METHOD, SYSTEM AND APPARATUS FOR THE DETECTION, CHARACTERIZATION AND CLASSIFICATION OF PARTICLES

摘要

Provided herein is a method to detect, characterize and classify a particle comprising: controlling a light source and an ultrasound transducer to irradiate the particle with light and an ultrasound pulse; determining a feature associated with the particle by processing ultrasound data resulting from the particle being irradiated; and comparing the feature to a reference to determine at least one property of the particle. According to some non-limiting implementations, the feature comprises a power spectrum of the particle. According to some non-limiting implementations, the ultrasound data is processed to determine characteristics in a range of about 100 MHz to about 1000 MHz of the power spectrum. According to some non-limiting implementations, the ultrasound pulse is in a range of about 100 MHz to about 1000 MHz. A computing device to detect, characterize and classify a particle is also provided.
