Senior Member Technical Staff

Siemens Medical Solutions

May 2005 - May 2009

• Worked on detection of nodules in low resolution (large slice thickness) in Lung Computed Tomography images
• Designed several features to characterize pulmonary embolism (PE) and PE-look-alikes (looks similar to PE but are actually not) in CT pulmonary angiography (CTPA).
• Designed several feature extraction techniques for lesion (nodule) detection in Chest X-ray for improvement in an existing CAD prototype.
• Pioneered and designed image processing algorithms for automatic detection of different body parts in Computed Tomography (CT) images.
• Developed and designed an automatic technique for detection of intracranial hemorrhage and acute intracranial hemorrhage in various anatomical locations in brain Computed Tomography (CT) for trauma cases where no contrast can be applied and the CT has large slice thickness.

• Pioneered, motivated, supervised and managed invention disclosures amongst team members within the Business Unit of the organization as part of Innovation drive.

Scientist - D

Defense Research Development Organization

November 2002 - February 2004

• • Implemented designing, analysis and development of some new and novel algorithms for radar signal and image processing.
o Radar Target Identification and Classification
 A generic algorithm is developed to identify radar targets. A high fidelity simulation of the signal samples produced by the radar targets has been created. The output of the simulation is designed for combination with the output of clutter and signal processor simulation so that target detection in clutter can be examined. The algorithm is based on wavelet transform. Characteristic features of the radar echo signal is extracted by using wavelet frames. The features so extracted are classified employing a feed-forward neural network.
o Enhancement of Synthetic Aperture Radar Image
