Virtual Biopsy
Software that uses spectroscopy to measure chemical levels in the brain to detect abnormalities.
MULTIVOXEL
CHALLENGE
Redesign an interface for radiologists that visualizes data from spectroscopy.
WHAT?
Spectroscopy is data outputed from MRI machines. This data looks like the graph to the left. Each peak represents a different chemical. By knowing chemical levels, and how they change over time a patient can be diagnosed and properly treated in record time.
PROBLEM
Extremely difficult to read, even for professional radiologists.

AFFINITY DIAGRAM
Created to break down contextual inquiry and discover pain points, patters and needs.
Mapped out the journey of the radiologist (who would use the software) and Brainspec. This was done to understand all the people that will have touchpoints and how the software fits into the current medical system.

PROTOTYPING
sketching and iterating
After all of the research and understanding Spectroscopy, I delivered several final compositions based on main uses.
SINGLE VOXEL
Color coded to highlight low and high measurements.
​
Ability to dig deeper into each chemical
​
Ability to only look at specific metabolites that are relevant for the patient
Display 2 voxels at once to be able to compare
MULTI VOXEL
Compare 2 scans from the same patient to see his/her multi voxel data over time.
