Megjegyzések:	Background Endoscopic surgery of fibroids is definitive and feasible way of therapy in symptomatic cases. Intramural fibroids located in the deep myometrium cannot be seen by naked eye, or palpated by laparoscopic, or hysteroscopic instruments. Avoiding unnecessary incisions on the uterine wall, it is important to localize precisely the fibroids pre- and intra-operatively. Augmented reality is used more and more fields of everyday life. Applying these methods can help in combining preoperative information with endoscopic video. Using MRI has been published for this function. Costs of MRI are high and availability is limited compared to ultrasonography. With a newly invented technique preoperatively ultrasonographic scanned data can be projected on the real-time video showing the exact localization of the fibroid. Methods During the preoperative work-up a 3D ultrasound scan is performed of the uterus. The result of this imaging system is stored in DICOM format and it contains information about the 3D volume of the uterus. The proposed method can extract and construct automatically the 3D model of the investigated uterus. Then, fibroid can be marked manually by surgeon in this model. Finally, using the manually selected (at least three) reference points for the registration of the different modalities, the proposed methods performs the necessary affine transformations on the 3D uterus model and project to the video frame. In this way, by the technique of the augmented reality, a previously scanned uterus with fibroid in the deep myometrium is projected on the video fame of a video taken during endoscopic surgery. Results In two cases of intramural fibroid this new technique was used. By applying augmented reality during one-one cases of laparoscopic and hysteroscopic surgery fibroid was identified. Resecting fibroid happened by one incision. Conclusions Using the advantages of augmented reality, finding and localizing fibroid is easier during endoscopic surgery. Ultrasonography is widely available procedure with lower costs. Preoperative ultrasonographic scan can help in fibroid identifying and localizing procedures. Performing the proper incision, without any others unnecessary ones, complication rate, blood loss and duration of operation can be significantly reduced.
