Ultrasound (US) imaging is a first-line medical imaging modality for detecting thyroid cancer; however, it suffers from operator-dependent variability in image quality and diagnostic accuracy. To address this issue, various robotic US systems have been proposed to assist in thyroid US examinations.
This study proposes a method for finding a parasternal long-axis view in echocardiography autonomously with a robotic ultrasound (US) system. In obtaining this view, it is necessary to avoid the ribs and lungs because they reduce the clarity of US image. Meanwhile, the anatomical position and size o
During auscultation, patients in difficult age often feel embarrassed and uncomfortable when exposing their chests to doctors of the different gender and being touched physically by doctors. We assume that an auscultation with robot technology can address the aforementioned gender-related issue. Tow…
Autonomous fetal ultrasonography with a robotic ultrasound (US) can potentially solve the issue of the shortage of ob-gyn physicians in prenatal care. In fetal cardiac diagnosis, acoustic shading derived from the fetal skeleton makes the scanning procedure using a robotic US cumbersome. We hypothesi…
A computed tomography (CT)-guided robotic needle requires registration to transfer coordinates between the robot and CT image for accurate insertion. In our previous work, we proposed a geometric marker that allows direct registration between a CT image and robot and demonstrated its proof of concep…
Novel severe acute respiratory syndrome coronavirus 2 (COVID-19) has become a pandemic of epic proportions, and global response to prepare health systems worldwide is of utmost importance. 2-dimensional (2D) lung ultrasound (LUS) has emerged as a rapid, noninvasive imaging tool for diagnosing COVID-
Fine needle insertions into a lung are challenging in terms of the needle deflection due to the breathing motion. Although previous related works neglected the effect for the needle deflection due to the breathing motion by patients stopping the breath during the insertion, they have to suffer from…
Fine needle deflection is a problem encountered during insertion into a soft tissue. Although an axial rotational insertion is an effective approach for minimizing this problem, needle deflection still depends on the insertion angle with respect to the tissue boundary. Since the human body consists
Accurate insertion of fine needles is difficult due to needle deflection. Needle deflection in the lower abdomen is particularly complex, as the needle has to pass through various tissues. As the area of the bowel is dominant in lower abdominal insertion, it is important to analyze the deflection du…
Fine needles can easily be deflected, making accurate needle insertion into a tumor difficult. In particular, it is difficult to insert the needle into a tumor in the lower abdomen because the needle has to pass through various tissues. Therefore, for lower abdominal needle insertion, we intend to d
