X-ray generating apparatus and imaging device

An X-ray generation apparatus, comprising:

• a casing;
• a heat-conduction member arranged through the casing, and having a through-channel configured to circulate a cooling medium;
• and
• an anode target configured to receive electron bombardment to generate X-rays, arranged in the casing, and surrounding the heat-conduction member in a rotatable fashion;
• a first cathode connected to the casing, wherein the casing has a first transmission part, and the first cathode is arranged to correspond to the anode target so that electrons produced by the first cathode bombard the anode target in order to generate X-rays, and the X-rays exit the casing through the first transmission part;
• and
• a second cathode connected to the casing, wherein the casing also has a second transmission part, and the second cathode is arranged to correspond to the anode target so that electrons produced by the second cathode bombard the anode target in order to generate X-rays, and the X-rays exit the casing through the second transmission part.
