System Overview

This chapter provides a description of the C7 XR OCT Imaging System and its components. Included in this chapter are: •

System features.

•

System components, including the System in Cart, the System Display, and the DOC.

•

Indications for use.

LightLab C7 XR OCT Imaging System Features Optical Coherence Tomography (OCT) is an imaging modality that utilizes fiber-optic technology. The C7 XR OCT Imaging System uses optical imaging catheters that emit near-infrared light to produce high-resolution real-time images. The wavelengths and bandwidths of infrared light are far higher than medical ultrasound signals, resulting in greatly increased image resolution. CAUTION: Medical personnel who use the C7 XR OCT Imaging System must be aware of the system’s limitations. Only trained investigators can determine if the C7 XR use is appropriate. Be sure to read Chapter 12 “Safety Information”, before operating the imaging system for the first time. In addition to controlling basic imaging functions, the C7 XR OCT Imaging System lets you: •

Acquire, save and subsequently retrieve images for review.

•

Acquire and review images in L-Mode (lateral view).

•

Overlay color maps to optimize contrast resolution.

•

Enlarge a defined area of interest (zoom).

•

Make measurements and calculations.

•

Add text annotations.

System Overview C7 XR Components •

Play back and edit images with a full range of playback and editing capabilities.

•

Export still images and movies in raw OCT format or in standard AVI, TIFF, JPEG, BMP, or DICOM formats.

•

Import LightLab OCT format images and review and edit them with full OCT review and edit capability.

•

Perform basic file management functions.

C7 XR Components The LightLab C7 XR OCT Imaging System includes the following components1, integrated into a mobile cart: •

An imaging engine.

•

Two monitors.

•

A Drive-motor and Optical Controller (DOC).

•

An isolation transformer.

•

A computer, a keyboard, and a mouse.

CAUTION: The computer is an integral part of the C7 XR OCT Imaging System and its hardware and software must not be modified in any way by the customer. Making such modifications may interfere with correct operation and will void system warranties. See Chapter 13 “System Specifications” for important classification information for components.
