In this lecture from Yale's Introduction to Medical Software, Professor Mariam Aboian gives a practical demonstration of two widely used clinical technologies: Electronic Health Records systems and Picture Archiving and Communication Systems used for storing and viewing medical imaging. The session shows how these platforms function in day-to-day clinical practice, illustrating how software directly shapes how physicians access patient histories and diagnostic images. Aboian's demonstration grounds the course's regulatory and lifecycle material in a concrete, real-world tool that students may encounter in health-technology careers. The lecture gives students a tangible sense of the systems the earlier regulatory lectures are ultimately built to govern, bridging compliance theory with clinical software practice.
