Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. These rays are focused on irradiating abnormal or diseased tissues to cause focal necrosis or functional changes to achieve the purpose of treating diseases.

The role and status of radiotherapy in tumor treatment has become increasingly prominent, and it has become one of the main means of treating malignant tumors.
放射治疗成像设备如CT、CBCT或MRI等配合使用，用以确定病变组织的具***置，并因此确定病变组织相对射线的靶点。然而，放射性治疗成像设备和放射性治疗设备不是一体的，治疗定位过程比较复杂，定位误差较大，耗时也很长，延长了治疗的时间。且常规的放射治疗设备只能一个方向运动，限制了治疗束的角度，治疗束会无可避免的穿过比较多的人体组织细胞和脏器，使健康的人体组织细胞收到破坏和损伤。Radiation therapy imaging equipment such as CT, CBCT or MRI is used in conjunction to determine the specific location of the diseased tissue, and thus determine the target of the diseased tissue relative to the radiation. However, radiotherapy imaging equipment and radiotherapy equipment are not integrated, and the treatment positioning process is relatively complicated, with large positioning errors and a long time-consuming, which prolongs the treatment time. Moreover, conventional radiotherapy equipment can only move in one direction, which limits the angle of the treatment beam. The treatment beam will inevitably pass through more human tissue cells and organs, causing damage and damage to healthy human tissue cells.
