Abstract

abstract of the disclosure the present disclosure relates to apparatus, systems, compositions, and methods for analyzing a sample containing particles. a particle imaging system or analyzer can include a flowcell through which a urine sample containing particles is caused to flow, and a high optical resolution imaging device which captures images for image analysis. a contrast pattern for autofocusing is provided on the flowcell. the image processor assesses focus accuracy from pixel data contrast. a positioning motor moves the microscope and/or flowcell along the optical axis for autofocusing on the contrast pattern target. the processor then displaces microscope and flowcell by a known distance between the contrast pattern and the sample stream, thus focusing on the sample stream. cell or particle images are collected from that position until autofocus is reinitiated, periodically, by input signal, or when detecting temperature changes or focus inaccuracy in the image data. tradução do resumo resumo patente de invenção "célula de fluxo, fluido envoltório e sistemas de foco automático e métodos para análise de partículas em amostras de urina" a presente revelação se refere a aparelho, sistemas, composições e métodos para analisar uma amostra que contém partículas. um sistema de imageamento ou analisador de partículas pode incluir uma célula de fluxo através da qual uma amostra de urina que contém partículas é induzida a fluir, e um dispositivo de imageamento de alta resolução óptica que captura imagens para a análise de imagem. um padrão de contraste para a focalização automática é fornecido na célula de fluxo. o processador de imagem avalia a exatidão de foco a partir do contraste de dados de pixel. um motor de posicionamento move o microscópio e/ou célula de fluxo ao longo do eixo geométrico óptico para focalização automática no alvo de padrão de contraste. o processador, então, desloca o microscópio e a célula de fluxo por uma distância conhecida entre o padrão de contraste e a corrente de amostra, focalizando, assim, a corrente de amostra. as imagens de célula ou partícula são coletadas a partir daquela posição até que o foco automático seja reiniciado, periodicamente, por sinal de entrada, ou quando se detecta mudanças de temperatura ou inexatidão de foco nos dados de imagem.
