Artificial Intelligence

Artificial intelligence (AI) is becoming a crucial component of healthcare to help augment physicians and make them more efficient. In medical imaging, it is helping radiologists more efficiently manage PACS worklists, enable structured reporting, auto detect injuries and diseases, and to pull in relevant prior exams and patient data. In cardiology, AI is helping automate tasks and measurements on imaging and in reporting systems, guides novice echo users to improve imaging and accuracy, and can risk stratify patients. AI includes deep learning algorithms, machine learning, computer-aided detection (CAD) systems, and convolutional neural networks.

New hope for ‘mechanically dynamic’ tissue that’s been damaged

Mechanical engineers have developed injectable hydrogels that can fuse with frequently moving tissues—like those of the heart, muscles and vocal cords—to repair damage and restore function.

Printed ‘skin’ hastens healing, lessens scarring

Researchers have demonstrated the 3D bioprinting of artificial human skin so lifelike it can quickly fuse with damaged tissue from the surface (epidermis) through the midlevel (dermis) and into the underlying fatty layer (hypodermis).
