A processor acquires a radiographic image including a human body and a surgical tool image which indicates a surgical tool and is acquired by a method other than radiography. The processor combines the surgical tool image with the radiographic image to generate a training image for training a discriminator that discriminates a region of the surgical tool in a target image in a case in which the target image is input.

A gauze detection system is provided that is capable of effectively detecting a gauze pad in the patient's body during surgery without applying special processing to the gauze pad. A gauze detection system 100, includes: an image input section 1 to input a taken image of an operative field; a determination section 2 to determine whether a determination target region contains a feature of a gauze image by image processing, the region having a predetermined size in an input image; and a determination result output section 3 to report detection of a gauze pad in the input image in a case of the determination target region being determined by the determination section 2 to contain the feature of the gauze image.

A surgical material, such as gauze, includes a feature that increases the magnetic permeability of the surgical material. The surgical material incorporates one or more elements with high magnitude of magnetic permeability within the surgical material. In an embodiment, the one or more elements are coupled to a strip of material such as in the form of beads.

A surgical pad having a head part including an intermediate layer including an X-ray detectable material for use in surgical operations, particularly in brain and spinal cord operations. In the surgical pad, the intermediate layer is provided between layers, which are produced from 100% cotton and have a geometric shape that is manually formed.

An improved surgical sponge having a contrast agent, such as bismuth beads, secured to the sponge material in a unique pattern of a type not found in nature or in human anatomy. The unique pattern is preferably spaced dots or circles having various sizes and spacing, potentially arranged in a matrix of rows and columns. The desired unique pattern is arranged such that the dots or other non-natural shapes are large enough to remain visible, while small enough to avoid adversely affecting the pliability and absorption of the sponge.

Implementations generally relate to surgical scene assessment based on computer vision. In some implementations, a method includes receiving a first image frame of a plurality of image frames associated with a surgical scene. The method further includes detecting one or more objects in the first image frame. The method further includes determining one or more positions corresponding to the one or more objects. The method further includes tracking each position of the one or more objects in other image frames of the plurality of image frames.
