Intended Use

The Discovery XR656 HD is intended to generate digital radiographic images of the skull, spinal column, chest, abdomen, extremities, and other body parts in patients of all ages. Applications can be performed with the patient sitting, standing, or lying in the prone or supine position and the system is intended for use in all routine radiography exams. Optional image pasting function enables the operator to stitch sequentially acquired radiographs into a single image. The Discovery XR656 HD incorporates AutoGrid, which is an optional image processing software installed as a part of the systems Helix image processing software. AutoGrid can be used in lieu of an anti-scatter grid to improve image contrast in general radiographic images by reducing the effects of scatter radiation. When the VolumeRAD option is included on the system can generate tomographic images of human anatomy including the skull, spinal column, chest, abdomen, extremities, and other body parts in patients of all ages. When the VolumeRAD option is used for patients undergoing thoracic imaging, it is indicated for the detection of lung nodules. VolumeRad generates diagnostic images of the radiologist in achieving superior detectability of lung nodules versus posterior and left lateral views of the chest, at a comparable radiation level. The device is not intended for mammographic applications.

Device Story

Stationary digital X-ray system; generates radiographic and tomographic images of human anatomy. Inputs: X-ray projections acquired via overhead tube assembly and digital detectors. Operation: Tube sweeps over patient (up to 40 degrees) to capture up to 60 low-dose projections; system reconstructs slices (min 1mm thickness) using filtered back projection (FBP).

Output: Diagnostic images sent via DICOM to PACS/workstations. Benefits: Improved lung nodule detectability; reduced metal artifacts; flexible patient positioning (sitting, standing, supine). Helix workstation allows standalone processing of acquired images.

Clinical Evidence

Bench testing only. No clinical studies required. Verification and validation included risk analysis, module/system integration testing, and simulated use testing. Metal Artifact Reduction algorithm performance validated using anthropomorphic phantoms to confirm reduction of ripple and ghost artifacts.

The list of detectors verified and validated for use with the Discovery XR656 HD system, including their specifications, are provided in the user documentation. The System generates diagnostic radiographic images which can be sent through a DICOM network for applications including printing, viewing, and storage. The components may be combined in different configurations to meet specific customer needs. In addition, upgrade configurations are available for predicate devices. The optional image pasting function enables the operator to stitch sequentially acquired radiographs into a single image. This 510(k) is to incorporate the VolumeRad advanced application that was currently available on the Discovery XR656 product onto the Discovery XR656 HD, as well as introduce a new Metal Artifact Reduction Algorithm, and an optional standalone console to take any Helix™ acquired images via DICOM (such as from a Discovery XR656 HD, Optima XR646 HD, or Optima XR240amx) and process the images independently of the system it was acquired on. | | Intended Use: | General Purpose Digital Radiographic Imaging System | | Indications for Use: | The Discovery XR656 HD is intended to generate digital radiographic images of the skull, spinal column, chest, abdomen, extremities, and other body parts in patients of all ages. Applications can be performed with the patient sitting, standing, or lying in the prone or supine position and the system is intended for use in all routine radiography exams. Optional image pasting function enables the operator to stitch sequentially acquired radiographs into a single image. The Discovery XR656 HD incorporates AutoGrid, which is an optional image processing software installed as a part of the systems Helix image processing software. AutoGrid can be used in lieu of an anti-scatter grid to improve image contrast in general radiographic images by reducing the effects of scatter radiation. When the VolumeRAD option is included on the system, the system can generate tomographic images of human anatomy including the skull, spinal column, chest, abdomen, extremities, and other body parts in patients of all ages. When the VolumeRAD option is used for patients undergoing thoracic imaging, it is indicated for the detection of lung nodules. VolumeRad generates diagnostic images of the chest that aid the radiologist in achieving superior detectability of | | lung nodules versus posterior-anterior and left lateral views of the chest, at a comparable radiation level. | | | The device is not intended for mammographic applications. | | | Technology: | The Discovery XR656 HD with VolumeRad employs the same fundamental scientific technology and software as its predicate devices. The intended use and patient populations are the same between Discovery XR656 HD with VolumeRad and the predicate devices. The indication for use has been updated to include the VolumeRad indications cleared under K132261, as well as the AutoGrid indications cleared under reference device Optima XR240amx with AutoGrid (K173602). The incorporation of the AutoGrid feature is due to the Optima XR240amx and the Discovery XR656 HD both incorporating the Helix™ image processing software, and AutoGrid is embedded within this software. The AutoGrid option is only available for Digital Cassette exposures (when the detector is not docked in the table or wallstand), and when a physical grid is required per the protocol database, but not detected as present. AutoGrid is not intended to be applied when a physical grid has been used to acquire an image. The Discovery XR656 HD with VolumeRad did not change the system software architecture, operator I/F, Tube, or generator. It does incorporate the same 6-axis Overhead Tube Suspension (OTS) and Overhead Bridge that enables the automatic positioning feature and image pasting technique. | | | The differences being introduced are: | | | 1. The incorporation of the VolumeRad feature previously available with the Discovery XR656 (K132261) into the Discovery XR656 HD product | | | 2. An additional Metal Artifact Reduction algorithm for VolumeRad. | | | 3. Helix™ Workstation. | | | The VolumeRad feature allows digital tomographic images of the human body in patients either lying down or standing. Volume RAD involves a series of up to 60 very low dose projection images during a single sweep of the overhead tube assembly (OTS) with the detectors physically docked in the table or wallstand and the tube moving within a limited angular range (up to 40 degrees). The system automatically adjusts collimation throughout the sweep to maintain radiation in the imaging area selected during exam setup. After a VolumeRad acquisition, the system uses a filtered back projection (FBP) technique to reconstruct slices down to a minimum thickness of 1mm parallel to the receptor. The VolumeRad OTS sweep and image reconstruction algorithms are identical between the predicate and proposed products. The difference introduced was in the image acquisition due to the detector resolution change between the Discovery XR656 and the Discovery XR656 HD products. Also, the Discovery XR656 HD with VolumeRad provides an optional Metal Artifact Reduction algorithm to reduce the ripple and ghost artifacts created when metal is present within the anatomy where the images are acquired. | | | The Helix™ Workstation incorporates the PC, Monitor, and software of the Discovery XR656 HD and can be used as a standalone console to take any Helix™ acquired images via DICOM (such as from a Discovery XR656 HD, Optima XR646 | | | HD, or Optima XR240amx) and process the images independently of the system it | | | was acquired on. The images can then be sent via DICOM to a PACS or other | | | image review station. | | Determination of Substantial Equivalence: | Summary of Non-Clinical Tests: The Discovery XR656 HD and its applications comply with voluntary standards: | | | • ES60601-1 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance; | | | • IEC 60601-1-2 Medical Electrical Equipment - Part 1-2: General Requirements for Basic Safety and Essential Performance – Collateral Standard: Electromagnetic Compatibility - Requirements and Tests; | | | • IEC 60601-1-3 Medical Elec.
