Second, the software quantifies absolute rest and stress myocardial perfusion per unit tissue (cc/min/gm), Coronary Flow Reserve (CFR) as the stress/rest perfusion ratio and the Coronary Flow Capacity combining CFR and stress perfusion, all on a pixel basis for regional and global values. HeartSee and the predicate K231731 also display stress subendocardial to subepicardial ratio and subendocardial stress to rest ratio on relative activity tomograms, and stress relative topogram maps expressed as a fraction of maximum cc/min/g. called relative stress flow (RSF). Archiving output data is supported for clinical diagnostics, quality control and research. In addition to these established measurements of perfusion in cc/min/g, CFR and CFC, HeartSee has software for determining left ventricular ejection fraction (EF) by PET-CT using Rb-82 compared to EF.

The Siemens Symbia Pro.specta VA30A Family 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. 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 VA30A Family maintains the same intended use and indications for use as the commercially available Symbia Pro.specta VA20A family (K231102). Symbia Pro.specta VA30A Family 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 VA30A release is the product name for the addition of features to the approved Symbia Pro.specta VA20A Family (K231102). The Symbia Pro.specta VA30A devices are based on the Symbia Pro.specta VA20A Family. The difference lies in the additional features/changes. The Intended Purpose and fundamental scientific technology remain unchanged. Proposed new features in Symbia Pro.specta VA30 include: - Cardiac Quantification - High Speed Mode - . NM Remote Reconstruction on myExam Satellite #### Other changes: - Scanning improvements - Recon improvements ● - General software improvements ● - Miscellaneous improvements ●
