Implementations of 3D Technology in Medical Imaging – Part 3

From the early days of CT scanners and mammography devices, medical imaging has come a long way. With the help of 3D medical imaging, healthcare professionals can now access new angles, resolutions and details that offer an all-around better understanding of the body part in question, all while cutting the dosage of radiation for patients.


Researchers at Massachusetts General Hospital are leading an effort in 3D computed tomography angiography (CTA). It can empower medical professionals to visualize arterial and venous vessels via a CT technique. They use CTA to map stenoses, aneurysms, dissections and other vascular anomalies. With the help of 3D imaging, medical professionals can get a better sense of what they’re viewing in anatomy and pathology, as well as any potential artefacts. Moreover, although MRIs and CT scans start out as 2D, they can be transformed into 3D through manipulation in 3D software. You can take a stack of 2D data sets and manipulate it in 3D in a variety of different ways.

With 3D ultrasound, ultrasonographers use a probe to examine a patient’s anatomy. They capture 3D image sweeps in addition to key snapshots and send the images to a 3D workstation. A 3D ultrasound technologist then reviews the images and creates additional 3D views before they go to the radiologist. The technologist will see whether the sonographer has captured the entire anatomy with the scan, if there’s poor image quality or if they have missed anything and they can have the ultrasonographer update the scan if necessary.
