The MJAH-167A is intended to be used on a Toshiba 1.5T MR System ## Device Story Octave SPEEDER Head is a receive-only phased array coil for 1.5T MRI systems; captures NMR signals from head, cervical region, and upper chest. Device comprises a head base (7 elements) and removable anterior coil (4 elements). Operates by switching between transmit and receive modes via PIN diodes; detuned during transmission by whole-body coil and tuned during reception. Used in clinical imaging environments by trained MRI technologists/radiologists. Output consists of raw NMR signals processed by the host MRI system into diagnostic images. Benefits include high-resolution imaging of specified anatomical regions for clinical diagnosis. ## Clinical Evidence Bench testing only. Performance verified using phantoms and imaging quality metrics. No clinical data presented. ## Technological Characteristics Receive-only phased array coil; 8-channel configuration. Materials: biocompatible. Sensing: PIN diode-based switching for transmit/receive tuning. Energy: RF magnetic resonance. Connectivity: Connects to Toshiba 1.5T MR System. Standards: IEC60601-1, IEC60601-2, IEC60601-1-6, IEC62366, IEC60601-2-33. ## 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 - Atlas SPEEDER Head/Cervical coil ([K083014](/device/K083014.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Device Description The Octave SPEEDER Head is a receive-only phased Array Coil that can receive NMR signal from head, cervical region and upper chest. The coil consists two parts of a head base, a removable anterior coil. The head base includes 7 coil elements, which are divided into 3 sections. The removable anterior coil includes 4 coil elements, which are divided into 2 sections: Users select the sections according to region of interest via a system user interface. The PC board switches transmit mode and receive mode with PIN diode. This coil is detuned during transmission by our QD whole body coil by means of activating the PIN diodes (transmit mode) and tuned during no transmission by means of not activating the PIN diodes (receive mode). #### 8. Indication for Use The Octave SPEEDER Head is intended for imaging of the brain, cervical spine, and soft tissue and vasculature of the head, neck and upper chest. The MJAH-167A is intended to be used on a Toshiba 1.5T MR System #### Design Change 9. The SPEEDER technology has been previously cleared under K083014 as an Atlas SPEEDER Head/Cervical coil. The primary difference is the creation of an 8ch SPEEDER Head. The new Octave (8ch) SPEEDER Head will use the same SPEEDER technology as other cleared SPEEDER devices. #### 10.
