The invention discloses a linear track tomography device and a perspective imaging device, relates to the technical field of radiation imaging, and in particular relates to a linear track tomography device. The linear track tomography device comprises a ray generation unit, a to-be-checked object channel, a first collimator and a ray receiving unit, wherein the ray generation unit is used for generating ray bundles positioned in a specific opening angle range a to-be-checked object passes through the to-be-checked object channel the first collimator and the radio receiving unit are arranged at two sides of the to-be-checked object channel the ray bundles sequentially pass through the first collimator and the to-be-checked object and are received by the ray receiving unit the ray generation unit is stationary and the first collimator and the radio receiving unit perform linear motion in the same direction, and the motion direction of the first collimator and the ray receiving unit is parallel to the to-be-checked object channel. According to the linear track tomography device disclosed by the invention, only at least one ray receiving unit is used, so that tomography can be finished. Therefore, the structure of the linear track tomography device is simplified, and the realization cost of the linear track tomography device is reduced.
