Intended Use

The Discovery CT590 RT/Optima CT580 Computed Tomography Systems are intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data taken at different angles and planes, including Axial, Cine, Helical (Volumetric), and Gated (Respiratory and Cardiac) acquisitions for all ages. These images may be obtained either with or without contrast. This device may include signal analysis and display equipment, patient and equipment supports, components and accessories. This device may include data and image processing to produce images in a variety of trans-axial and reformatted planes. Further the images can be post processed to produce additional imaging planes or analysis results. The GE Discovery CT590 RT/Optima CT580 Computed Tomography Systems are indicated for head, whole body, and vascular X-ray Computed Tomography applications in patients of all ages. The device output is a valuable medical tool for the diagnosis of disease, trauma, or abnormality and for planning, guiding, and monitoring therapy. The system is capable of assisting with minimally invasive procedures such as biopsy and ablation of tumors and pathology. The system allows imaging of Bariatrics patients, up to and including the morbidly obese population (BMI > 40). The system can acquire CT anatomical images that are clinically useful in the simulation and planning of radiation therapy for the treatment of cancer. If the Deviceless 4D option is included on the system, the system can be used to efficiently provide and display CT images of all phases of a breathing cycle for the evaluation of respiration-induced motion of the chest for use with therapy planning and simulation. The software calculates the breathing period to determine the Cine acquisition duration and the cine time between images which is automatically imported to the 4D cine acquisition. The software then uses information derived from the imaging for the binning process.

Device Story

CT system (gantry, table, console, computer) acquires X-ray transmission data for cross-sectional imaging. Deviceless 4D (D4D) software option enables 4D imaging without external respiratory monitors. D4D uses 'SmartBreath' scout scan to determine breathing cycle; automatically sets Cine scan parameters; uses internal anatomic features from Cine scans for image binning; temporally registers features to breathing cycle. Used in clinical/RT settings by trained operators. Output: CT images (axial, cine, helical, gated) used by clinicians for diagnosis, therapy planning, and guidance. Benefits: efficient 4D imaging, reduced motion artifacts, improved RT planning.

Clinical Evidence

No clinical data. Bench testing only. Evaluated using commercially available breathing phantom with anatomical features to compare SmartBreath periodicity capture against external gating devices. Clinical datasets from internal database used to compare D4D binning/measurement against Advantage 4D predicate. Statistical analysis (scatter plots, Bland-Altman, correlation) demonstrated equivalent performance.

Technological Characteristics

16-slice CT system; gantry, table, console, computer, PDU. Compliant with UL60601-1, IEC 60601-1, NEMA XR-25, 21CFR Subchapter J. Software-based image reconstruction and D4D binning. Connectivity via standard interfaces. Sterilization not applicable (imaging system).

Indications for Use

Indicated for head, whole body, and vascular CT applications in patients of all ages, including bariatric/morbidly obese patients (BMI > 40). Used for diagnosis of disease, trauma, or abnormality; planning, guiding, and monitoring therapy; minimally invasive procedures (biopsy, ablation); and radiation therapy simulation/planning. Deviceless 4D option indicated for evaluating respiration-induced chest motion.

### Marketed Devices:

The Discovery CT590 RT and Optima CT580 with Deviceless 4D option is of comparable type and substantially equivalent to GE Healthcare's currently marketed Computed Tomography X-ray Systems Discovery CT590 RT/ Optima CT580 (K093581) and 4D post-processing device Advantage 4D (K032915). The commercial names currently used in the US market are any of the following configuration names: Discovery CT590 RT and Optima CT580, Optima CT580 RT, or Optima CT580 W and will remain unchanged.

# Device Description:

### Deviceless 4D Option (D4D)

Deviceless 4D is a software option used for capturing the respiratory cycle and binning the image such that the target motion may be obtained for treatment planning. Deviceless 4D has the same intended use and clinical output of Advantaae 4D (A4D,K032915) which was included in the cleared Discovery CT590 RT/ Optima CT580 (K093581) CT system. Deviceless 4D is an alternative and efficient solution for 4D imaging and virtual simulation without the need for an external respiratory monitoring device.

Deviceless 4D first uses a "scout-like" scan type called "SmartBreath" to determine the stable breathing cycle period that is then automatically implemented into the scan parameters for the Cine scans.

D4D incorporates a design that uses internal anatomic features of the respiratory cycle obtained during the Cine scans for image binning. These features are temporally registered to the actual breathing cycle.
