Experience

Software Engineer

Clario Medical Imaging, Seattle, WA 2007 - 2009

> Served as a core member in an agile team in all development phases

leading to the release of z3D, an FDA-cleared software system for MRI

breast cancer diagnosis.

. Reviewed and revised the requirements, specs, architecture, design, and

testing plans documentation.

. Implemented the DICOM network query/retrieve interface.

. Designed a fast algorithm for on-the-fly DICOM images structuring and

sorting.

. Designed a database scenario for imported and retrieved DICOM image

storage.

. Architected and implemented the motion correction module, applied

multiple optimization strategies to reduce its running time to sub

second enabling its real-time use in clinics.

. Tested multiple versions of z3D and fixed bugs.

> Managed image processing/analysis algorithms R&D; coordinated multi-site

clinical studies.

. Applied fuzzy patient matching to Multiple Patient Indexing (MPI),

achieved an accuracy of 98% on validation datasets.

. Designed a user interface for CTA and MRA 3D interactive visualization,

developed algorithms for blood vessel centerline computation and curved

planar reformation (CPR) display.

. Implemented a Web Service based DICOM Application Hosting Framework,

developed the SDK in multiple languages (C++, Python, and Matlab), with

Volume Rendering, Maximum Intensity Projection (MIP), and Multi-Planar

Reformation (MPR) applications as its sample plug-ins.

. Developed a diffusion-based method for chest X-ray and mammography

image enhancement.

. Developed a method to calculate the breast tumor malignancy probability

based on MRI.

. Designed a z-axis encoding PET-CT fusion image visualization method,

implemented a prototype for clinical evaluations.

Senior Fellow

University of Washington - MR Research Lab, Department of Radiology,

Seattle, WA 2006 - 2007

> Developed a software toolset to register fMRI and DTI data and used the

activation regions of fMRI to guide DTI fiber tracking for brain

connectivity study.

> Built image processing pipelines for automated segmentation and volume

measurement for brain MRI studies, allowing for mix-and-match use of

interchangeable tools from FSL, SPM, FreeSurfer, Phatasm, and MIPAV.

> Launched a wiki site to provide technical support on brain imaging

pipeline construction, operation, and maintenance.

> Designed and implemented a method for CT and MR image fusion for CSF leak

diagnosis and surgical planning.

> Developed an analysis tool for processing MR perfusion images for brain

tumor staging.

> Implemented a DICOM to Analyze/NIfTI file format converter on multiple

platforms: Windows, Linux, and Mac OS.

Research Assistant

University of Washington - Department of Bioengineering, Seattle, WA

2000 - 2005

> Invented a novel object modeling methodology combining discrete graph

cuts and continuous level sets methods in two steps.

> Developed a piece-wise registration approach to fusing CT and MR images

for cervical spine disease diagnosis.

> Performed ankle motion analysis from MRI and reduced the user interaction

time per case from 48 hours to less than 30 minutes using automated image

segmentation and registration.

> Developed Multi-Rigid, a software suite for volumetric data segmentation

and registration.

> Developed a C# GUI to guide clinical study workflow.

> Applied FEM and Spline based deformable image registration methods to

anatomic template and model matching, studies statistical shape

variations in normal and pathological populations.

> Designed a model storage scheme for a physiological modeling and

simulation system using MySQL and Java.

> Implemented an unsharp masking algorithm for image enhancement on MAP-CA,

a programmable media processor.

Research Assistant

Tsinghua University - Department of Electrical Engineering, Beijing, China

1997 - 2000

> Designed and developed a C++ library for DICOM image manipulation and

network communication.

> Architected and implemented a mini-PACS for the Radiology Department of

Beijing Electricity Hospital.

> Developed the control unit for an ultrasound Doppler blood flower

analyzer using TI DSP and FPGA.
