Abstract
By adding perspective information in addition to binocular parallax, the invention provides a three-dimensional medical imaging apparatus that allows surgery to be performed with a more natural three-dimensional view, similar to that achieved with the naked eye. The three-dimensional medical imaging apparatus includes an image-acquisition optical system and an imaging device for acquiring three-dimensional images of a subject. The image-acquisition optical system includes an objective optical system for forming an image of the subject at an image-forming plane, and an entrance pupil position of the image-acquisition optical system is disposed between the objective optical system and the subject.
Claims3
A three-dimensional medical imaging apparatus for acquiring three-dimensional images of a subject, comprising:
- an image-acquisition optical system;
- and
- an imaging device,
- wherein the image-acquisition optical system includes an objective optical system for forming an image of the subject at an image-forming plane and a relay optical system for conveying the image formed by the objective optical system to the vicinity of an image-acquisition surface of the imaging device;
- and
- a conjugate position of a pupil position set in the relay optical system is disposed towards the object side of the objective optical system.
