K9's Medical Scan Equipment

The compact medical scanner clings to Chronotis’s chest, its multiple sensor tendrils extending like thin metal fingers against his robes. Its surface glows faintly blue as K9 cycles through diagnostic modes, detecting erratic Gallifreyan heartbeat patterns. The device hovers just above the skin, its hum barely audible over the tense silence as Romana leans in, medical collar activated, translating the dying Professor’s final coded warnings into actionable intelligence.
