Abstract—The corpus callosum is the largest commissural fiber in the cerebral hemisphere that lies at the bottom of the cerebral longitudinal fissure. The Agenesis of Corpus Callosum (ACC) is a congenital disease in the fetal central nervous system malformation, which means the partial or total loss of the corpus callosum during the formation and is detrimental to future development. Its symptom detection mainly depends on the ultrasonic diagnosis, but this method is highly dependent on the experience of doctors because different locations of the fetus and the resolution of the images bring difficulties to the detection of complete callosum. To solve this problem, this paper presents a fusing attention mechanism based on the deep learning method which takes in the advantages of Transformers and dual attention mechanism and realizes accurate semantic segmentation of fetal corpus callosum in ultrasonic images. This method successfully reached an Intersection over Union (IoU) of 59.4%. Besides, this paper also presents the comparison between the performances of different backbone networks and loss functions in order to provide a reference for the application of different parameters according to actual circumstances. Our work provides a reliable reference to locate corpus callosum, thus is promising for the improvement in the diagnosis of ACC and the reduction of the burden of medical workers.
