Abstract

método para localizar região de interesse em tecido, dispositivo, aparelho e meio de armazenamento. trata-se de um método para localizar uma região de interesse de tecido, um dispositivo, um aparelho e um meio de armazenamento. o método compreende: adquirir, por meio de uma sonda ultrassônica, um sinal de eco ultrassônico de uma região de detecção (s101); identificar, de acordo com um valor de parâmetro ultrassônico do sinal de eco ultrassônico, uma região de interferência e uma região de interesse na região de detecção (s102); determinar se a região de interferência tem um tamanho que atende uma condição predeterminada; e, se tiver, remover um sinal de interferência correspondente à região de interferência do sinal de eco ultrassônico (s103). dessa forma, a invenção elimina, se uma região de interferência for pequena, um sinal de interferência localizado adaptativamente uma região de interesse e realiza, com o uso de um sinal que tem o sinal de interferência eliminado, processamento de informações e extração de informações relacionados à região de interesse, aumentando, assim, a exatidão e a robustez da análise de sinal relacionada às regiões de interesse e aumentando a exatidão dos resultados de detecção.
