MEDICAL IMAGING SYSTEM, ILLUMINATION DEVICE, AND METHOD
First Claim
1. A medical imaging system comprising:
- an illumination device comprising;
a first light source configured to emit first light having a wavelength range;
a second light source configured to emit second light having at least one predetermined wavelength band, wherein the at least one predetermined wavelength band is within the wavelength range; and
a dichroic mirror configured to attenuate a portion of the wavelength range corresponding to the at least one predetermined wavelength band and to multiplex the second light with the first light such that the portion of the wavelength range of the first light is attenuated, wherein light multiplexed by the dichroic mirror is emitted from the illumination device along an optical axis and irradiates an observation site; and
a medical imaging device comprising at least one image sensor configured to receive light from the observation site.

Abstract
According to some aspects, a medical imaging system is provided. The medical imaging system includes an illumination device and a medical imaging device. The illumination device includes a first light source configured to emit first light having a wavelength range. The illumination device further includes a second light source configured to emit second light having at least one predetermined wavelength band. The at least one predetermined wavelength band is within the wavelength range. The illumination device further includes a dichroic mirror configured to attenuate a portion of the wavelength range corresponding to the at least one predetermined wavelength band and to multiplex the second light with the first light such that the portion of the wavelength range of the first light is attenuated. The light multiplexed by the dichroic mirror is emitted from the illumination device along an optical axis and irradiates an observation site. The medical imaging device includes at least one sensor configured to receive light from the observation site.
