Intended Use
The Hitachi CB MercuRay system is an x-ray imaging device that uses a cone beam with a 360°rotational sequence, providing two-dimensional images and three-dimensional volume reconstructions. The system specifically images the head and neck areas, which includes ENT and dentomaxillofacial areas, for use in planning and diagnostic support.
Device Description
The CB MercuRay system is an x-ray device that uses a cone beam with a 360°rotational sequence, providing twodimensional images and three-dimensional volume reconstructions for ENT and dentomaxillofacial applications. The system consists of two main components; scanner and console. The scanner contains a U-arm with an x-ray generator with a 9" or 12" Image Intensifier and a 100M pixel CCD camera horizontally facing each other. The Uarm rotates horizontally around the patient's head. Data acquisition is performed with the patient in an upright, seated position. Images can be printed or exported on standard computer media.
More Information

Not Found

No
The summary describes standard image processing techniques (offset correction, logarithmic conversion, sensitivity correction, geometric distortion correction) and 3D reconstruction, but does not mention any AI or ML algorithms.

No
The device is described as an x-ray imaging system for planning and diagnostic support, not for treating conditions.

Yes

The device description states its use is "for use in planning and diagnostic support", which indicates its role in diagnosis.

No

The device description clearly states the system consists of a scanner and a console, with the scanner containing hardware components like an x-ray generator, image intensifier, and CCD camera. This indicates it is a hardware device with integrated software, not a software-only medical device.

Based on the provided information, the Hitachi CB MercuRay system is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Hitachi CB MercuRay system is an x-ray imaging device. It directly images the human body (head and neck) using radiation. It does not analyze samples taken from the body.
  • Intended Use: The intended use is for "planning and diagnostic support" based on the generated images, not on the analysis of biological samples.

Therefore, the Hitachi CB MercuRay system falls under the category of medical imaging devices, not In Vitro Diagnostics.

Device Description

The CB MercuRay system is an x-ray device that uses a cone beam with a 360°rotational sequence, providing twodimensional images and three-dimensional volume reconstructions for ENT and dentomaxillofacial applications.

The CB MercuRay system incorporates conebeam technology. The x-rays are continuously emitted in a cone shape during rotation providing image data of 288 views. Projection images acquired are applied with offset correction and logarithmic conversion. The data are then applied with corrections for detector sensitivity, geometric distortion and runover of the subject. The acquired data can be presented as 2-dimensional images or can be reconstructed as a 3dimensional 5123 matrix image.

The system consists of two main components; scanner and console. The scanner contains a U-arm with an x-ray generator with a 9" or 12" Image Intensifier and a 100M pixel CCD camera horizontally facing each other.

Device Description

Function

The CB MercuRay system is an x-ray device that uses a cone beam with a 360°rotational sequence, providing twodimensional images and three-dimensional volume reconstructions for ENT and dentomaxillofacial applications.

Scientific Concepts

The CB MercuRay system incorporates conebeam technology. The x-rays are continuously emitted in a cone shape during rotation providing image data of 288 views. Projection images acquired are applied with offset correction and logarithmic conversion. The data are then applied with corrections for detector sensitivity, geometric distortion and runover of the subject. The acquired data can be presented as 2-dimensional images or can be reconstructed as a 3dimensional 5123 matrix image.

Physical and Performance Characteristics

The system consists of two main components; scanner and console. The scanner contains a U-arm with an x-ray generator with a 9" or 12" Image Intensifier and a 100M pixel CCD camera horizontally facing each other. The Uarm rotates horizontally around the patient's head. Data acquisition is performed with the patient in an upright, seated position. Images can be printed or exported on standard computer media.

Device Intended Use

The CB MercuRay system is an x-ray imaging device that provides two-dimensional images and three-dimensional volume reconstructions. The system specifically images the head and neck areas, which includes ENT and dentomaxillofacial areas, for use in planning and diagnostic support.

Device Technological Characteristics

The CB MercuRay system acquires data in the same manner as the predicate device. Physically, the significant difference is that the CB MercuRay positions the patient in an upright, seated position during acquisition. The predicate device acquires data with the patient lying down on a table. The remaining differences are increased options and features with the CB MercuRay such as four different fields of view and increased 3D features within the viewing software.

Despite these small differences, the CB MercuRay system is technologically equivalent in concept, function, and performance to the predicate device.

Conclusions

The CB MercuRay system has been developed and validated according to applicable standards. Testing has proven that the CB MercuRay system is safe and effective for the indicated use. Risk and hazard analysis shows that there are no new safety issues associated with this system as compared with the predicate device.

Dear Mr. Sherratt:

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.
