Indications for Use
The Symbia Pro.specta systems are radiological imaging systems that combines 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 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 images 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 registered 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 support, radionuclide anatomical markers, component parts, and accessories. The SPECT and CT images may be transferred to other systems for radiation therapy planning or additional uses.
Device Story

## Device Description:
The Siemens Symbia Pro.specta Q3, X3 and X7 systems consists of Single-Photon Emission Computed Tomography (SPECT) scanner and integrated hybrid x-ray Computed Tomography (CT) and SPECT scanner.
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.

Siemens Symbia Pro.specta Q3, X3, X7, Symbia Pro.specta VA40 Family Special 510(k) Premarket Notification
The system can be used as an integrated SPECT and CT modality while also enabling independent functionality of SPECT and CT as stand-alone diagnostic imaging devices.
Siemens Symbia Pro.specta systems maintains the same intended use and indications for use as the commercially available Symbia Pro.specta VA30A systems (K243186).
Symbia Pro.specta systems are hybrid modality imaging systems comprised of two separate but integrated components: a gamma camera (SPECT) and a CT. The gamma camera is based on hardware and software features that generate nuclear medicine images based on the uptake of radioisotope tracers in a patient's body. The CT system (spiral CT) is designed 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.
The combination of SPECT and CT in a single device has several benefits. The SPECT subsystem images biochemical function while the CT subsystem images anatomy. The combination enables scans that not only indicate function, e.g., how active a tumor is, but precise localization, e.g., the precise location of that tumor in the body.
In addition, CT can be used to correct for the attenuation in SPECT acquisitions. Attenuation in SPECT is an unwanted side effect of the gamma rays scattering and being absorbed by tissue. This can lead to errors in the final image. The CT directly measures attenuation and can be used to create a 3D attenuation map of the patient which can be used to correct the SPECT images. The SPECT-CT scanner can be used to image and track how much dose was delivered to both the target and the surrounding tissue.
The systems consist of display equipment, data storage devices, patient and equipment supports and component parts and accessories.
Symbia Pro.specta VA40 release is the product name for the addition of features to the approved Symbia Pro.specta VA30A Family (K243186). The Symbia Pro.specta VA40A devices are based on the Symbia Pro.specta VA30A Family. The difference lies in the additional features/changes. The Intended Purpose and fundamental scientific technology remain unchanged.
Proposed modifications in Symbia Pro.specta VA40 include:
- Single Button Positioning for CT for daily QA
- IQ-SPECT cardiac improved image quality
- Retrospective 2D (formerly known as Enhanced QCI)
- Enhanced 2D Data Format (aka Legacy Data Format)
- Extended ECL for Low Energy Isotopes
- User Defined Isotopes for Broad Quantification
