Abstract

Endometrial carcinoma is an epithelial malignant tumor o the endometrium. At present, the conventional methods for endometrial carcinoma detection are cytologial smear and hysteroscopic endometrial biopsy. The hysteroscopic biopsy is a minimally invasive diagnostic and treatment technique in gynecology. However, it can only obtain the lesion of upper mucosa of the uterus by hysteroscopic endometrial biopsy, but cannot detect the infiltration depth of the lesions. Photoacoustic imagining is an imagining technique combining optical and ultrasound. It has both the high resolution of optical imaging and the deep detection depth of ultrasonic imaging. In our study, hysteroscopy-based photoacoustic imaging techniques were proposed to discuss the effect of pigeon intracavitary imaging. The results show that the detectable depth reaches 2.5 cm in our ultrasonic probe with hysteroscopy in vitro. And the longitudinal resolution is 0.5mm. So the system can effectively detect subcutaneous lesions in the cavity. The system is expected to play an important role in the early diagnosis and treatment monitoring of the uterine lesions.
