The invention discloses a telescopic dial caliper for a gamma camera. The telescopic dial caliper comprises a dial caliper body and an adjustable fixing nut, wherein the dial caliper body is fixed on a probe collimator, a push-and-pull handle and collimator scale marks are arranged on the end side of the dial caliper body, and a fixing elastic piece and a caliper traveling groove are arranged below the adjustable fixing nut. The telescopic dial caliper is applicable to accurate measurement of the small gamma camera probe collimator in human body thyroid portions, errors caused by approximate measurement of finger widths can be reduced, the thyroid area measurement is accurate, and calculation of the iodine 131 dosage of patients of hyperthyroidism can be facilitated.
Description
technical field [0001] The invention relates to accessories for medical equipment, and directly relates to a telescopic scale caliper for a small gamma camera in the department of nuclear medicine. Background technique [0002] The small gamma camera is one of the nuclear medicine imaging equipment, which is specially used for thyroid imaging. The distance between the probe collimator and the human thyroid gland requires about 5 cm for operation. There is no fixed scale for existing equipment to measure the distance between the probe collimator and the human thyroid gland, usually in the width of a finger (about three fingers) There is a large difference in the width of the fingers, and the size of the thyroid gland after imaging is also significantly different, which directly affects the calculation of the thyroid area, and then affects patients with hyperthyroidism. 131 Calculation of iodine dosage. Contents of the invention [0003] The purpose of the present inventio...
