The summary describes a portable gamma camera with a solid-state detector and mentions standard performance testing (electrical safety, EMC, NEMA, clinical images). There is no mention of AI, ML, image processing beyond basic detection, or any data sets for training or testing algorithms.
No
The device is a gamma camera used for imaging and diagnostic purposes, not for treating diseases or improving health outcomes.
Yes
The device is indicated for use to image the distribution of radionuclides in the human body, providing information that can be used for diagnosis.
No
The device description explicitly details hardware components like a solid-state detector, CZT crystals, and a computer (desktop or laptop), indicating it is a hardware device with associated software.
Based on the provided information, the Anzai eZ-Scope AN Portable Gamma Camera is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "image the distribution of radionuclides in the human body using planar imaging techniques." This describes an in vivo (within the living body) diagnostic imaging procedure, not an in vitro (outside the living body) test performed on biological samples.
- Device Description: The description focuses on the technology used to detect gamma rays from within the body.
- Anatomical Site: The indicated anatomical site is the "Human body," further supporting its in vivo use.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or performing tests on these samples outside the body.
While the device can be used on pathological specimens, this is a secondary use and requires a protective sheath, suggesting it's not its primary intended purpose as an IVD. The core function is imaging radionuclides within the human body.

Device Description
The Anzai eZ-Scope AN Portable Gamma Camera is a new and innovative portable gamma camera. The camera utilizes a solid state detector, rather than a scintilator, to detect gamma rays. The cadmium-zinc-tellurium detector allows sharp energy discrimination and spatial resolution. The detector array is made from pixelized cadmium-zinc-telluride (CZT) crystals, with each of the 256 pixels having dimensions of 2 x 2 mm. The system will be available in two configurations, eZ-Scope AN and eZ-Scope Life. These differ primarily in the computer, the former model using a desktop computer and the latter a laptop. In the desktop version, the computer is mounted on a cart, while the laptop version does not have a cart.

510(k) Summary
Anzai eZ-Scope AN Portable Gamma Camera
Common/Classification Name: Gamma Camera, 21 CFR 892.1100
Anzai Medical Company, Ltd. 3-6-25 Nishi-Shinagawa Shinagawa-ku Tokyo 141-0033 Japan
Contact: Masao Jimbo, Prepared: May 10, 2002
LEGALLY MARKETED PREDICATE DEVICES A.
The eZ-Scope AN Portable Gamma Camera is substantially equivalent to the Notebook Imager made by Digirad, which was cleared by FDA on May 28, 1997 as K961004. For some characteristics, it is also substantially equivalent to the Siemens E.CAM gamma camera (K992731) and the Neoprobe 2000 Isotope Probe (based on K971320 for the Neo 1500).
B. DEVICE DESCRIPTION
The Anzai eZ-Scope AN Portable Gamma Camera is a new and innovative portable gamma camera. The camera utilizes a solid state detector, rather than a scintilator, to detect gamma rays. The cadmium-zinc-tellurium detector allows sharp energy discrimination and spatial resolution.
The detector array is made from pixelized cadmium-zinc-telluride (CZT) crystals, with each of the 256 pixels having dimensions of 2 x 2 mm.
The system will be available in two configurations, eZ-Scope AN and eZ-Scope Life. These differ primarily in the computer, the former model using a desktop computer and the latter a laptop. In the desktop version, the computer is mounted on a cart, while the laptop version does not have a cart.
். INTENDED USE
The Anzai eZ-Scope AN Portable Gamma Camera is indicated for use to image the distribution of radionuclides in the human body using planar imaging techniques. The eZ-Scope may be used on pathological specimens if a protective sheath is used.

SUBSTANTIAL EQUIVALENCE SUMMARY D.
The eZ-Scope is a medical device, and it has similar indications for use and target population as the legally marketed predicate devices. However, the differences in indications for use do not affect the intended The eZ-Scope has the same technological diagnostic effect. characteristics as the predicate devices. For most characteristics, this premarket notification will describe the characteristics of the eZ-Scope in sufficient detail to assure substantial equivalence.1 For a few characteristics, performance data are provided to assure equivalence.
TECHNOLOGICAL CHARACTERISTICS E.
The technological characteristics are the same as those of the predicate devices.
E. TESTING
Performance testing addressed the following issues:
- Electrical Safety; (1)
- Electromagnetic Compatibility; (2)
- NEMA Performance Standard; and (3)
- Sample Clinical Images (4)
CONCLUSIONS G.
This pre-market notification has demonstrated Substantial Equivalence as defined and understood in Sections 513(f)(1) and 513(i)(1) of the Federal Food Drug and Cosmetic Act and various guidance documents issued by the Center for Devices and Radiological Health.
し The meaning of the terms "substantial equivalence" and "substantially equivalent" as used in this 510(K) is limited to the way they are defined in, and used by FDA in accordance with, Sections 513(f)(1) and 513(i)(1) of the Federal Food, Drug, and Cosmetic Act.

Dear Dr. Athey:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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 (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.
