Dr. Michael A. Jacobs is a Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science. His research focuses on developing radiological methods for detecting, monitoring, and treating breast, brain, prostate and other cancers, with a particular focus on transferring research from the lab to the clinic.  He is Board Certified in Diagnostic Medical Physics by the American Board of Radiology.

Dr. Jacobs received his undergraduate degrees in mathematics and engineering science from the University of Michigan-Flint. He earned his Ph.D. in biomedical physics from Oakland University. He completed his fellowship in radiology at the Johns Hopkins University School of Medicine. Dr. Jacobs joined the Johns Hopkins faculty in 2003.

He serves on the National Board of the American College of Radiology Imaging Network (ACRIN) Radiomics committee. He is the Director of the Imaging Radiological Assessment Team (IRAT) of the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins. He is also one of the principal investigators on the Quantitative Imaging Network (QIN) U01 at Johns Hopkins University for developing novel methods for determining treatment response in clinical trials.

His work has been recognized with numerous awards and honors, including the 2012 Distinguished Investigator Awards from the Academy of Radiology Research, three Certificate of Merit Awards at the Radiological Society of North America, a bronze medal from the American Roentgen Ray Society and a National Research Service Awards Cancer Research Training Grant. He also was awarded multiple patents for his work related to radiological imaging. more

Advanced Treatment Response Prediction Using Clinical Parameters and Advanced Unsupervised Machine Learning: The Contribution Scattergram
Patent # US Patent 10,388,017 B2 | 08/20/2019

This patent provides methods for a method for detection of different ontologies using advanced unsupervised machine learning which will be used to visualize factors not visible to the human observer such as unknown characteristics between imaging datasets and other factors to provide insights into the structure of the data. We have termed this the Contribution Scattergram, For example, using radiological images, we can determine the relationship in dimension, structure, and “distance” between each parameter using advanced graph theoretic measures. This information can be used to determine if the changes within the images have occurred and these changes can be used for treatment response in different types od diseases. 

Multiparametric Non-linear dimension reduction methods for segmentation and classification of radiological images.
Patent # US Patent 9,256,966 | 02/09/2016

Visualization of anatomical structures is an important tool in medicine to differentiate normal tissue from pathological tissue using radiological imaging methods, which can generate large amounts of data for a radiologist to read.  Integrating these large data sets is difficult and time-consuming.  A new approach has used both supervised and unsupervised advanced machine learning techniques for visualizing and segmenting radiological data.  This study presents the application of a novel machine learning method based upon Non-Linear Dimensionality Reduction (NLDR) methods using an objective (unsupervised) computer algorithm implementing modified versions of Isomap, Local Linear Embedding (LEE), and Diffusion Maps.  We test the utility of these models using magnetic resonance imaging (MRI) data in patients.

Methods and systems for registration of radiological images
Patent # US Patent 9,008,462 | 04/14/2015

We developed a novel 3D registration method for application to radiological images. Typically, global motion seen in imaging is modeled by an affine transformation (rigid), while local motion and slice matching are estimated using some type of non-uniform resampling of the pixel intensities of the target image volume along a chosen reference plane. The reference plane is defined as the plane that the reference image volume was scanned, for example, axial, coronal, or sagittal.  The target plane can be any of anatomical planes obliterating the need for the reference and target scan planes to be the same.  Our method of registration is performed by searching for a reslicing angles and reslicing planes that maximizes similarity between the reference image volume and the resliced target image volume using novel multi-resolution wavelet transform. This wavelet transform provides estimated reslicing angles could lie between 0 and 360 degrees. By angular reslicing of the target image volume, the number of slices of the reference and target volumes will be the same and it deforms the target volume to morph it with the reference image volume.  Such a reslicing-based nonrigid registration of the radiological images according to this aspect of the present invention is a useful tool to match slices location and thickness, and 3D registration of the image or object slices.
