Apparatus for making tomographic images

An apparatus for making transmission and/or emission recordings of an object using radiation, the apparatus comprising:

• a radiation source;
• a camera sensitive to radiation from the radiation source and to emitted radiation from the object, the radiation and the emitted radiation having different energy levels;
• a collimator arranged between the radiation source and the camera;
• radiation-directing means which ensure that the radiation of the radiation source is radiated in a planar radiation beam so that the camera is illuminated according to a substantially line-shaped irradiation pattern;
• and
• means for moving the line-shaped irradiation pattern over the camera in a direction substantially perpendicular to the longitudinal direction thereof;
• wherein the collimator is fixed relative to the camera;
• and
• wherein the collimator is a focused fan beam collimator.

An apparatus for making combined transmission and emission recordings of an object using radiation, the apparatus comprising:

• a radiation source;
• a camera sensitive to radiation from the radiation source and to emitted radiation from the object, the radiation and the emitted radiation having different energy levels;
• a collimator arranged between the radiation source and the camera;
• radiation-directing means which ensure that the radiation of the radiation source is radiated in a planar radiation beam so that the camera is illuminated according to a substantially line-shaped irradiation pattern;
• and
• means for moving the line-shaped irradiation pattern over the camera in a direction substantially perpendicular to the longitudinal direction thereof;
• wherein the collimator is fixed relative to the camera;
• and
• wherein the collimator is a focused cone beam collimator.
