Project Title: Designing A Myoelectric Hand Prosthesis 

Description: 

In this project, I focused on the design and development of a myoelectric hand prosthesis, specifically a right-hand prosthesis for a patient with unilateral amputation. The study addressed the complex challenge of technically substituting the human hand by integrating principles from functional anatomy, biomechanics, mechanical engineering, and electronics.

Key Features:

• Anatomical and Biomechanical Study: A thorough analysis of the human hand's essential characteristics, including joint mobility, grip strength, and prehension types, was conducted to inform the prosthetic design. This involved direct anthropometric measurements of a patient's hand to determine critical dimensions.

• Kinematic and Dynamic Calculation: The project involved calculating angular velocities and rotations for finger movements, essential for designing the prosthesis's functional range.

• Mechanism Design and Optimization: An antiparallelogram kinematic mechanism was chosen for synchronized finger movements, specifically for a three-jaw chuck grip. The optimal mechanism configuration was selected to ensure functional and aesthetic movement.

• Component Selection: A miniature DC motor (Portescap 16G88) was selected, coupled with a planetary gearbox (BA16) and an additional worm gear reducer, to meet the specific requirements for torque, speed, and compact size. This configuration offers self-locking capabilities, crucial for maintaining finger position without continuous power.

• Integration and Ergonomics: The design prioritized integrating all components within a compact form factor, compatible with the patient's anthropometric dimensions, aiming for a total weight close to that of the natural hand.

Project Title: Identifying Pulmonary Lesions from Thoracic CT Scans Using Classical Image Processing

Description:

This project focused on detecting lung lesions from axial CT scans by implementing classical image processing techniques on a publicly available Kaggle dataset containing of thoracic CT images (normal and with different types of lung cancer). The project aimed to isolate and visualize pulmonary nodules through contrast enhancement, binarization, and morphological operations.

The goal was to evaluate the performance of non-AI-based methods for medical image segmentation, particularly in conditions where lesions were clearly delimited from surrounding anatomical structures. The study highlighted both the potential and the limitations of classical approaches, showing their reliance on the clarity of lesion boundaries and local contrast.

Key Features:

• Stepwise image preprocessing: piecewise linear contrast adjustment, contrast stretching, clipping, binarization

• Morphological processing: erosion, dilation, interior contour extraction, and morphological gradient

• Identification and segmentation of nodules using Python and OpenCV-based techniques

• Comparison of segmentation effectiveness across different preprocessing strategies
