Quantitative Image Processing Center (QUIPC)

When 3-D Imaging Alone Is Not Enough...

Chaired by Dr. Ronald L. Arenson, M.D. Professor of Radiology and a highly skilled team of collaborators, The Quantitative Image Processing Center (QUIPC), formerly known as the 3D Imaging and Processing Lab is dedicated to delivering clinically relevant and advanced processing of visualization of medical CT and MR images, largely through PACS, in order to aid in the diagnosis and pre-surgical planning of patients.

By using the rapid retrieval of digital medical records, reports and imaging of PACS, Dr. Arenson and his team are steering QUIPC to provide some of the most comprehensive and accurate medical information possible to the physician, assuring that the patient receives the best care.

Research Focus

Quantitative Image Processing, picture archiving and communication systems (PACS)

Research Directions

The Quantitative Image Processing Center (QUIPC) provides analytic and research services for clinical trials, assessing new therapies and using imaging as a selection tool or as an endpoint. These services include:

  • Consultation on the design and implementation of clinical trials  involving imaging
  • Quality assurance and centralized readings and quantitative measurements of CT, MRI and PET scans

Services include expert readings by senior radiologists, qualitative and quantitative assessment of lesion volume and response over time, with capabilities for high resolution film digitizing, volumetric analysis on workstations.

Those interested in further information regarding these research and analytic services, please contact UCSF QUIPC.


The Workstations

  • GE Advantage Windows running 5.0 software and equipped with complete 3D analysis software includes Volume Viewer, Navigator, Vessel Analysis, CV Flow, Mass Analysis, CT Perfusion, Smart Score, Cardiac IQ (including function), Colonography, Advanced Lung Analysis, CT Perfusion, and Data Export.
  • TeraRecon Aquarius workstations utilize TeraRecon's VolumePro 3D rendering engine to manage large slice and multi-phase CT-MR datasets. Advanced clinical functionality includes cardiac CT and vascular analysis, endovascular 3D stent planning tools, time-density analysis for contrast perfusion of the brain, lung nodule tracking & analysis, and flythrough auto navigation for CT Colonography.
  • TeraRecon AquariusNET Server will provide real-time interactive diagnostic 3D to remote radiologists and clinicians by streaming images using standard PCs throughout the hospital. Radiologists use AquariusNET thin client for fast 3D problem solving, interactive MIPs and MPRs, and for capturing representative images and clips for physicians.
  • Custom UNIX workstation for MR spectroscopy processing.
  • Ziosoft thin client for post-processing.
