Dr. Brent Liu earned a Ph.D. degree from the UCLA Biomedical Physics Graduate Program and performed research as a Post Doctorate. During his graduate student research at UCLA from 1991 to 1996, Dr. Brent Liu had been involved in various medical image processing and informatics research projects. These include the analyses, design, implementation, and evaluation of an automatic image segmentation system based on object-oriented, knowledge base, and database-engineering principles applied to the image segmentation of bones in pediatric hand radiographs. Dr. Liu also researched and developed several image-processing applications such as image noise smoothing based on merging cluster of pixels with the aid of statistical information, removal of grid line artifacts in digitized X-ray images using Fourier Analysis filtering.

Upon graduation, Dr. Liu continued his post-doctorate research at UCLA from 1996 to 1999. During this time, Dr. Liu researched and designed a software module to capture Medical Imaging and Information data for the purposes of teaching, reviewing, and conferencing on a PACS workstation. Along with this software module, Dr. Liu contributed to the development of a suite of object-oriented class libraries to support methodological development of diagnostic PACS workstation functions and applications. These included the development of a software toolkit to convert current UCLA-proprietary PACS data into DICOM-compliant data files and the research of the use of adaptive and intelligent user interfaces and reading protocols in diagnostic PACS workstations.

From 1999 to 2002, he lead the implementation of a fully filmless PACS in a clinical setting within the Imaging Department of a high-profile community hospital (Saint John's Health Care, Santa Monica, CA). This included not only LAN PACS within the hospital but also WAN PACS to the physician's desktops. He was also involved with the planning and integration of other new information and imaging systems related to PACS, which include Nuclear Medicine and Radiation Oncology along with Radiology. He has served as a PACS consultant for another hospital to assist them in their integration of a fully filmless PACS. In 2002 to 2003, he also managed the implementation of a fully filmless PACS within a high-profile academic hospital (University of California Los Angeles Healthcare, Westwood, CA) that has multiple campus sites. His experience in PACS implementation is unique since he has had multiple contacts and interactions with various healthcare centers as well as the imaging industry. In addition, he brings hands-on practical knowledge of implementing different vendor PACS in both a high-profile community hospital and a large-scale academic hospital and the different experiences associated with both.

In 2003 he held an Honorary Lectureship at the Hong Kong Polytechnic University where he taught workshop courses in PACS Implementation, and Acceptance Testing Design/Development.

Current Projects:

1. Fault-Tolerant PACS Server 1999-Present
The project is to develop and test an affordable Fault-Tolerant PACS server using hardware redundancy, which runs uninterrupted with no downtime or data loss should any hardware component fail. I have been involved in the development of the clinical implementation and testing.

2. Medical Image Security 2002-Present
Medical Images security is an important issue when digital images and their pertinent patient information are transmitted across public networks. The project is to study the current data encryption technologies, and to design and develop an infrastructure of deploying the security standards in a hospital PACS environment.

3. Bone Age Assessment 2003-Present
The research project is to develop a large-scale digital hand atlas with a computer-assisted diagnostic (CAD) server supporting automated and Web-based bone age assessment for pediatric cases from age 0-18. Current bone age assessment is performed in the clinical environment using an outdated book containing images from a select group of children fifty years ago.

4. ASP Backup Archive for Clinical Images 2003-Present
With the development of PACS technology and an increasing demand by medical facilities to become filmless, there is a need for a fast and efficient method for providing data backup for disaster recovery and downtime scenarios. This project successfully implemented an Application Service Provider (ASP) solution for St. John's Health Center (SJHC), Santa Monica, CA using a fault-tolerant backup image archive at the Image Processing Informatics Lab (IPI) with a T1 connection. The project was extended as the ASP backup clinical image archive for the USC Healthcare Consultation Center II (HCC2) utilizing an Internet2 (I2) connection. HCC2 at USC/HSC is a fully digital imaging environment.

5. Data Storage Grid for Clinical Images 2004-Present
The Data Storage Grid represents the next generation of Fault-Tolerant Storage for backup and recovery of clinical images. Utilizing Grid Computing Technology as the basis for the architecture, the Data Storage Grid is also DICOM-compliant, which is the de facto standard for clinical image storage and distribution. The Data Storage Grid can be utilized for multi-institutional sites, enterprise-level healthcare, and large-scale clinical trials utilizing imaging.

6. PDA Applications in Medical Imaging 2004-Present
As real-time Radiology becomes more of a reality in a filmless environment, utilization of PACS workstations to perform specific tasks such as for diagnostic, review/consult, or quality assurance purposes become more and more crucial. However, in parallel to these specific tasks is the need to perform study management workflow. For this reason, the project goal was to develop a web application that allows the user to remotely send and view exams utilizing the DICOM standard and a mobile device such as the Personal Digital Assistant (PDA).

7. A Tracking and Biometric Verification System for a Secure Clinical Environment 2005-Present
Research project is to develop a novel system for a clinical environment using wireless technology and facial biometric technology to monitor and automatically identify staff and patients in order to streamline the patient workflow, protect against erroneous examinations and create a security zone to prevent and audit unauthorized access to patient healthcare data under the HIPAA mandate. The USC Department of Radiology, which just implemented a fully digital environment was an initial first clinical test environment.
