Marius' Encephalograph

A portable diagnostic device with a flexible, arched arm terminating in a small sensor array, deployed by Marius in the isolation ward to monitor the Doctor’s brain activity. The compact machine hums with quiet urgency as its probes attach to the Doctor’s temples, measuring neural impulses and scanning for anomalies in his comatose state. K9’s analysis cross-references its encephalographic readings with his own scans, revealing the Doctor’s alien physiology and the viral lodging in his mind-brain interface.

Doctor exposed as virus carrier saves TARDIS

Marius’ portable encephalograph is deployed urgently to scan the Doctor’s brain activity, its arched sensor array attaching to the temples to measure impulses. The machine hums urgently as it cross-references data with K9’s output, visually displaying alien neural patterns and confirming the viral seat in the mind-brain interface despite the Doctor’s coma.

Before: Stored in ward equipment stock; brought into use upon seeing K9’s initial data
After: Active monitoring device attached to Doctor, still generating data
