An embodiment of the present invention relates to an apparatus and method for excision surgery guide for displaying a safety margin line around a lesion in an object and providing a guide for lesion resection.

When a tumor develops in the pelvis, arm, or leg bone, the tumor must be removed from the tumor with a safety margin.

Conventional methods for finding the point at which the safety margin from the tumor has disappeared include continuous imaging of the surgical site using a radiographic imaging device (e.g., C-Arm, x-ray) in the operating room, tracking the tumor, Respectively.

However, due to the continued use of radiographic imaging devices, both physicians and patients may be exposed to large amounts of radiation.

An embodiment of the present invention provides a method for creating a safety margin line around a lesion in a volume image generated by at least including a lesion and aligning the safety margin line with an object by matching the volume image with an object, The object is to guide the optimal site for eliminating lesions by displaying on the object.

An embodiment of the present invention forms a three-dimensional safety margin line around the lesion and displays at least some of the safety margin lines in two dimensions when the lesion is extracted, thereby making the safety margin line in the object more intuitive To be able to recognize it.

A resection surgical guide apparatus according to an embodiment of the present invention includes a scan unit for generating a volume image including at least a lesion, a forming unit for forming a safety margin line around the lesion in the volume image, and a processor for matching the volume image to an object and displaying the safety margin line on the object.

The processor may match the volume image to the object so that the lesion in the object matches the lesion in the volume image.

The forming unit may form, as the safety margin line, a contour having a predetermined separation distance based on the lesion.

The processor may display at least some of the contours two-dimensionally upon extraction of the lesion.

The resection operation guide apparatus may further include a marking unit for marking a resection portion on the object based on a safety margin line displayed on the object.

The forming portion 103 may form a safety margin line around the lesion in the volume image. At this time, the forming part 103 can form a three-dimensional safety margin line, and a contour having a set distance (for example, 1 to 2 cm) on the basis of the lesion, Can be formed as a margin line.

As another example, the forming section 103 may be provided with an environment for removing lesions other than lesions, by minimizing the removal of lesions by adjusting the spacing distance to form a safety margin line of the minimum size including the lesion Let's do it.

The processor 105 matches the volume image to an object, implements the volume image as an augmented reality, displays the safety margin line on the object, can do. At this time, the processor 105 may check the volume image on the object, and perform the matching by causing the volume image to overlap the object. In the present specification, such a matching process is defined as an augmented reality. In addition, the processor 105 may match the volume image to the object so that the lesion in the object matches the lesion in the volume image. In implementing the augmented reality, the processor 105 increases the accuracy of the augmented reality by making the reference marker a multi-face, and allows the lesion to be observed in any direction.

On the other hand, when extracting the lesion, the processor 105 displays the safety marginal line in the object more intuitively by displaying at least a part of the contour in two dimensions.
