Device functions as physical radiation filter, allowing high-energy photons from positron-emitting tracers to reach detector crystals while blocking scattered radiation. Used in clinical nuclear medicine departments by trained technologists/physicians. Output consists of raw projection data processed by the host gamma camera system to generate tomographic images. Enables visualization of radiopharmaceutical distribution for diagnostic assessment. Benefits include improved high-energy imaging capability for positron-emitting isotopes compared to standard collimators. ## Clinical Evidence Bench testing only. Performance evaluated against NEMA NU 1-1994 standards for scintillation cameras. Comparison provided for resolution (FWHM) at surface and 10 cm distance using 18F and 99mTc sources. ## Technological Characteristics Ultra High Energy Collimator; 7,500 hexagonal holes; 76 mm thickness; 4 mm hole size; 2 mm septa thickness; 419 mm x 566 mm rectangular field size. Energy range 50-562 KeV. Performance measured per NEMA NU 1-1994. Safety standards: CAN/CSA-C22.2 No 114-M90, IEC 601-1, UL544. ## 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 - Dyna camera 2 series high energy collimators ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

DEVICE NAME Device Name: 511 KeV Collimator Proprietary Name: ISOCAM I (Single Head Gamma Camera) ISOCAM II (Dual Head Gamma Camera) Classification Name: System, Tomography, Computed, Emission {2} 510(k) Premarket Notification Summary # 3. INTRODUCTION We manufacture single and dual detector gamma cameras, hereafter, called ISOCAM I and ISOCAM II respectively, which recently underwent FDA review. At the request of the FDA, this 510(K) is being submitted specifically for the 511 KeV collimator option for the Park Medical Systems ISOCAM I and ISOCAM II nuclear imaging systems. The format for this submission follows the FDA document entitled, “Premarket Notification 510(k) Regulatory Requirements for Medical Devices”. In addition to the information in our previous 510(k) which included high energy imaging with 511 KeV collimators, the information requested in the recent FDA letter to industry concerning 511 KeV collimators, has also been included in this submission. This submission shows substantial equivalence of Park 511 KeV collimators to the pre-ammendment high energy collimators used with the Dyna camera. {3} 510(k) Premarket Notification Summary # 4.
