摘要： A flying spot forming apparatus includes a radiation source and a shielding body. A side wall of the shielding body is provided with at least two pairs of helical grooves. Each helical groove is provided with a predetermined slope. A first incident groove is adjacent to a second incident groove. A head end of the first incident groove is higher than a head end of the second incident groove. A tail end of the first incident groove is higher than a tail end of the second incident groove. The tail end of the first incident groove is not higher than the head end of the second incident groove. A first axial cross section of the shielding body intersects with the tail end of the first incident groove. A second axial cross section intersects with the head end of the second incident groove.
