You are to reference projection drawing (architecture), moving image (cinema) and radiology (medicine) to create CT scan as a dissection of both time and space.
Use your idea of notation 1 (section) as a point of departure by reinterpreting it or developing it. Focus on the revealing of the interiority of a space and its activity.
To consider (you don’t have to consider all, choose one or two):
qualitative and quantitative
Place and event
Physical and ephemeral
Abstract and realistic
Objective and subjective
Static and active
Keep it simple, yet exploratory. Be rigorous in your thinking. Reference CT scan as multiple “slices” (axial step and shot acquisition, cine acquisition, multislice…). The notation is to be between 30 and 90 seconds but consider length and time break down carefully. Time is a measuring system. Structure the notation in a measured manner adding graphics that mark data specific to each slide.
