Brief Summary:
This study involves patients who are scheduled for standard care brachytherapy of focal tumours within the prostate, which is normally performed under standard 2-dimensional (2D) ultrasound guidance. The purpose of this study is the acquire power Doppler ultrasound while using a simple oscillator in physical contact with the end of a brachytherapy needle. The vibrations along the needle should be visible in the power Doppler ultrasound, helping to visualize the needle position within the anatomy.
