Planar imaging, Whole body imaging, Tomographic imaging (SPECT) for non Positron emitter, Positron imaging without coincidence. Could be used with 511 keV photon imaging and photons of smaller energy simultaneously (e.g. 140 keV and 511 keV). ## Device Story 511 keV collimator designed for TRIONIX Triad nuclear medicine systems; enables imaging of radionuclides emitting 511 keV photons. Device functions as physical component for gamma camera; restricts photon path to allow spatial localization of radiation source. Used in clinical nuclear medicine departments; operated by trained technologists/physicians. Output consists of raw radiation detection data processed by host system into diagnostic images. Facilitates visualization of radionuclide distribution; aids clinical decision-making regarding patient pathology. Benefits include expanded imaging capabilities for high-energy isotopes on existing SPECT platforms. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics High-energy collimator designed for 511 keV photon imaging. Mechanical component for gamma camera systems. Compatible with simultaneous multi-isotope imaging (e.g., 140 keV and 511 keV). ## Regulatory Identification An emission computed tomography system is a device intended to detect the location and distribution of gamma ray- and positron-emitting radionuclides in the body and produce cross-sectional images through computer reconstruction of the data. This generic type of device may include signal analysis and display equipment, patient and equipment supports, radionuclide anatomical markers, component parts, and accessories. ## Predicate Devices - T88 ([K873775](/device/K873775.md)/A) - Cardiac Triad (9" and 20") ([K920776](/device/K920776.md)) - Cardiac Triad (9" and 20") ([K923345](/device/K923345.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4591 for Radiology devices, or 594-4613 for Ear, Nose and Throat devices. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address "http://www.fda.gov/cdrh/dsmamain.html".
