简要总结
The purpose of the study is to collect information on prostrate biopsy tissue for use in developing a method determining the difference in normal and cancerous prostrate tissue using the ClariCore System.
详细描述
The purpose of this study is to collect information on prostrate tissue biopsies using the ClariCore System. The ClariCore system is designed to improve how the tissue samples are being collected from the prostrate by using light sensors (fiber optics) that can see changes in the tissue. Researchers will study the data collected from the light sensor (optical readings) to develop a method (like a mathematical equation) that can be used to tell the difference between normal and cancerous prostrate tissue during the biopsy. What the researchers are hoping to learn from this study is if a light guided biopsy procedure can improve the accuracy of prostrate biopsy sampling.
