TROPHY Minorex Mobile Dental X-Ray Unit Analysis Report

Device Detection and Identification

The product examined in the visuals is a dental X-ray unit with a mobile (wheeled) stand system. The product is an integrated system consisting of the main head (tube) used for radiographic imaging, movable articulated arms (acrobatic arm), a control unit, and a base.

Brand and Model Information

As a result of a detailed examination of the technical label on the product in the visuals, the following information has been identified:

• Brand: TROPHY (Trophy Radiologie, Vincennes, France-based manufacturer)
• Model: MINOREX
• Tube Manufacturer: It is stated that the X-ray tube in the internal mechanism is manufactured by the “TOSHIBA” brand.
• Place of Manufacture: MADE IN FRANCE (French production)

Originality Status

Upon examining the metal label plate on the device, its riveted structure, period-specific fonts, and approval codes (Homologation), the product is assessed to be completely original.

Areas of Use

This device is designed for intraoral radiography in the field of dentistry (odontology). It is used for imaging teeth, roots, and jaw structure. Thanks to its mobile design, it can be moved to different rooms within the clinic.

Label and Technical Data

The technical data read from the metal label on the device’s head (tube unit) are as follows:

• Serial Number: 97662
• Device Type: MINOREX
• Voltage Value (H.T.K.V): 50 kV (50 Kilovolt)
• Focal Spot: 1×1 mm
• Filtration (Pref.): 2 Al (2 mm Aluminum equivalent filtration)
• Approval/Homologation: N° 667.ES.64
• Tube Type: E. 7509
• Relevant Legislation Date: The label states “Arrêté du 29.1.64” (Decree of the Ministry of Public Health dated January 29, 1964).

General Condition and State

The product, by its general appearance, is old enough to be classified as antique or vintage. The condition analysis based on visual inspection is as follows:

• Cosmetic Condition: Wear and tear due to years of use are observed on the metal and plastic parts of the device. There are yellowing spots on the white/cream-colored paint.
• Metal Surfaces: Rusting (oxidation) has started on the large connecting screw on the label and at various metal joints.
• Cleanliness: Dust accumulation is present between the coiled cables and on the surfaces of the product, giving the impression that it has been stored for a long time.

Physical Deformation and Mechanical Components

No major cracks that would break the integrity of the device’s skeletal structure are observed. The connections of the articulated arms are in place, but it cannot be visually tested whether the mechanisms operate smoothly. In the cable structure, particularly in the coiled cable, age-related deformities and loosening (stretching) are noticeable.

Electronic Components and Battery Status

The device operates on mains electricity (it is not battery-powered). Black electrical cables emerging from the main body are visible in the visuals. The power cable or plug end of the device cannot be clearly distinguished in the visuals.

Accessories

In the visual, there is a gray rectangular control box positioned on the main arm of the device. Connected to this box, there is a handheld switch/trigger mechanism with a coiled cable, likely used for remote exposure (shooting).

Quantity Information

The visuals show 1 (one) unit of a Trophy Minorex brand mobile dental X-ray unit and its integrated components.

Estimated Year of Manufacture

The legal regulation date referenced on the label is 1964. Considering this reference and the device’s design language (mechanical counters, analog structure, font usage), the product is estimated to have been manufactured in the late 1960s or early 1970s.

Potential Malfunction Risk and Safety Warning

Given the device’s year of manufacture and its current physical condition, there is a high probability that electrical insulation materials have lost their properties over time. There is a risk of cables drying out or cracking. Furthermore, in such old X-ray devices, risks of calibration errors or radiation leakage are technical issues that cannot be detected by visual inspection but should not be overlooked. It is essential that the device is inspected by a specialist biomedical technician before being plugged in.
