FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine and can be used to measure the hemoglobin level in patient (38). Medical system (10) comprises a projector system, an imaging system, a hemoglobin module. Hemoglobin color scale (HbCS) (22) is projected into field of view (FOV) (42) of imaging system (12). HbCS (22) includes a plurality of blood color regions (26a-f). Each blood color region corresponds to a hemoglobin level and is colored to represent the color of blood at the corresponding hemoglobin level. Image of blood of patient (38), and projected HbCS is acquired using the imaging system.
EFFECT: group of inventions enables to measure the hemoglobin level in a patient objectively, non-invasively, without laboratory conditions due to the use of the projector system and the projection of the hemoglobin color scale in the field of view.
