Abstract
The present invention relates to a kind of ray detecting device.The horizontal supporting plate, rotary drive mechanism, level frame and the horizontal drive mechanism that comprise signal processing system, radiographic source, collimation shield, detector, vertical rotation axis, driving radiographic source, collimation shield and detector by rotary drive mechanism rotates, driving radiographic source, collimation shield and detector by horizontal drive mechanism moves horizontally, regulate resolution by adjusting rotation and point-to-point speed, thereby solved the uncontrollable technical matters of existing ray detecting device resolution.
Description
Technical field
The present invention relates to a kind of ray detecting device.
Prior art
The picture resolution that the device of the existing structure of utilizing the X-ray detection X object forms is fixed, and imaging is clear inadequately, can not regulate resolution as required.
Summary of the invention
The present invention will solve is that picture resolution that existing ray detecting device forms is fixed and can not be regulated the technical matters of resolution as required.
In order to solve above technical matters, the present invention takes following two kinds of technical schemes:
A kind of ray detecting device, comprise signal processing system, radiographic source, collimation shield and detector, radiographic source is positioned at the collimation shield, the collimation shield is provided with collimating aperture, it is characterized in that, the horizontal supporting plate that also comprises a band vertical rotation axis, rotary drive mechanism, level frame and horizontal drive mechanism, described detector is positioned on the periphery of described collimating aperture outlet, described collimation shield and detector are arranged on the horizontal supporting plate, described vertical rotation axis is connected with described rotary drive mechanism, described horizontal supporting plate and described level frame are slidingly connected, and do horizontal rectilinear motion by the horizontal supporting plate of described horizontal drive mechanism's driving on level frame.
Described level frame is two parallel linear guides, and described horizontal drive mechanism is motor and drive lead screw.
A kind of ray detecting device, comprise signal processing system, radiographic source, collimation shield and detector, radiographic source is positioned at the collimation shield, the collimation shield is provided with collimating aperture, it is characterized in that, the horizontal supporting plate that also comprises a band vertical rotation axis, rotary drive mechanism, level frame and horizontal drive mechanism, described detector is positioned on the periphery of described collimating aperture outlet, described collimation shield and detector are arranged on the level frame and are slidingly connected with described level frame, and driving the collimation shield and detector is done horizontal rectilinear motion on level frame by described horizontal drive mechanism, described vertical rotation axis is connected with described rotary drive mechanism.
Described level frame is two parallel linear guides, and described horizontal drive mechanism is motor and drive lead screw.
After having adopted technique scheme, owing to adopted rotation and translation to produce beam, realized flying-spot scanner, can regulate resolution by adjusting rotation and point-to-point speed, thereby solved the uncontrollable technical matters of existing ray detecting device resolution, in addition, because detector and radioactive source, have solved detector and radioactive source need to fixedly connected arm because of palpus is synchronous technical matters in the same side.
