Abstract

The embodiment of the invention discloses a signal detection device and system, and the device comprises a collection module which is used for collecting an optical signal transmitted from a target object and carrying out the imaging of the optical signal, and the optical signal comprises a Cherenkov fluorescence signal; a positioning and supporting module used for positioning and supporting the acquisition module; a control module used for controlling the acquisition module and the positioning support module; a processing module used for carrying out image processing on the optical image obtained by the acquisition module, wherein the acquisition module comprises a probe used for detecting an optical signal; an optical fiber array used for transmitting an optical signal detected by the probe, wherein the diameter of the optical fiber array is 0.04-7mm; and an image sensor used for imaging the optical signals transmitted by the optical fiber array. By utilizing the signal detection device and system provided by the embodiment of the invention, the accuracy of a Cherenkov fluorescence detection result can be improved, so that a doctor is helped to carry out diagnosis.

Description

technical field [0001] The present application relates to the technical field of optical molecular imaging, in particular to a signal detection device and system. Background technique [0002] When the speed of high-speed charged particles traveling in a non-vacuum medium is greater than the speed of light in this non-vacuum medium, a kind of electromagnetic radiation, that is, Cherenkov radiation, will be produced, thereby emitting Cerenkov Luminescence (Cerenkov Luminescence) , referred to as CL). [0003] Cerenkov Luminescence Imaging (CLI) technology for imaging CL is a new imaging technology that has emerged in recent years. Cherenkov fluorescence and image it, so as to obtain the optical information of the corresponding organs in the human body, which solves the probe toxicity problem of traditional optical imaging. In addition, CLI technology has all the advantages of optical molecular imaging technology, such as high sensitivity, low cost, high time resolution, saf...
