X-ray diagnostic system preferable to two dimensional x-ray detection

An X-ray diagnostic system comprising:

• an X-ray generator configured to irradiate an X-ray through a subject to be imaged;
• a planar X-ray detector configured to detect the X-ray which has passed through the subject;
• a C-shaped arm of which a one end supports the X-ray generator and of which an other end angle-adjustably supports the X-ray detector;
• an arm holder configured to slidably and rotatably support the C-shaped arm;
• and
• a holder supporting mechanism configured to rotatably support the arm holder.

An X-ray diagnostic system comprising:

• an X-ray generator configured to irradiate an X-ray through a subject to be imaged;
• a two-dimensional X-ray detector having a curved detecting plane onto which the X-ray impinges, configured to detect the X-ray which has passed through the subject with the curved detecting plane and to output two-dimensional imaging signals corresponding to the detected X-ray;
• supporting/moving means for movably supporting the X-ray generator and the X-ray detector;
• and
• image processing means for converting the two-dimensional imaging signals detected through the curved detecting plane into two-dimensional signals of a planar plane that constitutes a tomogram of the subject.

An X-ray diagnostic system comprising:

• a two-dimensional X-ray detector configured to detect an X-ray passing through a subject to be imaged and configured to output two-dimensional imaging signals corresponding to the detected X-ray;
• and
• supporting means for detachably supporting the two-dimensional detector,
• wherein the two-dimensional X-ray detector comprises a plurality of X-ray detectors whose characteristics are different from each other, and the supporting means is constructed to exchangeably support the plurality of X-ray detectors.

An X-ray diagnostic system comprising:

• a couch configured to movably support a tabletop on which a subject to be imaged is laid;
• an X-ray generator that has an X-ray focus and is configured to irradiate an X-ray through the subject;
• a planar X-ray detector configured to detect the X-ray which has passed through the subject and configured to output two-dimensional imaging signals based on the detected X-ray;
• supporting means for supporting the X-ray generator and the X-ray detector;
• driving means for moving, view by view, at least one of spatial positions of the X-ray focus and the tabletop, thereby changing a relative spatial positional relationship between the X-ray focus and the subject;
• calculating means for calculating the relative spatial positional relationship between the X-ray focus and the X-ray detector for each view;
• processing means for obtaining a tomogram of the subject using the two-dimensional imaging signals detected view by view and the relative spatial positional relationship for each view,
• wherein the supporting means comprises;
• a C-shaped arm of which a one end supports the X-ray generator and of which an other end angle-adjustably supports the X-ray detector,
• an arm holder configured to slidably and rotatably support the C-shaped arm, and
• a holder supporting mechanism configured to rotatably support the arm holder.
