Abstract
A detection method includes obtaining, during operation of a surface density device, a first current pose of a radiation source of the surface density device and a second current pose of a ionization chamber of the surface density device; ascertaining a first pose deviation of the radiation source based on the first current pose; ascertaining a second pose deviation of the ionization chamber based on the second current pose; and determining whether the radiation source has undergone a pose change with respect to the ionization chamber based on the first pose deviation and the second pose deviation.
Claims11
A detection method of a surface density device comprising a radiation source and an ionization chamber spaced from the radiation source, the detection method comprising:
- obtaining, during operation of the surface density device, a first current pose of the radiation source and a second current pose of the ionization chamber;
- ascertaining a first pose deviation of the radiation source based on the first current pose;
- ascertaining a second pose deviation of the ionization chamber based on the second current pose;
- and
- determining whether the radiation source has undergone a pose change with respect to the ionization chamber based on the first pose deviation and the second pose deviation.
A detection means, comprising:
- an obtaining module configured to obtain, during operation of a surface density device, a first current pose of the radiation source of the surface density device and a second current pose of the ionization chamber of the surface density device;
- an ascertaining module configured to ascertain a first pose deviation of the radiation source based on the first current pose and a second pose deviation of the ionization chamber based on the second current pose;
- and
- a determining module configured to determine whether the radiation source has undergone a pose change with respect to the ionization chamber based on the first pose deviation and the second pose deviation.
