Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The FCT iStream system is a Computed Tomography (CT) system. It uses X-rays to create images of the inside of the body. It acquires images directly from the patient's body, not from a sample taken from the body.
- Intended Use: The intended use describes acquiring images of the whole body, including the head, for diagnostic purposes and interventional guidance. This is a direct imaging modality, not a test performed on a biological sample.
Therefore, the FCT iStream system falls under the category of medical imaging devices, not in vitro diagnostics.
N/A
Intended Use / Indications for Use
The FCT iStream system is indicated to acquire axial volumes of the whole body including the head. Images can be acquired in axial, helical, or dynamic modes. The FCT iStream system can also be used for interventional needle guidance. Volume datasets acquired by an FCT iStream system can be post-processed in the FCT iStream system to provide additional information. Post-processing capabilities of the FCT iStream software include multi-planar reconstruction (MPR), and volume rendering. Volume datasets acquired by an FCT iStream system can be transferred to external devices via a DICOM standard interface.
The Low Dose CT Lung Cancer Screening Option for the FCT iStream system is indicated for using low dose CT for lung cancer screening.

Device Description
The FCT iStream is a multi-slice computed tomography system that uses x-ray data to produce cross-sectional images of the body at various angles.
The FCT iStream X-ray source is designed to enable the continuous emission of fan-beam Xrays, and the solid state detector unit is positioned opposite the X-ray source to measure the intensity distribution of the X-rays. The total number of detector channels is 888 channels x 64 rows, and all of the rows are used as 64-slice portions. Note that the magnification factor of the X-ray system is 1.77 and that the width of the opening of each channel in the center of the measuring area is 0.6 mm. These factors, along with the focal spot size, affect spatial resolution.
The collected data is then reconstructed into cross-sectional images by a high-speed reconstruction sub-system. The images are displayed on a Computer Workstation, stored, printed, and archived as required. The workstation is based on current PC technology using the Windows™ operating system.
The FCT iStream system consists of a Gantry, Operator's Workstation, Patient Table, High-Frequency X-ray Generator, and accessories.

Device Description
Function
The FCT iStream is a multi-slice computed tomography system that uses x-ray data to produce cross-sectional images of the body at various angles.
Scientific Concepts
The FCT iStream X-ray source is designed to enable the continuous emission of fan-beam Xrays, and the solid state detector unit is positioned opposite the X-ray source to measure the intensity distribution of the X-rays. The total number of detector channels is 888 channels x 64 rows, and all of the rows are used as 64-slice portions. Note that the magnification factor of the X-ray system is 1.77 and that the width of the opening of each channel in the center of the measuring area is 0.6 mm. These factors, along with the focal spot size, affect spatial resolution.
The collected data is then reconstructed into cross-sectional images by a high-speed reconstruction sub-system. The images are displayed on a Computer Workstation, stored, printed, and archived as required. The workstation is based on current PC technology using the Windows™ operating system.
Physical and Performance Characteristics
The FCT iStream system consists of a Gantry, Operator's Workstation, Patient Table, High-Frequency X-ray Generator, and accessories. The system performance is similar to the predicate device.
Performance Comparison
Evaluations were conducted for IntelliODM, iTilt and for features that were removed from the subject device to the predicate device (see table below).
Removed Features
| 1 | Gantry tilt mechanism |
|---|---|
| 2 | Shuttle Scan and Helical Shuttle Scan |
| 3 | Adaptive Filter function (a part of Image analysis function) |
| 4 | Segmentation function (a part of Image analysis function) |
| 5 | Retouch function (a part of Image analysis function) |
| 6 | Image Analysis on external PC |
| 7 | Motion corrected reconstruction (Cardio Still Shot) |
| 8 | Assist in patient positioning using camera (AutoPositioning) |
The evaluation results confirm the performance characteristics of FCT iStream are comparable to the predicate device and support our conclusion that the subject system is substantially equivalent.

