Abstract: The present invention relates to a portable probe for photoacoustic tomography, capable of performing line-by-line scanning or area-by-area scanning by using a small number of light inputs; and a real-time photoacoustic tomography device. The probe for photoacoustic tomography includes: a lens receiving light inputs from an optical fiber so as to make the same proceed as small diameter parallel light; a Powell lens receiving the small diameter parallel light and generating a line beam of a predetermined thickness, and allowing energy dispersed on a line to be uniform on the entire line; a lens making the line beam pass therethrough such that the line beam has a predetermined width and a reduced thickness so as to be line-focused at a target area; an acoustic reflection glass for separating, from a light path, an acoustic wave outputted from the target area; and an acoustic measurement unit for measuring acoustic strength.

Abstract: Disclosed is a mobile colposcopy device for early diagnosis of cervical cancer, which includes an insertion unit which is inserted into the vagina of a woman, has a penetrating hole formed in one end coming into contact with the uterus, and is provided with a capturing path communicating with the penetrating hole, a capturing unit which is provided in the insertion unit so as to capture the cervix through the capturing path, and a lighting unit which is provided on the capturing path of the insertion unit and irradiates a lighting to the cervix through the penetrating hole. According to the present disclosure, the mobile colposcopy device for early diagnosis of cervical cancer can be simply and easily used so as to perform cervical cancer screening using a mobile colposcopy without environmental constraints including hospitals and allows women to early diagnose cervical cancer.
