concerns, and is substantially the same in design, materials, energy sources and technology as the currently marketed systems. Siemens believes that the Symbia 4.0 systems are substantially equivalent to the predicate devices."
This indicates that Siemens is relying on its adherence to established standards and the substantial equivalence argument, rather than presenting a performance study with specific acceptance criteria in this summary.
In summary, the detailed study information requested is not present in the provided 510(k) summary.
§ 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)
