Here we propose a cone-beam composite-circling mode to solve the quasi-short object problem. which is to reconstruct a short portion of a long object from longitudinally truncated cone-beam data involving the short object. In contrast to the saddle curve cone-beam scanning. the proposed scanning mode requires that the X-ray focal spot undergoes a circular motion in a plane facing the ... https://halohealthcarers.shop/product-category/crutch-asseccories/
