Assignment 6

Thank you!

Replace Random Forest with Deep Neural Net!

Classification

Regression

put samples into different classes

estimate values, "fitting"

0..1 ~ 0..90 degrees

Create fake images and tune them to look real!

GANs

Autoencoder

learn a compressed representation

Nuclear Imaging

track a path of a radioactive tracer

Single Photon Emission Computed Tomography

Positron Emission Tomography

SPECT

PET

different types of radiotracers

allow to identify normal and abnormal activity in living tissue

SPECT and PET

functional chemical changes

typically metabolic activities

both use radioactive tracers

carrier

radioactive atom

carrier binds to protein or sugar in the body

for example to detect a tumor

very similiar

SPECT: Gamma Rays

PET: Positron Imaging

both have low resolution!

Voxel size for CT: 0.625-1.25 mm^3

similar to MRI

0.1-1 mm^3

SPECT/PET 5-10mm^3

usually combined with CT scan
