1. A digital microscope for a medical procedure on a patient, comprising:
image sensors (10) configured to capture a left-eye image and a right-eye image of an object and generate image data;
a lighting prism (20) arranged to be movable forward and backward along an optical path and adapted to split an incoming image of object into the left-eye image and the right-eye image, and direct the images to the image sensors such that respective images are formed on the image sensors;
pre-lenses (30) disposed in a pair at both sides behind the lighting prism (20), each pre-lens enlarging the image from the lighting prism with a predetermined magnification and transmitting the enlarged image to a corresponding one of the image sensors (10);
objective lenses (40) provided as two or more pairs arranged at angular intervals of 60 degrees, the objective lenses of each pair being selectively positionable on imaginary axes connecting the pair of pre-lenses (30) to the pair of image sensors (10), respectively, to adjust a magnification of the object image on the image sensors;
focus lenses (50) disposed behind the objective lenses (40), each focus lens moving forward and backward along a light path within a barrel to adjust focus of the object image on the corresponding image sensor;
displays (60) provided in a pair and implemented as digital displays in place of eyepieces, each display being configured to present, in real time, composed stereoscopic image derived from integrating the image data from the image sensors (10) with patient-specific medical information required for the diagnosis or procedure; and
an image processing unit (70) operatively coupled to the image sensors (10) and the displays (60), the image processing unit being configured to receive the image data from the image sensors, retrieve medical information of the patient from a server in a hospital via a communication connection, verify whether the image data corresponds to the same patient as the medical information, combine the image data with the medical information upon confirming a match to generate composed image data, and output stereoscopic composed image data including separate left-eye and right-eye components to the pair of displays (60) for three-dimensional visualization,
wherein
the lighting prism (20) comprises a first prism (21) and a second prism (22) having different refractive indexes, and the prisms are joined such that a rear surface of the first prism (21) and a front surface of the second prism (22) are flat and in intimate contact,
a front surface of the
first prism (21) has an angular structure with a protruding center region configured to separately receive the left-eye image and the right-eye image of the object, and
a rear surface of the second prism (22) has an angular structure with a convex center region configured to direct the left-eye image and the right-eye image, which enter through opposite sides of the front surface of the first prism (21), to the respective sensors (10),
wherein the image processing unit (70) consists of:
a communication unit (71) configured to connect to the server in the hospital and receive the medical information of the patient who is undergoing the diagnosis or procedure;
a matching processing unit (72) configured to compare the image data from the image sensors (10) with the medical information of the patient received via the communication unit (71), and to determine whether the image data and the medical information correspond to the same patient,
a composing processing unit (73) configure to create composed image data by combining the medical information of the patient, upon confirmation of a match by the matching processing unit (72), with the image data from the image sensors (10); and
an image creating unit (74) configured to perform a convergence angle adjustment on the composed image data to align image centers and adjust perceived depth, thereby generating left-eye image data and right-eye image data, and to output the left-eye image data and the right-eye image data to the pair of displays (60) for stereoscopic display.
