Abstract
There are disclosed a collimator, a radiation emitting assembly and an inspection apparatus. The collimator is configured to collimate radiation from a radiation emitter. One of the collimator and the radiation emitter is provided with a protrusion portion and the other is provided with a recess portion such that the protrusion portion is capable of being placed within the recess portion and the radiation emitter and the collimator are allowed to be arranged close to and connected with each other, and that the radiation passes through passages in the protrusion portion and the recess portion from the radiation emitter to the collimator.
Claims17
A collimator, configured to collimate radiation from a radiation emitter, the collimator comprising:
- a protrusion portion such that the protrusion portion is capable of being placed within a recess portion of the radiation emitter, wherein the collimator is allowed to be arranged close to and connected with the radiation emitter, and wherein the radiation passes through passages in the protrusion portion and the recess portion from the radiation emitter to the collimator, wherein the collimator includes at least two primary collimator components configured to provide a slit therebetween to collimate the radiation and defining a collimator outlet configured to emit the radiation;
- and the at least two primary collimator components are provided with the protrusion portion, and wherein the at least two primary collimator components are respectively provided with at least a pair of additional shield pieces on an outer side thereof opposite to an inner side facing the radiation.
A collimator, configured to collimate radiation from a radiation emitter, the collimator comprising:
- a recess portion configured such that a protrusion portion of the radiation emitter is capable of being placed within the recess portion, wherein the collimator is allowed to be arranged close to and connected with the part of the radiation emitter other than the protrusion portion with the protrusion portion being received within the recess portion of the collimator, and the radiation passes through passages in the protrusion portion and the recess portion from the radiation emitter to the collimator, wherein the collimator includes at least two primary collimator components configured to provide a slit therebetween to collimate the radiation and defining a collimator outlet configured to emit the radiation, wherein the at least two primary collimator components are provided with the recess portion, and wherein the at least two primary collimator components are respectively provided with at least a pair of additional shield pieces on an outer side thereof opposite to an inner side facing the radiation.
