Latest Patents

Ruida Cheng holds a patent titled "Detection of prostate cancer in multi-parametric MRI using random forest with instance weighting and MR prostate segmentation by deep learning with holistically-nested networks." This patent presents a cutting-edge prostate computer-aided diagnosis (CAD) system that employs a Random Forest classifier to detect prostate cancer. The system classifies individual pixels within the prostate as potential cancer sites by utilizing a combination of spatial, intensity, and texture features extracted from multiple MRI sequences. A notable aspect of this patent includes the consideration of instance-level weighting during Random Forest training to ensure equitable treatment of both small and large cancerous lesions, as well as varying prostate backgrounds.

Additionally, the patent discloses approaches such as an AutoContext pipeline designed to optimize the analysis of sequence-specific patterns, alongside innovative methods for the automatic segmentation of the prostate in MRI scans. These methods incorporate both patch-based and holistic deep learning techniques for precise contour detection. A unique feature of this invention is the integration of holistically nested networks (HNNs), which autonomously learn hierarchical representations that enhance the accuracy of prostate boundary detection.
