We proposed a novel algorithm for instrument segmentation in the robot-assisted laparoscopic surgery (RALS) images, which will be used for tool tracking to automatically preventing hazardous situations. The proposed algorithm achieved 1mm range of average RMSE of tool tip position in various conditions, which is significantly lower value compared to the previous methods.

Post-traumatic orbital reconstruction remains a surgical challenge and requires careful preoperative planning, sound anatomical knowledge and good intraoperative judgment. Computer-assisted technology has the potential to reduce error and subjectivity in the management of these complex injuries. A systematic review of the literature was conducted to explore the emerging role of computer-assiste...

In computer-assisted surgery (CAS), optical digitizing is state-of-the-art. Unfortunately standard navigation instruments, e.g. small, LED-equipped pointers are frequently shadowed by the operating microscope when the camera-array is ceiling- or rack-mounted. Thus, for microsurgery, a navigation module consisting of a reference panel mounted onto the housing of the microscope and an object dist...

leiomyoma is a rare esophageal tumor that constitutes less than 1% of esophageal malignancies. it should be removed when diagnosed even if asymptomatic. this study presents two cases of esophageal leiomyoma in 38 and 62 years old men who presented with dysphagia and evaluated for diagnosis and location of related tumors. patients were clinically examined and upper gastrointestinal endoscopy, ch...

objective: the aim of the current study was to assess the impact of computer games and computer-assisted type instruction on dictation scores of elementary school children with attention deficit – hyperactivity disorder (adhd). method: in this single-blind clinical trial, 37 elementary school children with adhd, selected by convenience sampling and divided into group i (n=17) and group ii (n=20...

CONCLUSION The use of the bone anchoring device associated with a fiducial marker, both fixed close to the operating field, improves the reproducibility and effectiveness of the computer-assisted navigation in lateral skull base surgery. OBJECTIVES Computer-assisted navigation in lateral skull base surgery using the electromagnetic system Digipointeur(®) needs an external fiducial marker (tit...