| Physical characteristics | Image: FCT iStream Phase 1 | Image: SCENARIA View 4.2 | Gantry | Different specifications do not constitute a new intended use. There are no significant changes
in technological characteristics. The gantry and detector design were based on the same
technology as the predicate device. |
| Gantry | The specifications of the device are different, the minimum scan time of this device is not as
short as the predicate device. This change does not affect overall technological characteristics
compared to the predicate device.
This gantry does not have a tilt mechanism compared to the predicate device. If it is necessary
to take a tilted image, it will use the iTilt function to create an equivalent MPR image. So it will
not affect the effectiveness of the system. Also, this does not affect the safety of this device
compared to the predicate device.
The specifications of the device are different, the size and the weight of the gantry of this
device are different from the predicate device. However, as the device weighs less and has a
smaller footprint than the predicate device, we judge that these changes do not impact the
intended use.
The monitor in the center of the gantry is for display only. Since the information required for the
intended use of the device is displayed. | | Detector | Different specifications do not constitute a new intended use. There are no significant changes
in technological characteristics. The gantry and detector design were based on the same
technology as the predicate device. |
| Detector | There are no differences between the two systems. | | X-ray Tube | These subsystems have the same level of general effectiveness as the predicate device based
on the performance test results. For safety, these items are controlled and tested according to
same regulations and/or standards as the predicate device. |
| X-ray Tube | The X-ray tube of this device is different from the predicate device only in heat capacity. The X-ray
tube focal spot and general performance characteristics are the same as the predicate device. | | X-ray Generator | This item conforms to IEC 60601-2-44:2009+A1:2012+A2:2016 requirements for CT systems
and has the same level of general effectiveness as the predicate device based on the
performance test results. For safety, this item is controlled and tested according to same
regulations and/or standards as the predicate device. |
| X-ray Generator | The specifications of the device are different, to match the performance specifications of this
device and conforms to IEC 60601-2-44:2009+A1:2012+A2:2016 requirements for CT systems.
The kVp and mA output of the device is comparable to the predicate device. | | Patient Table | Different specifications do not constitute a new intended use. There are no significant changes
in technological characteristics. The table travel and weight capacity characteristics are
generally equivalent to the predicate device. For safety, this item is controlled and tested
according to same regulations and/or standards as the predicate device. |
| Patient Table | The specifications of the device are different, the size and the weight of the table of this device are
different from the predicate device. However, as the device weighs less and has a smaller
footprint than the predicate device, we judge that these changes do not impact the intended use. | | Operator's console | Operator's console has a slight difference in capacity of the predicate device, but the maximum
number of storage images remains the same. For safety, this item is controlled and tested
according to same regulations and/or standards as the predicate device. |
| Operator's console | Operator's console has a slight difference in SSD capacity of the predicate device, but the
maximum number of storage images remains the same. | | Scanning, Reconstruction | Different specifications do not constitute a new intended use. There are no significant changes
in technological characteristics. The design criteria for these elements were set to allow
comparable performance to the predicate device. The performance of these sub-systems does
not substantially affect the effectivity and safety as compared to the predicate device. |
| Scanning, Reconstruction | The iTilt function uses MPR technology to create a tilt image immediately after scanning. This
function uses the same technology as the existing MPR function, and does not affect overall
technological characteristics compared to the predicate device. | | Performance | There are no substantial differences in this category based on the performance test results. |
| Performance | There is a difference in the Low-contrast mm at % ≤ 4 rads. | | Dose Controls | Different specifications do not constitute a new intended use. There are no significant changes
in technological characteristics. For safety, these items are controlled and tested according to
same regulations and/or standards as the predicate device. |
| Dose Controls | While this device is not equipped with a small bow-tie filter, the normal bow-tie filter provides
generally equivalent performance to the predicate device and does not substantially impact the
effectivity and safety of this device.
Intelli IPV is no change in the algorithm, but the heat capacity is reduced from 7.5MHU to 6MHU,
so the effect will be different. However, this does not impact the effectivity and safety of this device
as compared to the predicate device. | | Features | Different specifications do not constitute a new intended use. There are no significant changes
in technological characteristics and the feature set of the device is generally equivalent to the
predicate device. |
| Features | IntelliODM is a feature that uses IntelliEC technology to reduce X-ray exposure from the patient's
head, reducing direct radiation dose to sensitive organs. | | | |
