Description

This invention relates to an improved radiographic imaging device of the kind defined in the preamble of claim 1. In particular, the invention relates to a device configured for use in the medical/veterinary field to acquire at least radiographic images (such as tomography) of at least a portion of a patient's internal anatomical structures. Regardless of the analysis performed (tomography, radiography, or fluoroscopy), known radiographic imaging devices share the same basic structure. This basic structure includes a platform on which the patient is positioned, a control station for the device, an O- or C-shaped gantry defining the space into which the part to be analyzed and which performs radiographic acquisition is inserted, and supports that support the gantry and platform, allowing the platform and gantry to move in translation between them. The gantry contains the X-ray source; and detectors that receive the X-rays after they have passed through the platform and the patient. Radiation devices for CAT (Computed Axial Tomography) or CT (Computed Tomography) have a rotating mechanism that rotates the source and detector around the patient, allowing the device to acquire images at various angles and thus generate a three-dimensional reconstruction of the patient. Examples of such devices are reported in US2004125915A1, WO2014001834, and US20030072416. The known technologies described contain several significant drawbacks. In particular, known radiographic imaging devices are especially bulky, thus reducing their portability. Another drawback is that aiming is slow and inaccurate with currently used radiographic imaging devices. In fact, aiming is performed manually by the operator, who must use a camera near the source to understand when the source is centered with respect to the part being analyzed. A significant drawback is also represented by the fact that known radiographic imaging devices only enable a limited range of acquisitions, as multiple machines specific to each type of radiographic imaging must be purchased. Another drawback is represented by the fact that known radiographic imaging devices consist of numerous complex components, which makes the devices particularly expensive (both in terms of purchase and maintenance) and, above all, difficult to manufacture and use. In this context, the underlying technical problem of the present invention is to devise a radiographic imaging device that can substantially eliminate at least some of the aforementioned drawbacks. Within the scope of this technical problem, a key objective of the present invention is to obtain a radiographic imaging device that is smaller in size and easier to transport. Another objective of the invention is to provide a radiographic imaging device that is easy to use, in particular, enables precise and rapid centering with respect to the part being analyzed, and allows for the performance of several types of acquisitions. Another objective of the invention is to have an imaging device that is inexpensive and, above all, easy to manufacture and use. The technical challenges and specified objectives are achieved by the radiographic imaging device described in the subsequent detailed description. The characteristics and advantages of the invention will become apparent below by a detailed description of preferred embodiments of the invention with reference to the accompanying drawings.

In this document, measurements, values, shapes, and geometric references (such as perpendicularity and parallelism), when associated with words such as “approximately” or other similar terms such as “roughly” or “substantially,” are considered exceptions to errors or inaccuracies in measurements resulting from production and/or manufacturing errors, and, in particular, to slight deviations from the associated values, measurements, shapes, or geometric criteria.
