HemoSet: The First Blood Segmentation Dataset for Automation of Hemostasis Management [PDF]

arXiv
Hemorrhaging occurs in surgeries of all types, forcing surgeons to quickly adapt to the visual interference that results from blood rapidly filling the surgical field. Introducing automation into the crucial surgical task of hemostasis management would offload mental and physical tasks from the surgeon and surgical assistants while simultaneously ...

Automatic Tip Detection of Surgical Instruments in Biportal Endoscopic Spine Surgery [PDF]

arXiv, 2019
Some endoscopic surgeries require a surgeon to hold the endoscope with one hand and the surgical instruments with the other hand to perform the actual surgery with correct vision. Recent technical advances in deep learning as well as in robotics can introduce robotics to these endoscopic surgeries.

A CT-guided Control Framework of a Robotic Flexible Endoscope for the Diagnosis of the Maxillary Sinusitis [PDF]

arXiv
Flexible endoscopes are commonly adopted in narrow and confined anatomical cavities due to their higher reachability and dexterity. However, prolonged and unintuitive manipulation of these endoscopes leads to an increased workload on surgeons and risks of collision.

BrightVAE: Luminosity Enhancement in Underexposed Endoscopic Images [PDF]

arXiv
The enhancement of image luminosity is especially critical in endoscopic images. Underexposed endoscopic images often suffer from reduced contrast and uneven brightness, significantly impacting diagnostic accuracy and treatment planning. Internal body imaging is challenging due to uneven lighting and shadowy regions.

Helicobacter pylori: types of diseases, diagnosis, treatment and causes of therapeutic failure [PDF]

, 2016
Acute upper gastrointestinal lesions have a multifactorial etiology but, regardless of the cause, they are related to mucosal barrier destruction. Since Helicobacter pylori induces a superficial chronic gastritis with the infiltration of neutrophils in ...
