CIALAB Follicular Lymphoma research to be published in the Computer Methods and Programs in Biomedicine Journal

The article entitled "Feature-Based Registration of Histopathology Images with Different Stains: An Application for Computerized Follicular Lymphoma Prognosis" has been accepted for publication in the Computer Methods and Programs in Biomedicine Journal. This study is a part of the computer-aided system being developed for the automated histopathological evaluation of Follicular Lymphoma, one of the most common type of lymphoid malignancy affecting more than fifty thousand people in the United States annually. The abstract of this study appears below:

Feature-Based Registration of Histopathology Images with Different Stains: An Application for Computerized Follicular Lymphoma Prognosis


Follicular lymphoma (FL) is the second most common type of non-Hodgkin’s lymphoma. Manual histological grading of FL is subject to remarkable interand intra-reader variations. A promising approach to grading is the development of a computer-assisted system that improves consistency and precision. Correlating information from adjacent slides with different stain types
requires establishing spatial correspondences between the digitized section pair through a precise nonrigid image registration. However, the dissimilar appearances of the different stain types challenges existing registration methods.
This study proposes a method for the automatic nonrigid registration of histological section images with different stain types. This method is based on matching high level features that are representative of small anatomical structures. This choice of feature provides a rich matching environment, but also results in a high mismatch probability. Matching confidence is increased
by establishing local groups of coherent features through geometric reasoning. The proposed method is validated on a set of FL images representing different disease stages. Statistical analysis demonstrates that with a proper feature set, the accuracy of automatic registration is comparable to manual registration.

CIALAB encouraging talented young minds with summer internships

CIALAB is pleased to introduce the three interns namely Tong Gan, Rosana Rodriguez Milanes and Michael Priddy working through summer’09. Rosana Rodriguez Milanes - I am a third year undergraduate student in Electronic Engineering from Universidad del Norte, Colombia. My experience as a volunteer foreign student in the Clinical Image Analysis Laboratory has been an edifying, gratifying and enriching. Being able to participate, to learn and to collaborate in the Clinical Image Analysis Laboratory during the past two weeks has allowed me to improve my analytical and interpretative skills in processing histopathological and MRI images. I have been able to learn about segmentation, region growing, splitting and merging algorithms development. I have also had the privilege of knowing and interacting with excellent engineers who have helped me improve my skills as a foreign student. I am grateful for the opportunity that the Ohio State University has given me to collaborate and to learn with...

Dr. Gurcan to present a tutorial at IEEE ICASSP 2010

Dr. Gurcan will present a tutorial at IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP) 2010 entitled “Biomedical Image Processing and Analysis Techniques.” ( http://www.icassp2010.org/Tutorial_03.asp) Biomedical image processing and analysis requires coordinated efforts of medical professionals, algorithmic and software engineers, and statisticians. Basic image processing techniques are frequently used in every aspect of the development from initial pre-processing techniques for noise reduction, to segmentation of lesions, to registration of lesions. Recent advances in hardware and software have made it possible to create digital scans of whole slides. These images are relatively large (100k x 100k) and in color, hence processing them present new challenges. Similarly, new computed tomography and magnetic resonance imaging scanners produce thousands of slices of images. The processing need for these images are enormous. Although biomedical image analy...

Meniscus research to be presented at 2009 OARSI World Congress on Osteoarthritis

CIALAB work detailing relationships between the meniscus and cartilage, and their implications in the development and progression of osteoarthritis, has been accepted for presentation at the 2009 OARSI World Congress on Osteoarthritis. The analysis was performed by Jeff Prescott, Furqan Haq PhD, Tom Best MD/PhD, Micheal Pennell PhD, Rebecca Jackson MD, and Metin Gurcan PhD. The full abstract appears below. Purpose : To determine associations between meniscus volume and knee cartilage morphological measurements in subjects with osteoarthritis (OA). Methods : All data was obtained from the Osteoarthritis Initiative’s (OAI) public use dataset (www.oai.ucsf.edu). A sample of progression subjects produced by the OAI was used for the study (Subgroup B, release 0.B.2). Out of the 160 subjects in the sample, two had no discernable meniscus and were excluded, leaving 158 subjects in the analysis. The current study focused on the right knee, as this was the only knee for which cartilage measur...
