Laser light is emitted from a laser into a scattering layer. An ultrasound signal is emitted into a sample. A signal is generated with a light detector in response to a measurement beam of laser light exiting the light scattering layer into the light detector. At least a portion of the measurement beam formed between the laser and the light detector is wavelength-shifted by the ultrasound signal subsequent to the ultrasound signal propagating through the sample.

The image acquisition medical device includes a flexible body portion that extends in an axial direction; an image sensor that is disposed in the body portion and that is configured to acquire an image of a hollow organ; and a contrast unit that protrudes toward a distal end side of the body portion and that makes an orientation of a distal end portion of the body portion visually recognizable in an angiographic image. Relative positions of the image sensor and the contrast unit in an axial rotation direction are fixed.

The invention relates to a medical optical system. The medical optical system comprises: —a microendoscope (3) for capturing histological images, each of which displays a microscopic tissue section (16) of a macroscopic tissue region (15) with a tumor (23); and—a classification device (31) for classifying the macroscopic tissue sections (16) displayed in the histological images as at least one respective tissue section that represents the tumor (23) or a tissue section that represents healthy tissue and for outputting a classification result for each classified microscopic tissue section (16). The medical optical system additionally comprises a combination device (37) which generates a macroscopic classification image (43) by combining the classification results, said classification image representing the location of the tumor (23) in the macroscopic tissue region (15).
