No
The summary mentions "expert system image interpretation" which could potentially involve rule-based systems, but there is no explicit mention of AI, ML, deep learning, or neural networks. The description focuses on standard image processing and quantification techniques.
No
The device is designed for quantification, display, and analysis of myocardial perfusion and function, providing diagnostic and prognostic information. It does not exert a therapeutic effect on the patient.
Yes
The device quantifies parameters such as myocardial perfusion, ejection fraction, and cardiac mechanic dyssynchrony, and also offers diagnostic information like computer-assisted visual scoring and expert system image interpretation. These functionalities are used to provide insights into a patient's medical condition, which is the definition of a diagnostic device.
Yes
The device description explicitly states it is a "software program" and describes its function as processing and displaying data from existing imaging modalities. It does not mention any accompanying hardware components that are part of the device itself.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The description of the Emory Cardiac Toolbox™ 3.1 clearly states that it processes data from imaging modalities (SPECT, PET, CT) and analyzes images of the heart. It does not analyze biological samples like blood, urine, or tissue.
- The intended use and device description focus on image processing and analysis of in-vivo data. The software quantifies parameters from myocardial perfusion studies and CT coronary angiography, which are procedures performed on a living patient.
- The input modalities are imaging modalities, not laboratory tests. SPECT, PET, and CT are imaging techniques, not methods for analyzing biological specimens.
Therefore, the Emory Cardiac Toolbox™ 3.1 is a medical device used for image processing and analysis in the field of nuclear medicine and cardiology, but it does not fit the definition of an In Vitro Diagnostic device.

Device Description
The Emory Cardiac Toolbox™ 3.1 is used to display gated wall motion and for quantifying parameters of left-ventricular perfusion and function from gated SPECT & PET myocardial perfusion studies. These parameters are: perfusion, ejection fraction, end-diastolic volume, end-systolic volume, myocardial mass, transient ischemic dilatation (TID), and cardiac mechanic dyssynchrony. In addition, the program offers the capability of providing the following diagnostic information: computer assisted visual scoring, prognostic information, expert system image interpretation, and patient specific 3D coronary overlay. The program can also be used for the 3D alignment of coronary artery models from CT coronary angiography onto the left ventricular 3D epicardial surface and for generation of the short axis, vertical, and horizontal long axis tomograms from the SPECT raw data using either filtered backprojection (FBP) or iterative reconstruction (MLEM/OSEM). The Emory Cardiac Toolbox can be used with any of the following Myocardial SPECT Protocols: Same Day and Two Day Sestamibi, Dual-Isotope (Tc-99m/Tl-201), Tetrofosmin, and Thallium, Rubidium-82, N-13-ammonia, FDG protocols, and user defined normal databases. This program was developed to run in the IDL operating system environment which can be executed on any nuclear medicine computer systems which supports IDL and the Aladdin (General Electric) software development environment. The program processes the studies automatically. however, user verification of output is required and manual processing capability is provided.

5. Intended Use and Potential Adverse Effect on Health:
The intended use of this program was to provide the physician with a program which would allow him to determine quantitative analysis of the myocardial perfusion, display wall motion and determine measurements of ejection fraction and ventricular volumes from his patients gated SPECT & PET myocardial perfusion study, obtain visual interpretation scores, prognostic information, expert system interpretation, for the 3D alignment of coronary artery models from CT cornary angiography onto the left ventricular 3D epicardial surface, for the assessment of cardiac mechanic dyssynchrony using phase analysis, and for generation of the short axis, vertical, and horizontal long axis tomograms from the SPECT raw data using either filtered backprojection (FBP) or iterative reconstruction (MLFM/QSEM). This program serves merely as a display and processing program to aid in the diagnostic interpretation of a patients' study. It was not meant to replace or eliminate the standard visual analysis of the gated SPECT & PET study. The physician should integrate all of the patients' clinical and diagnostic information, i.e. patients' history, stress and/or rest EKG, quality control images, visual interpretation of the gated tomographic images, and quantitative results, prior to making his final interpretation. This comprehensive processing technique (as with all diagnostic imaging) is not perfect, and will be associated with some false positive and false negative results. The expected accuracy of the initial program can be found in the multicenter trial results listed in the article by Vansant et al Emoy Cardinc Toolbox™ (CEqual®, EGS™) Version 2.0, Ref. 510(k) #: K992450 and Version 2.1, Ref. 510(k) #: K014033). The accuracy for modifications in version 3.1 for SPECT reconstruction and for evaluation of cardiac mechanic dyssynchrony by phase analysis can be found in Item H (Testing & Validation) of this 510(k) submission. The physician should be aware of the accuracy when integrating the quantistive results for his final interpretation. Therefore, this program has no direct adverse effect on health since the results represent only a part of the information which the

physician will utilize for his final interpretation. interpretation of the study lies with the physician.

6. Marketing History:
There have been several medical device gated SPECT programs marketed in the past which perform similar functions to those performed by the Emory Cardiac Tool Box™ 2.0, 2.1, and 2.6. These programs are all used for the purpose of displaying wall motion and deriving functional parameters for the diagnostic interpretation by a physician. The Emory Cardiac Tool Box™ 3.1 provides additional features for the assessment of cardiac mechanic dvssynchrony using phase anaylsys, and for generation of the short axis, vertical, and horizontal long axis tomograms from the SPECT raw data using either filtered backprojection (FBP) or iterative reconstruction (MLEM/OSEM) which executes in the IDL operating system environment and we believe is substantially equivalent to AutoSPECT Plus developed by ADAC Laboratories K992317 for Emory Reconstruction Toolbox (ERTb™) and GE Vivid 7 Diagnostic Ultrasound System with TSI developed by GE Medical Systems K031663 for Phase Analysis. To our knowledge there have been no safety problems with the AutoSPECT Plus program which has been in the marketplace since October 1, 1999 and with GE Vivid 7 Diagnostic Ultrasound System with TSI which has been which has been in the marketplace since June 9. 2003.
7. Conclusions:
The safety of this program has been determined through the various stages of software development which included the initial design. coding, debugging, testing, and validation. The effectiveness of the initial program, Emory Cardiac Toolbox™ 2.0 has been established in phantom and computer simulations studies, in-house trial validations which included an evaluation of left ventricular functional parameter calculations in 217 patients, and in a multicenter trial validation consisting of 80 patients. In addition, the computer assisted visual scoring, prognosis, expert system, and coronary fusion algorithms were successfully evaluated in 20, 504, 461, and 9 patients respectively.
