Title: Innovations of Stephen M Grenon
Introduction
Stephen M Grenon is an accomplished inventor based in Manchester, NH (US). He has made significant contributions to the field of ultrasound technology, holding two patents that showcase his innovative approach to medical imaging.
Latest Patents
One of his latest patents is titled "Method for maintaining a constant velocity to color map in an ultrasound." This invention employs pulsed Doppler ultrasound signals to color image blood and tissue movement velocities in a body. The method initially images a movement with a transmitted ultrasound signal that manifests a current signal transmission frequency value and a current pulse repetition frequency (PRF) value. Those values exhibit a determined ratio R to each other. In response to an indication by the user that movement is to be imaged at a new depth, the method alters the current transmission frequency to a new frequency to provide improved signal back-scatter from movement at the new depth. The current PRF is adjusted automatically to a new PRF value, ensuring that the mapping of movement velocity values to colors is maintained, notwithstanding the use of a new transmission frequency.
Another notable patent is the "Phased array ultrasound imaging system with dynamic elevation focusing." This system includes a transducer with multiple transducer elements disposed along a lateral axis. The transducer has an aperture with an elevation dimension that increases between the midpoint of the aperture along the lateral axis and the ends of the aperture. When used in an ultrasound imaging system, the active receive aperture dynamically increases in size during reception of ultrasound energy from progressively increasing depths, thereby providing dynamic elevation focusing.
