Cephalometric Landmark Detection by AttentiveFeature Pyramid Fusion and Regression-Voting [PDF]

arXiv, 2019
Marking anatomical landmarks in cephalometric radiography is a critical operation in cephalometric analysis. Automatically and accurately locating these landmarks is a challenging issue because different landmarks require different levels of resolution and semantics. Based on this observation, we propose a novel attentive feature pyramid fusion module (

The optimum angle-cut of collimator for the dense objects in high-energy proton radiography [PDF]

, 2015
The use of the minus identity lenses with the angle-cut collimator can achieve high contrast image in high-energy proton radiography. This article presents the principle of choosing the angle-cut aperture of the collimator for the different energies and objects.

Successful Removal and Replacement of a Stuck Hemodialysis Catheter via Thoracotomy: Report of Two Cases and Literature Review

Case Reports in Nephrology and Dialysis
Introduction: Stuck tunneled central venous catheters (CVCs) have been increasingly reported. In rare cases, the impossibility of extracting the CVC from the central vein after regular traction is the result of rigid adhesions to the surrounding fibrin ...

RTEX: A novel methodology for Ranking, Tagging, and Explanatory diagnostic captioning of radiography exams [PDF]

arXiv, 2020
This paper introduces RTEx, a novel methodology for a) ranking radiography exams based on their probability to contain an abnormality, b) generating abnormality tags for abnormal exams, and c) providing a diagnostic explanation in natural language for each abnormal exam. The task of ranking radiography exams is an important first step for practitioners
