## Abstract

Ultrasound (US) is a widely popular imaging technique for the diagnosis of tumors and associated soft tissue pathology. Traditionally, excised tumor masses are manually sliced for microscopic examination, which is a resource-intensive, time-consuming process, and prone to human error. The proposed work addresses these challenges by developing a cost-effective US gantry system integrated with a deep learning algorithm to automate the tissue slice selection process. This system scans the entire tumor and by integrating a deep learning algorithm predicts the optimal slice to assist its preparation for microscopic analysis. Automating this process reduces the time and resources required while minimizing the risk of human error. Optimal tissue slice reduces sampling associated uncertainty in diagnosis and treatment planning. Thereby determining tumor grade and type, and helping to reduce the treatment risks. The initial development focused on a linear US gantry that moves in one direction to acquire B-mode images. However, this design is limited, as it cannot fully capture the tumor’s structural complexity. In order to overcome this, we developed an angular US gantry that can maneuver along multiple angles, acquiring a broader range of images for comprehensive geometric analysis. The angular gantry demonstrated significant improvement, achieving 98% accuracy in selecting the optimal tissue slice.
