X-ray fluoroscopic imaging apparatus

An X-ray fluoroscopic imaging apparatus comprising:

• a stand placed on a floor surface;
• a support column support arm projecting from one side of the stand in a predetermined direction;
• a support column having a lower end mounted on the support column support arm, and supported by the support column support arm;
• an X-ray support arm projecting from an upper end of the support column in a direction parallel to the predetermined direction;
• an X-ray generator supported by the X-ray support arm;
• a first slide mechanism that is disposed between the support column support arm and the lower end of the support column and slides the lower end of the support column parallel to the predetermined direction with respect to the support column support arm;
• a second slide mechanism that is disposed between the upper end of the support column and the X-ray support arm and slides the X-ray support arm parallel to the predetermined direction with respect to the upper end of the support column;
• a controller that controls operations of the first and second slide mechanisms;
• and
• an operation unit that receives an instruction from a user to move the X-ray generator in the predetermined direction, wherein
• when the operation unit has received the instruction from the user to move the X-ray generator in the predetermined direction,
• the controller performs the following first mode and second mode in order,
• the first mode in which the controller operates the second slide mechanism to move the X-ray support arm in the predetermined direction with respect to the upper end of the support column, so that the X-ray generator is moved to the predetermined direction, and
• the second mode in which the controller operates the first slide mechanism to move the lower end of the support column at a predetermined first speed in the predetermined direction with respect to the support column support arm, while operating the second slide mechanism to move the X-ray support arm at a second speed smaller than the first speed in a direction opposite to the predetermined direction with respect to the upper end of the support column, so that the X-ray generator is moved in the predetermined direction.
