A radiologist from Yale School of Medicine recently returned to his home country of Tanzania to help modernize a radiology unit at a local hospital, reports Yale News.

In many countries, however, operating an effective medical imaging program is much more challenging. Many imaging programs worldwide still use hard-copy film, which is expensive, frequently in short supply, and not as easily and quickly shared as digitized images.

To help remedy this, Dr. Frank Minja, assistant professor of radiology and biomedical imaging at Yale School of Medicine, traveled to Tanzania, Africa in 2014 to implement a Picture Archiving and Communication System (PACS), a medical imaging technology that provides economical storage and convenient access to medical images including x-rays, ultrasounds, CTs, and MRIs.
