Latest Patents

Among his latest patents is the "Coherent Detection Ultrasound System." This ultrasound imaging system utilizes a short sinusoidal pulse burst for excitation and performs coherent detection of the reflected signal. This results in an improved signal-to-noise ratio, enhancing the clarity of ultrasound images. Additionally, the system preserves the polarity of the rate of change of parameters, mainly density, allowing for the reconstruction of a density versus distance signal through integration of the coherently detected signal. The system is equipped with components to calculate and apply all necessary phase corrections.

Another notable patent is the "Method for Measuring Incident Light in a Body Cavity." This invention features an obturator designed to measure incident light in remote sites, such as body cavities. It includes a treatment tubular member for delivering light and auxiliary tubular members for transmitting incident light to an external detector. The design allows for alignment with a cystoscope lens, facilitating phototherapy in body cavities, particularly in the treatment of superficial cancer in the bladder.
