Radiological apparatus particularly for veterinary use (skanray europe s.r.l.) r gasquet tennis

As is known, the radiological apparatuses currently used to obtain radiological images of human or animal patients comprise, generally, the following components: an X-ray generator, with related power electronics to power it (i.e. a converter); a collimator for X-rays, with an illuminated device for centering the irradiated field; an electronic system for controlling the emission of X-rays; a radiolucent table for supporting the patient; mechanical structural elements, such as in particular the stand, for supporting and positioning the radiographic generator; and a radiographic detector and/or systems for accommodating/positioning it below the radiolucent table.

In conventional apparatuses, there may also be further subsystems and optional accessories, such as, for example, a radiographic grid with a Potter-Bucky device associated with it and, for apparatuses with a digital detector, optionally also the radiographic imaging software and patient records software.

In the simpler apparatuses of this type, such as, for example, the cheaper ones for veterinary radiology on small and medium-sized pets, the radiolucent table is typically constituted by a fixed support on which the animal patient is positioned and, as needed, moved by the operator, in order to make the irradiated field correspond to the anatomical area of interest.

In the vast majority of cases, however, and practically always in radiology on adult humans, the radiolucent table is floating i.e. it is installed on a lower base structure so as to be moveable, with respect to the base structure proper, along an axis parallel to its longitudinal extension and, often, also along an axis parallel to its transverse extension, so that the area to be radiographed can be located precisely in the irradiated field, which in turn is located at the underlying image detector.

This is not very important for hospital radiology rooms, which are generally quite large, but it becomes a problem in small clinics, especially veterinary clinics, which are often housed in residential buildings where space is often limited.

Another disadvantageous aspect of radiological apparatuses with a bucky table, especially in veterinary applications, arises from the fact that generally the actual radiographic emission is preceded by a step of preparation. Such step of preparation can imply, among other things, actuating or achieving rotation speed in generators that use a rotating anode X-ray tube, reaching the temperature for thermionic emission by the filament of the X-ray tube, readying electronic devices, such as for example flushing dark charges in image detectors, as well as operations to ready the software, for example for the data transmission of the digital image.

The step of preparation can require several seconds, during which time the patient should remain still without moving even slightly from the position in which it has been arranged. Typically, the sequence of steps of preparation and of subsequent emission of X-rays is generally commanded by a two-stage manual button. In particular, actuation of the first stage of the button begins the step of preparation, the completion of which is indicated by way of an acoustic and/or luminous signal, while the actual emission is then triggered by actuating the second stage of the button.

The step of preparation is particularly disadvantageous in veterinary radiology, since the animal patient will not be cooperating and the operator therefore needs the X-ray emission to happen immediately after actuating the emission command, which is carried out by the operator when the operator considers that the animal is ready and before the animal might start moving. Among other things, the step of preparation may imply stimuli, such as for example the buzzing of the anode accelerating in rotation, which disturb the animal and cause it to move. SUMMARY

Within this aim, the disclosure provides a radiological apparatus particularly for veterinary use that makes it possible to keep the patient animal in a fixed position without needing to have to move it in order to position the area to be radiographed under the irradiated field.

The disclosure further provides a radiological apparatus particularly for veterinary use that, in addition to offering the widest guarantees of reliability and safety during its operation, is structurally simple, so as to be easy to make and also highly competitive from a purely economic viewpoint.

These advantages and features which will become better apparent hereinafter are achieved by providing a radiological apparatus particularly for veterinary use according to claim 1, optionally provided with one or more of the characteristics of the dependent claims.
