Data-Dependent Higher-Order Clique Selection for Artery-Vein Segmentation by Energy Minimization [PDF]

International Journal of Computer Vision 117, 142-158(2016), 2023
We propose a novel segmentation method based on energy minimization of higher-order potentials. We introduce higher-order terms into the energy to incorporate prior knowledge on the shape of the segments. The terms encourage certain sets of pixels to be entirely in one segment or the other.

Total anomalous pulmonary vein drainage in a 60-year-old woman diagnosed in an ECG-gated multidetector computed tomography : a case report and review of literature [PDF]

, 2018
Purpose: Total anomalous pulmonary vein drainage (TAPVD) is a congenital cardiac defect in which there is no connection between pulmonary veins and the left atrium.

Automatic pulmonary artery-vein separation in CT images using a twin-pipe network and topology reconstruction [PDF]

PeerJ Computer Science, 2023
Background With the wide application of CT scanning, the separation of pulmonary arteries and veins (A/V) based on CT images plays an important role for assisting surgeons in preoperative planning of lung cancer surgery.

Numerical simulation of blood flow and pressure drop in the pulmonary arterial and venous circulation [PDF]

, 2014
A novel multiscale mathematical and computational model of the pulmonary circulation is presented and used to analyse both arterial and venous pressure and flow. This work is a major advance over previous studies by Olufsen et al. (Ann Biomed Eng 28:1281–

Blood vessels and their construction in the cavities of pulmonary tuberculosis [PDF]

, 1958
First of all, we investigated the origin, the construction and distribution of the bronchial arteries and veins in adult rabbits, and then observed various changes of the blood vessels in experimental cavities and caseous foci and also studied the ...

Cardiovascular agents affect the tone of pulmonary arteries and veins in precision-cut lung slices.

PLoS ONE, 2011
IntroductionCardiovascular agents are pivotal in the therapy of heart failure. Apart from their action on ventricular contractility and systemic afterload, they affect pulmonary arteries and veins. Although these effects are crucial in heart failure with

Efficient Uncertainty Quantification in a Multiscale Model of Pulmonary Arterial and Venous Hemodynamics [PDF]

, 2023
Computational hemodynamics models are becoming increasingly useful in the management and prognosis of complex, multiscale pathologies, including those attributed to the development of pulmonary vascular disease. However, diseases like pulmonary hypertension are heterogeneous, and affect both the proximal arteries and veins as well as the ...

Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]

, 2002
Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.
