Positioner for an x-ray examination apparatus

A positioner for an x-ray examination apparatus, said positioner comprising:

• a base;
• an arm having a first end and a second end;
• a first axle rotatably connecting said first end of said arm to said base;
• a curved carrier having a first end at which an x-ray tube is mounted and a second end at which an x-ray receiver is mounted facing said x-ray tube with a central x-ray proceeding between said x-ray tube and said x-ray receiver;
• a holder in which said curved carrier is displaceably mounted;
• a second axle rotatably connecting said second end of said arm to said holder;
• and
• an imaginary extension of said first axle and an imaginary extension of said second axle both intersecting said central ray at a common point in all positions of said arm and said carrier, said first axle being oriented parallel to a horizontal plane.

A positioner for an x-ray examination apparatus, said positioner comprising:

• an examination table having a longitudinal center axis and being displaceable along said longitudinal center axis;
• a base;
• an arm having a first end and a second end;
• a first axle rotatably connecting said first end of said arm to said base;
• a curved carrier having a first end at which an x-ray tube is mounted and a second end at which an x-ray is mounted facing said x-ray tube with a central x-ray proceeding between said x-ray tube and said x-ray receiver;
• a holder in which said curved carrier is displaceably mounted;
• a second axle rotatably connecting said second end of said arm to said holder;
• and
• an imaginary extension of said first axle and an imaginary extension of said second axle both intersecting said central ray at a common point in all positions of said arm and said carrier, said base being oriented so that said first axle and said imaginary extension of said first axle form an acute angle with said longitudinal center axis.

A positioner for an x-ray examination apparatus, said positioner comprising:

• a base;
• an adjustable-length arm having a first end and a second end;
• a first axle rotatably connecting said first end of said arm to said base;
• a curved carrier having a first end at which an x-ray tube is mounted and a second end at which an x-ray is mounted facing said x-ray tube with a central x-ray proceeding between said x-ray tube and said x-ray receiver;
• a holder in which said curved carrier is displaceably mounted;
• a second axle rotatably connecting said second end of said arm to said holder;
• and
• an imaginary extension of said first axle and an imaginary extension of said second axle both intersecting said central ray at a common point in all positions of said arm and said carrier.

A positioner for an x-ray examination apparatus, said positioner comprising:

• a base;
• an arm having a first end and a second end;
• and
• a longitudinal axis;
• means for attaching said arm to said base for allowing displacement of said arm along said longitudinal axis a first axle rotatably connecting said first end of said arm to said base;
• a curved carrier having a first end at which an x-ray tube is mounted and a second end at which an x-ray is mounted facing said x-ray tube with a central x-ray proceeding between said x-ray tube and said x-ray receiver;
• a holder in which said curved carrier is displaceably mounted;
• a second axle rotatably connecting said second end of said arm to said holder;
• and
• an imaginary extension of said first axle and an imaginary extension of said second axle both intersecting said central ray at a common point in all positions of said arm and said carrier.
