An illustrative system includes an image sensor comprising a first pixel, a second pixel, a third pixel, and a fourth pixel. The system further includes a pixel-level broadband infrared cutoff filter that covers the second pixel and that is configured to prevent the second pixel from collecting infrared light having wavelengths included in a first range of wavelengths. The first, third, and fourth pixels are not covered by pixel-level broadband infrared cutoff filters configured to prevent the first, third, and fourth pixels from collecting infrared light having wavelengths included in the first range of wavelengths.

Medical imaging systems and methods

An exemplary medical imaging system includes a visible light illumination system configured to selectively emit one of a first visible light biased to a first wavelength and a second visible light biased to a second wavelength, a fluorescence excitation illumination system configured to selectively emit one of a first fluorescence excitation illumination having a third wavelength and a second fluorescence excitation illumination having a fourth wavelength, and an illumination source control unit configured to selectively direct the visible light illumination system to emit the second visible light and the fluorescence excitation illumination system to emit the first fluorescence excitation illumination for use with a first fluorescence imaging agent, and selectively direct the visible light illumination system to emit the first visible light and the fluorescence excitation illumination system to emit the second fluorescence excitation illumination for use with a second fluorescence imaging agent.

Medical imaging systems and methods that facilitate use of different fluorescence imaging agents

A two-by-two pixel array within an image sensor includes a first pixel, a second pixel, a third pixel, and a fourth pixel. A red filter covers the first pixel, a first blue filter covers the second pixel, a second blue filter covers the third pixel, and a green filter covers the fourth pixel. The red filter is configured to allow the first pixel to collect a red component of visible light and prevent the first pixel from collecting blue and green components of the visible light. The first and second blue filters are configured to allow the second and third pixels to each collect the blue component and prevent the second and third pixels from collecting the red and green components. The green filter is configured to allow the fourth pixel to collect the green component and prevent the fourth pixel from collecting the red and blue components.
