It will allow for high resolution images of the thorax, abdomen, pelvis, and spine. ## Device Story Gore 3.0T Torso Array is a receive-only phased array MRI surface coil; consists of anterior and posterior paddles; 4-element flexible design conforms to various body sizes. Used with GE Signa 3.0T MR systems to acquire high-resolution images of thorax, abdomen, pelvis, and spine. Operates as receiving coil; utilizes active and passive decoupling; includes MR-safe cable. Used in clinical imaging environments; operated by trained MRI technologists/radiologists. Output is raw MR signal data processed by the host MR system into diagnostic images for clinical interpretation. Benefits include improved image resolution for anatomical assessment. ## Clinical Evidence Bench testing only. Substantial equivalence demonstrated by imaging various anatomical locations and comparing clinical images to those produced by predicate devices. ## Technological Characteristics Receive-only phased array coil; 4-element flexible design; biocompatible closed-cell polyethylene foam patient contact areas. Features active and passive decoupling; MR-safe cable. Compatible with GE Signa 3.0T MR systems. ## Regulatory Identification A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information). ## Special Controls *Classification.* Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9. ## Predicate Devices - GE 3.0T Transmit/Receive Body Imaging Coil ([K003613](/device/K003613.md)) - GE 1.5T Torso Array ([K911806](/device/K911806.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Premarket Notification 510(k) Summary NOV 1 8 2002 - a. Submitter: W. L. Gore and Associates, Inc. 750 Ott's Chapel Road Newark, DE 19713 Telephone: 800-441-7404 Tracy Wolf Contact: Date Prepared: October 4, 2002 - b. Name of Device: Trade Name: Gore 3.0T Torso Array Common Name: MRI Surface Coil Device Name: Coil, Magnetic Resonance, Specialty - c. Identification of Predicate Devices: The GE 3.0T Transmit/Receive Body Imaging Coil (K003613) and the GE 1.5T Torso Array (K911806) are the predicate devices. which were found to be substantially equivalent through the premarket notification process. The GE 3.0T Transmit/Receive Body Imaging Coil represents a coil that is compatible with a 3 Tesla field strength MR system, capable of imaging the neck, spine, abdomen, thorax, and extremities. The body coil is built into the GE 3.0T Signa® Magnetic Resonance system, as part of the patient couch. The GE 1.5T Torso Array represents a 4 loop phased array designed for use with GE Signa® 1.5T MR Systems, to image the thorax, abdomen, pelvis, and spine. - d. Description of the Applicant Device: The Gore 3.0T Torso Array is a receive only phased array coil, consisting of an anterior and a posterior "paddle." The phased array design includes 4 elements in a flexible coil, which conforms to different body sizes. The coil produces high resolution images with GE Signa® 3.0T MR Systems. {1}------------------------------------------------ - e. Intended Use: The Gore 3.0T Torso Array is intended for multiple imaging applications with GE Signa® 3.0T MR Systems. It will allow for high resolution images of the thorax, abdomen, pelvis, and spine. - f. Technical Characteristics The Gore 3.0T Torso Array is substantially equivalent to the predicate devices with regard to intended use. This has been demonstrated by imaging a variety of anatomical locations and comparing the clinical images. The descriptive information and performance data contained within this Premarket Notification submission are sufficient to demonstrate substantial equivalence of the Gore 3.0T Torso Array (applicant device) to the GE 3.0T Transmit/Receive Body Imaging Coil and GE 1.5T Torso Array (predicate devices). The Gore 3.0T Torso Array uses the same mode of operation, a receiving coil, as the predicate devices can employ. The GE 3.0T Transmit/Receive Body Imaging Coil can also operate as a transmitting coil. The Gore 3.0T Torso Array utilizes active decoupling as do the predicate devices. The Gore 3.0T Torso Array further enhances patient safety by including passive decoupling, and the MR safe cable. The materials of the Gore 3.0T Torso Array (applicant) are similar to those used in the GE 1.5T Torso Array (predicate). The patient contact areas for both coils are composed of a biocompatible closed cell polyethylene foam. In summary, the Gore 3.0T Torso Array (applicant) utilizes similar technology and materials as does the GE 3.0T Transmit/Receive Body Imaging Coil (predicate) and the GE 1.5T Torso Array and is, therefore, substantially equivalent to these devices. There are no patient safety concerns raised as a result of the clearance of the Gore 3.0T Torso Array. {2}------------------------------------------------ Image /page/2/Picture/2 description: The image shows the address of the Food and Drug Administration.
