(154 days)
Yes
The device description explicitly mentions the introduction of optional features using "Deep Learning based model" and "DL-based automatic kidney segmentation algorithm."
No
Explanation: The device is a software system intended for image processing, display, and analysis for diagnostic purposes. While some applications aid in calculating a therapeutic dose (Q.Liver application for SIRT treatment) or assessing quantities related to disease progression, the system itself does not provide therapy or alter the patient's body in a therapeutic way. Its primary function is to provide information for clinical diagnostic purposes.
Yes
The "Intended Use / Indications for Use" section explicitly states that the system is for "clinical diagnostic purposes" and that various applications "may assist in detection," "may aid physicians in diagnosis," or "may add information to physicians using Myocardial Perfusion Imaging for the diagnosis of Coronary Artery Disease (CAD)," all of which are indicative of a diagnostic device.
No
The device description explicitly states that the system's hardware components "may include computer workstations, communications devices, video monitors, data storage and hardcopy devices." While software is a key component, the system is not solely software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze biological samples (like blood, urine, tissue) outside the body. This device processes and analyzes medical images acquired from within the patient's body using imaging modalities like Nuclear Medicine (NM), PET, CT, and MR.
- The intended use clearly describes processing and analyzing imaging data for clinical diagnostic purposes. While the results of the analysis may aid in diagnosis, the device itself is not performing a test on a biological specimen.
The device is a medical image processing and analysis software system used by medical professionals to interpret imaging data. This falls under the category of medical devices, but not specifically In Vitro Diagnostics.
No
The input lacks any mention of the FDA reviewing, approving, or clearing a PCCP for this device. The 'Control Plan Authorized (PCCP) and relevant text' section explicitly states 'Not Found'.
Intended Use / Indications for Use
The system is intended for use by Nuclear Medicine (NM) or Radiology practitioners and referring physicians for display, processing, archiving, printing, reporting and networking of NMI data, including planar scans (Static, Whole Body, Dynamic, Multi-Gated) and tomographic scans (SPECT, Gated SPECT, dedicated PET or Camera-Based-PET) acquired by gamma cameras or PET scanners. The system can run on dedicated workstation or in a server-client configuration. The NM or PET data can be coupled with registered and/or fused CT or MR scans, and with physiological signals in order to depict, localize, and/or quantify the distribution of radionuclical structures in scanned body tissue for clinical diagnostic purposes.
The DaTQUANT optional application enables visual evaluation of 1231-ioflupane (DaTscanTM) images. DaTQUANT Normal Database option enables quantification relative to normal population databases of 1231ioflupane (DaTscanTM) images. These applications may assist in detection of loss of functional dopaminergic neuron terminals in the striatum, which is correlated with Parkinson disease.
The O.Lung application may aid physicians in:
· Diagnosis of Pulmonary Embolism (PE), Chronic Obstructive Pulmonary Disease (COPD), Emphysema and other lung deficiencies.
• Assess the fraction of total lung function provided by a lobe or whole lung for Lung cancer resection requiring removal of an entire lobe, bilobectomy, or pneumonectomy.
The Q.Brain application allows the user to visualize and quantify relative changes in the brain's metabolic function or blood flow activity between a subject's images and controls, which may be resulting from brain functions in: · Epileptic seizures
· Dementia. Such as Alzheimer's disease, Lewy body dementia, Parkinson's disease with dementia, and frontotemporal dementia.
- · Inflammation
- · Brain death
- · Cerebrovascular disease such as Acute stroke, Chronic and acute ischemia
· Traumatic Brain Injury (TBI)
When integrated with the patient's clinical and diagnostic information may aid the physician in the interpretation of cognitive complaints, neuro-degenerative disease processes and brain injuries.
The Alcyone CFR application allows for the quantification of coronary vascular function by deriving Myocardial Blood Flow (MBF) and then calculating Coronary Flow Reserve (CFR) indices on data acquired on PET scanners and on stationary SPECT scanners with the capacity for dynamic SPECT imaging. These indices may add information to physicians using Myocardial Perfusion Imaging for the diagnosis of Coronary Artery Disease (CAD).
The Exini Bone application is intended to be used with NM bone scans for the evaluation of adult male patients with bone metastases from prostate cancer. Exini Bone quantifies the selected lesions and provides a Bone Scan Index value as adjunct information related to the progression of disease.
The Q.Liver application provides processing, quantification, and multidimensional review of Liver SPECT/PET and CT images for display, segmentation, and a calculation of the SPECT 'liver to lung' shunt value and the patient's Body Surface Area (BSA) for use in calculating a therapeutic dose for Selective Internal Radiation Therapy (SIRT) treatment using a user defined formula.

