Nieuwe scanmethode keert objecten razendsnel binnenstebuiten
Live meekijken met een CT-scan in plaats van achteraf de beelden pas te analyseren. Als het aan de Leidse wiskundige Jan-Willem Buurlage ligt, is dat binnenkort realiteit. Hij ontwikkelt methodes om de algoritmes achter 3D-scans sneller te maken. Best een uitdaging: ‘Net als wiskundigen zijn computers…
