No
The document explicitly states that "standard image processing algorithms are used" and there is no mention of AI, ML, or related terms.
No
The device is used for imaging and detecting radionuclides to visualize their distribution, which identifies it as a diagnostic tool, not a therapeutic one.
Yes
The device is described as a "nuclear medical imager," used for "imaging the distribution of radionuclides in the human body," and "extracorporeally detects and visualizes the gamma ray emitted from an administered radiopharmaceutical." This imaging and visualization process is inherently diagnostic, as it provides information about the internal state or condition of the body.
No
The device description clearly states it is a nuclear medical imager (gamma camera) that incorporates solid-state CdTe semiconductor detectors, indicating it is a hardware device that also utilizes software for image processing.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The intended use and device description clearly state that this device is used for "imaging the distribution of radionuclides in the human body" and "extracorporeally detects and visualizes the gamma ray emitted from an administered radiopharmaceutical." This involves imaging within the body, not analyzing samples from the body.
- The device is a medical imager. It's described as a "nuclear medical imager" and a "scintillation or gamma camera." These are imaging devices used to visualize processes within the body, not diagnostic tests performed on samples.
Therefore, the Mini Gamma Camera MGC500-101U and MGC500-301U fall under the category of medical imaging devices, not In Vitro Diagnostics.

Device Description
The Mini Gamma Camera MGC500-101U and MGC500-301U , are nuclear medical imagers (commonly known as a scintillation or gamma camera) that are smaller, lighter and more portable than most existing gamma cameras. The MGC500-101U and MGC500-301U are intended for use in nuclear medicine procedures, including intraoperative procedures. To collect such information, it extracorporeally detects and visualizes the gamma ray emitted from an administered radiopharmaceutical. While previous gamma cameras have consisted of a sodium iodide scintillating crystal and photomultiplier tube (PMT), the design of the MGC500-101U and MGC500-301U incorporate solid-state CdTe semiconductor detectors. This allows the device to be smaller, lighter, and more portable.
Both of the modified models have a new high-uniformity mode and the Model MGC500-301U has been reconfigured into a more compact design.

LEGALLY MARKETED PREDICATE DEVICE A.
The Mini Gamma Camera Models MGC500-101U and MGC500-301U are substantially equivalent to the currently marketed MGC500 (K040587).
B. DEVICE DESCRIPTION
The Mini Gamma Camera MGC500-101U and MGC500-301U , are nuclear medical imagers (commonly known as a scintillation or gamma camera) that are smaller, lighter and more portable than most existing gamma cameras. The MGC500-101U and MGC500-301U are intended for use in nuclear medicine procedures, including intraoperative procedures. To collect such information, it extracorporeally detects and visualizes the gamma ray emitted from an administered radiopharmaceutical. While previous gamma cameras have consisted of a sodium iodide scintillating crystal and photomultiplier tube (PMT), the design of the MGC500-101U and MGC500-301U incorporate solid-state CdTe semiconductor detectors. This allows the device to be smaller, lighter, and more portable.
Both of the modified models have a new high-uniformity mode and the Model MGC500-301U has been reconfigured into a more compact design.
C. INTENDED USE
The Mini Gamma Camera MGC500-101U and MGC500-301U are indicated for use in imaging the distribution of radionuclides in the human body using planer imaging techniques. The MGC500-101U and MGC500

301U may also be used intraoperatively if a protective sheath is used.
SUBSTANTIAL EQUIVALENCE SUMMARY D.
The MGC-500-101U and MGC500-301U are medical devices, and they have the same indications for use and target population as the legally marketed predicate device. The MGC-500-101U and MGC500-301U have the same technological characteristics as the predicate device. Many of the characteristics of the device are sufficiently precise that performance data are not required, but for others, performance data were collected. The verification/validation activities carried out under Acrorad's procedures for medical device development and modification ensure that the new versions of the device are substantially equivalent to the currently marketed version of the device.
TECHNOLOGICAL CHARACTERISTICS ய்
The proposed and predicate devices both use a detector head with CdTe detectors that convert photon energy into electrical signals. The electrical signals generated by the incoming gamma photons are proportional to energy of the photons. Discriminators are used in hardware or software in both proposed and predicate devices to limit acceptable detection events to the gamma energy of the radiopharmaceutical being used for imaging. The location of a gamma detection event is determined by the location of the channel of the detector, and standard image processing algorithms are used to present the image to the user. These technological characteristics are unchanged from the original version of the device.
TESTING ட்
The Mini Gamma Camera MGC500-101U and MGC500-301U were tested to the specifications of the NEMA Performance Standard for scintillation cameras. It was also tested to the requirements of the IEC-60601-1 for electrical safety.
CONCLUSIONS G.
This pre-market notification has demonstrated Substantial Equivalence as 1110 pro marked 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.
The meaning of the terms "substantial equivalence" and "substantially equivalent" as used in 1 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(l)(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 (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 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.
