Owandy-RX

Introduction:

Your intraoral Owandy-RX is a new generation generator designed exclusively for intraoral X-rays. With its user-friendly design and interface, the Owandy-RX offers you quality and shot repetition, whilst combining a small focal spot with reduced exposure times.

The Owandy-RX produces high quality X-rays due to the repetitiveness of its electronic settings and exposure times, together with a minimal electronic focal spot. It is also compatible with digital image acquisition equipment. If you do not have this type of digital system, we recommend that you use high speed films in order to limit the dose of X-rays absorbed by the patient.
This operational mode can be selected using the timer keypad: it is also possible to choose between two films at different speeds (sensitivities), a digital sensor or a table of exposure times that is completely customisable by the user.

The Owandy-RX comprises a generator, an X-ray tube head complete with collimator, an electronic CPU card which controls the equipment functions, a keypad for adjusting the settings and an X-ray starter – in standard configuration, the keypad is directly relayed to the CPU card. With the remote timer option, the keypad acts as a remote control and the X-ray starter is substituted by a replacement button located directly on the keypad itself.

The Owandy-RX generator is the HF (high frequency) or DC (direct current) type, which allows the dose of X-rays received by the patient to be reduced (in comparison with the old AC (alternating current) type generators), due to the generation of the quasi-continuous voltage with a stable and constant production of X-rays. The production of so-called “soft” X-rays (to be avoided as they cannot be used for the generation of a radiograph) is also greatly reduced due to this high voltage current, given that “soft” X-rays are produced at low voltages.
