Quantitative Imaging is Essential in Cancer Care:
Tumor Characteristics:
• Size (+):
o 2-D: RECIST 1.1
o 3-D: Volumetric Assessment
o Potential: Shape / Peri-Tumor Zone / Relationships - ?3D Printing?
• Histopathology:
o Tissue Heterogeneity: e.g. Textural Analysis
o Tissue Mechanical Properties: e.g. Stiffness by MR
• Pathophysiology:
o Metabolic Abnormalities: MR Spectroscopy / PET
o Perfusion Abnormalities: MRI / SPECT / PET / CT
• Future:
o New Image-Data Reconstructions
Robust Conventional Imaging Data: e.g. MR “Fingerprinting”
Raw Imaging Data: Collaboration with Imaging Industry
o New Imaging Acquisitions with Established Technologies: e.g. CT

REMIX AI Performance
Images to 256x256 matrix and processed with GoogLeNet convolutional network running on Caffe. 60 training epochs used.
Model creation with the first dataset (from Query 1, with 2,583 images) was 6 minutes and 19 seconds
Model creation for the second dataset (from Query 2, with 646 images), total processing took 97 seconds
Once image-classification models were created, batch image classifications performed at approximately 25 images per second.
