Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...

📢📢📢 DSCA: A Public Digital Subtraction Angiography (DSA) Dataset for Cerebral Artery Segmentation 🧠🧠🧠. The DSCA dataset consists of 58 patients with 224 DSA sequences, including 1792 images from the left and right hemispheres. Among them are 28 male and 30 female patients, with ages ranging from 9 to 81 years and an average age of 49.

2025年1月21日 · Digital subtraction angiography (DSA) is a fluoroscopic technique used extensively in interventional radiology for visualization of blood vessels. Radiopaque structures such as bones are digitally eliminated ("subtracted") from the image, thus allowing for an accurate depiction of the blood vessels.

2023年9月1日 · The main research contents include: enhancing, segmenting, and reconstructing DSA images of the cardiovascular system, and performing vascular information fusion on multiple image frames in DSA dynamic images to improve the clarity and accuracy of DSA images.

The Digital Subtraction Angiography (DSA) technique can be applied to a fluoroscopy series (XA) to allow you to visualize blood vessels better. The pre-contrast image (so-called mask) is subtracted from the subsequent images in which the arteries/veins are filled with the contrast media and, thus, the bony or dense soft-tissue areas are removed ...

2019年7月31日 · Digital subtraction angiography (DSA) is a powerful technique for diagnosing cardiovascular disease. In order to avoid image artifacts caused by patient movement during imaging, we take deep learning-based methods to generate DSA image from single live image without the mask image.

2022年5月23日 · During thrombectomy, 2D digital subtraction angiography (DSA) image sequences are acquired simultaneously from the posterior-anterior and the lateral view to control whether thrombus removal was successful, and to possibly detect newly occluded areas caused by thrombus fragments split from the main thrombus.

Digital subtraction angiography (DSA) of the left vertebral artery shows a focal area of stenosis (arrow).

2019年9月30日 · Objective: To establish a digital subtraction angiography (DSA) information management and image analysis system to realize scientific management of DSA image information and efficient processing of image data.

In this research, automatic digitization and subtraction of X-ray angiographic images for coronary artery is performed to enhance the visualization of blood vessels and to find out the lesions in...
