Embodiment Construction

[0018] The present disclosure relates to a system for imaging subcutaneous blood flow in tissue using laser speckle contrast imaging techniques. Although the disclosure will be described in terms of specific illustrated embodiments, it will be apparent to those skilled in the art that various modifications, rearrangements, and substitutions can be made without departing from the spirit of the disclosure. The scope of the present disclosure is defined by the claims appended hereto.

[0019] figure 1 Shown is a laparoscopic system 100 capable of imaging subcutaneous blood flow using lasers and imaging inside a patient using white light. The system 100 includes a display device 110 , a computing device 120 , a laparoscope 130 , a white light source 140 , a switch 150 , and a laser source 160 . Display device 110 receives a video signal from computing device 120 and displays the video signal. The display device 110 may be of any form suitable for displaying medical images. The...

Abstract

A laparoscopic apparatus (100) for imaging subsurface blood flow of tissue, the laparoscopic apparatus (100) including a light source (140) emitting white light via a light guide, a laser source (160) emitting laser light via an optical fiber (164) and a laparoscope (130) that alternatively receives reflected laser light emitted from the laser source (160), and reflected white light emitted from the light source (140). The apparatus (100) further includes a computing device (120) receives the sensed resulted from the laparoscope (130) and generates laser speckle contrast images or white light images according to an output status of the light source (140) and the laser source (160), and a display (110) that is operatively associated with the computing device (120) and that displays at least one of the laser speckle contrast images and the white light images, where the laser speckle contrast images show the subsurface blood flow.

Description

technical field [0001] The present disclosure relates to a system for imaging blood flow. More particularly, the present disclosure relates to a system for imaging subcutaneous blood flow in tissue with a large field of view. Background technique [0002] In recent years, surgery on internal organs has increased significantly due to improvements in medical diagnosis, physician's operating techniques, medical devices, and medical systems. Because adequate blood flow is critical after surgery to promote healing and avoid organ leakage, it is also important to visually spot and confirm the exact site of surgery. Laparoscopic surgery leaves a relatively small sutured wound on the skin compared to thoracotomy, which results in less pain and a shorter recovery time than thoracotomy. For this reason, more and more patients and physicians are more inclined to choose laparoscopic surgery rather than thoracotomy. [0003] During laparoscopic surgery, accurate joint position is an i...
