No
The summary describes a mechanical innovation (Sliding Gantry) for a standard CT device and does not mention any AI/ML components or image processing capabilities.
No.
The device is described as producing cross-sectional images for diagnostic purposes, which is not a therapeutic function. It does not treat or alleviate any medical condition.
Yes
The device is described as producing "cross-sectional images of the body by computer reconstruction of x-ray transmission data," which are used for diagnostic purposes (e.g., identifying abnormalities, injuries, or diseases within the body). While the text describes the image acquisition, the fundamental output (images of the body) is a tool for diagnosis.
No
The device description clearly details a physical "Sliding Gantry Option" which is a hardware component that integrates precise scan control and horizontal movement into the CT gantry itself. This is not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for producing cross-sectional images of the body using x-ray transmission data. This is a diagnostic imaging procedure performed on the patient, not a test performed on biological samples outside the body.
- Device Description: The description details the mechanical aspects of the CT scanner and its sliding gantry option, focusing on how it acquires images of the patient.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any other components typically associated with in vitro diagnostics.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This CT device falls under the category of medical imaging devices used for in vivo diagnosis.
N/A
Intended Use / Indications for Use
The CT device with Sliding Gantry Option is intended 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. (*Spiral planes: the axial planes resulted from the continuous rotation of detectors and x-ray tube and the simultaneous movement of the Sliding Gantry).

Device Description
The Sliding Gantry option is designed to allow whole body x-ray computed tomography scanning on a single patient that can be performed on different types of patient tables in different environments. The Sliding Gantry Option integrates the function of precise scan control driven horizontal movement, which is usually a function of the dedicated CT-table, into the CT gantry itself. The original CT gantry is mounted on a rail system and a scan control system moves the gantry relative to the table, instead of moving the table relative to the gantry.