The Xeleris V Processing and Review System has identical or equivalent technological characteristics as its predicate and reference devices. The changes and the different technological characteristics do not raise new or different questions of safety and effectiveness. The software was developed, verified, and validated under GE Healthcare's QMS including software development lifecycle.
Design Control Testing: Testing
Summary
Design Control Testing:
Xeleris V and its clinical applications successfully completed all design control testing per GE Healthcare's quality system and also verified compliance with the relevant standards (i.e. NEMA PS3.1 - 3.20, IEC62304). The testing did not raise any new safety questions or identify any new risks. Xeleris V is designed and will be manufactured under the Quality System Regulations of 21CFR 820 and ISO 13485. The following quality assurance measures were applied to the development of the system:
- Risk Analysis
- · Requirements Reviews
- · Design Reviews
- · SW Development Lifecycle
- Testing on Unit Level (Module Verification)

There are three water droplets or splashes emanating from the top and sides of the circle, giving the logo a dynamic and fluid appearance. The color scheme is primarily blue and white.
- · Integration Testing (System Verification)
- · Performance Testing (Verification)
- Safety testing (Verification)
- · Simulated Use Testing (Validation)
The testing and their results do not raise different questions of safety and effectiveness than the predicate device. GE believes Xeleris V is of comparable type and substantially equivalent to the predicate and reference devices, and hence is safe and effective for its intended use. The substantial equivalence was also based on software documentation for a "Moderate" level of concern device.
Summary of Additional Testing:
In addition to the verification and validation testing successfully completed as required by GE Healthcare's quality system, additional engineering and clinical performance testing was performed to provide the requisite data to demonstrate performance and substantiate claims. This testing included:
Engineering testing including clinical datasets and clinician participation.
- · Demonstration of clinical outputs, workflow, and tools.
- Scientific testing for algorithm performance and claims substantiation.
- · Algorithm clinical performance testing using test datasets of representative clinical exams where the ground truth and evaluations were performed by clinicians.
Clinical Evaluation
Xeleris V did not require clinical studies to support the determination of equivalence. However, the performance testing for the DL-based algorithms for kidney segmentation and lung fissure segmentation evaluates and demonstrates each algorithm's performance and uses test datasets of representative clinical exams.
The test datasets were comprised of representative clinical exams that were manually segmented by experienced NM Physicists and Physicians and were used as ground truth. The NM Physicists and Physicians also performed the algorithm evaluation. They reviewed the segmentation results and scored them using a 5-point Likert scale.
The scientific methods used to evaluate the effectiveness of Xeleris V are acceptable and support the determination of substantial equivalence.
Substantial The Substantial Equivalence of the proposed device has been demonstrated by:
- Equivalence
- Review of the proposed Indications for Use shows that they are substantially equivalent to the predicate device's, also with consideration of the reference devices. Xeleris V's Indications for Use do not create a new Intended Use.

- The device description and the comparison of device characteristics show that Xeleris V's has identical or equivalent technological characteristics as its predicate and reference devices.
- The testing (engineering and clinical) demonstrates the effectivity of Xeleris V for its intended purpose.
- . The changes and the different technological characteristics do not raise new or different questions of safety and effectiveness. The proposed device is as safe and effective as the legally marketed predicate device as demonstrated by the:
- o Software verification and validation for a Moderate level of concern, without unexpected results;
- o Development under GE's quality management system, design control activities including risk management;
- o Device labeling; and
- o Engineering and clinical testing without unexpected results.
- Xeleris V's Indications for Use do not create a new Intended Use. Xeleris V has Conclusion: identical or equivalent technological characteristics as its predicate device.
Xeleris V was developed under GE Healthcare's quality system. Design verification testing, along with bench and clinical testing demonstrate that Xeleris V is substantially equivalent and hence as safe and as effective as the legally marketed predicate device. GE's quality system's design, verification, and risk management processes did not identify any new hazards, unexpected results, or adverse effects stemming from the changes to the predicate.
Based on development under GE Healthcare's quality system, the successful verification, engineering bench and clinical testing, GE Healthcare believes that Xeleris V is substantially equivalent to the predicate device and hence is safe and effective for its intended use.
