Abstract

An diagnostic X-ray radiography device and system whereby a subject (M) can be placed on and taken off of an imaging bed safely, easily, and comfortably. In the device and system a placement-accommodating-state memory (21) stores a plurality of placement-accommodating states each consisting of an imaging bed (1) position and orientation and an X-ray tube (4) position that accommodate a given placement state of the subject (M). A placement-accommodating-state control unit (22) is provided that, if a desired placement-accommodating state is specified from among the plurality of placement-accommodating states by means of a control panel (11), makes the position of the imaging bed (1) and the position of the X-ray tube (4) conform to the specified placement-accommodating state. A placement-accommodating state is thus set automatically, so that the subject (M) can be placed and removed from the imaging bed (1) easily without a collimator (4a) attached to the X-ray tube (4) getting in the way.

Dependent claims

An X-ray diagnostic device, comprising:

a table operative to receive an external subject for scanning;
a table driving system operative to change a position-and-posture state by changing at least one of a position of said table and a posture of said table during a use thereof;
an X-ray radiographic system including an X-ray radiation module and an X-ray detection module facing each other and operatively sandwiching said table and positioned on either proximate side thereof;
an X-ray radiation module driving system operative to position the X-ray radiation module along a perpendicular direction relative to a plane of said table;
a suitable state for loading and unloading memory module operative to store a position-and-posture state of said table being suitable for a loading and unloading said external subject and a position of said X-ray radiation module as a suitable state for loading and unloading in advance of said use;
a suitable state for loading and unloading control system operative to control said table driving module and said X-ray radiation module driving system as a position-and-posture state of said table and a position of said X-ray radiation module coinciding with a suitable state for loading and unloading stored in said loading and unloading state storage module;
an input module operative to input a direction to the suitable state for loading and unloading control module during said use;
an X-ray radiographic system moving system operative to change the position of said X-ray radiographic system along a longitudinal direction of the table;
wherein said suitable state for loading and unloading storage module also operatively stores the position of said X-ray radiographic system being suitable for loading and unloading said external subject;
said suitable state for loading and unloading control system operatively controlling said X-ray radiographic moving system as the position of said X-ray radiographic module also coincides with a suitable state for loading and unloading;
wherein said suitable loading and unloading control module controls said table driving module and said driving module for the X-ray radiation module operative so that both said table and said X-ray radiation modules are operative while a direction from said input module is ongoing, and
wherein, afterward when there is no ongoing direction from said input module, said device ceases operations other than said driving module for the X-ray radiation driving module and also operatively controls said X-ray radiation module for continuous operation thereof.

#Reference will now be made in detail to embodiments of the invention. Wherever possible, same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps. The drawings are in simplified form and are not to precise scale. The word ‘couple’ and similar terms do not necessarily denote direct and immediate connections, but also include connections through intermediate elements or devices. For purposes of convenience and clarity only, directional (up/down, etc.) or motional (forward/back, etc.) terms may be used with respect to the drawings. These and similar directional terms should not be construed to limit the scope in any manner. It will also be understood that other embodiments may be utilized without departing from the scope of the present invention, and that the detailed description is not to be taken in a limiting sense, and that elements may be differently positioned, or otherwise noted as in the appended claims without requirements of the written description being required thereto.

#Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding embodiments of the present invention; however, the order of description should not be construed to imply that these operations are order dependent.

#Referring to FIG. 1, an X-ray fluoroscopic device of one Embodiment of the medical X-ray diagnostic device of the present invention is provided. FIG. 1 is a block diagram illustrating the total system of the X-ray fluoroscopic device relative to Embodiment.
