PitVis is one of five different sub-challenges proposed under the MICCAI 2023 EndoVis framework. Participants can obtain a training dataset of endoscopic pituitary surgery videos in PitVis, which includes annotations for steps and instruments in real-time. The evaluation of unseen test data will be conducted via Docker submission. The test data will not be released to participants. Note that the authors divided the original video data into image data and randomly split it into training and validation sets in an 8:2 ratio, with the image statistics reported in this paper reflecting the split data.
The pituitary gland, located at the base of the brain, is commonly referred to as the "master gland," performing essential functions required to sustain human life. The estimated prevalence of clinically relevant tumors on the pituitary is 1 in 1000 in the population, which can be life-limiting if untreated. Endoscopic pituitary surgery is considered the "gold standard" treatment method, entering directly through the nostril to excise the tumor directly. This surgery is particularly challenging due to the limited working space, which restricts the flexibility of vision and instrument manipulation, potentially leading to poor surgical techniques and adverse outcomes for the patient. Computer-assisted intervention can help overcome these challenges by providing guidance during the operation for senior surgeons and surgical teams, and support for junior surgeons during training.
