Parathyroid gland function imaging method and system, and endoscope

Abstract

The invention discloses a parathyroid gland function imaging method and system, and an endoscope. The method comprises the following steps: outputting visible light and laser through the endoscope to irradiate parathyroid glands, generating near-infrared fluorescence, and reflecting the near-infrared fluorescence together with the visible light and the laser into an endoscope probe; separating the visible light, the near-infrared fluorescence and the laser input by the endoscope probe; acquiring and obtaining a parathyroid gland color image, a near-infrared fluorescence image and laser speckles; performing decorrelation processing to obtain a decorrelated speckle pattern; and acquiring an image which is fused by the near-infrared fluorescence image and the color image and an image which is fused by the decorrelated speckle image and the color image in virtue of a fusion registration technology. According to the invention, near-infrared fluorescence is applied in the endoscope to position the parathyroid glands, laser speckles are used for detecting blood supply of the parathyroid glands, a decorrelation algorithm is used for processing the laser speckles, and the fusion registration technology is combined for use, so a decorrelated speckle fusion image of the parathyroid glands is displayed to guide parathyroid gland function diagnosis in thyroid surgery.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a parathyroid functional imaging method, system and endoscope. Background technique [0002] The incidence of thyroid tumors is increasing year by year, and thyroid cancer has become the first malignant tumor in the head and neck. After radical surgery for these thyroid cancers, a considerable number of patients have transient hypoparathyroidism, followed by hypocalcemia. Some studies report that the incidence rate is as high as 47%; about 3% of the patients have permanent hypoparathyroidism and blood calcium regulation disorder. Hypocalcemia can lead to cardiac arrhythmias, muscle spasms, convulsions, and in severe cases, can eventually lead to death. This complication brings huge economic and physical and mental burdens to patients and their families, which is also one of the main reasons for malpractice lawsuits after thyroid surgery. [0003] The parathyroid gland is the smal...
