Irradiation apparatus

An irradiation apparatus, comprising:

• a shielded housing;
• a plurality of ionising radiation source points configured to output ionising radiation, wherein the plurality of ionising radiation source points is a first array distributed around an irradiation volume and the first array of ionising radiation source points is configured to direct ionising radiation inwardly to the irradiation volume;
• a transport apparatus configured to support at least one sample to be irradiated, wherein the transport apparatus is configured to transport samples along a linear path through the irradiation volume;
• a detector array;
• and
• a controller configured to control operation of the plurality of ionising radiation source points and the detector array,
• wherein the controller is configured to:
• image the irradiation volume using at least one of the ionising radiation source points of the first array and the detector array to acquire image data of the at least one sample within the irradiation volume;
• or
• image an imaging volume to acquire image data of the at least one sample within the imaging volume, wherein the irradiation volume is linearly offset from the imaging volume along the linear path, the irradiation apparatus comprising a second array of ionising radiation source points distributed around the imaging volume, the second array of ionising radiation source points configured to output ionising radiation, and the controller is configured to image the imaging volume using the second array of ionising radiation source points and the detector array;
• and
• irradiate the at least one sample within the irradiation volume by controlling the plurality of ionising radiation source points of the first array based on the acquired image data.
