US 2023/0058905 A1 · ASSEMBLY COMPRISING AN OCT DEVICE FOR ASCERTAINING A 3D RECONSTRUCTION OF AN OBJECT REGION VOLUME, COMPUTER PROGRAM, AND COMPUTER-IMPLEMENTED METHOD FOR SAME

Abstract

The invention relates to an assembly (10) comprising an OCT device (20) for scanning an object region volume (22) arranged in an object region (18) using an OCT scanning beam (21), an object (24) with a section, which can be arranged in the object region (18) and which can be located in the object region volume (22) by means of the OCT device (20), in the object region volume (22), and a calculating unit (60) which is connected to the OCT device (20) and contains a computer program for ascertaining a 3D reconstruction of the object region volume (22) and for ascertaining the position of the section of the object (24) in the object region volume (22) by processing OCT scanning information obtained by scanning the object region volume (22) using the OCT device (20). According to the invention, the computer program has a calculation routine for ascertaining a target area (90) in the 3D reconstruction of the object region volume (22), said calculation routine determining a reference variable for the object (24) relative to the target area (90). The object (24) is designed as a surgical instrument which has a capillary with an opening for discharging a medium. The calculation routine of the computer program is used to ascertain an actual value of the volume of the medium discharged through the opening of the capillary in the target area by comparing data of the target area in the 3D reconstruction of the object region volume (22) and/or by comparing scanning information of the target area obtained by scanning the object region volume (22) using the OCT device (20) prior to and while discharging the medium. The invention also relates to a computer program and to a method for determining the volume of a medium discharged in an object region (18) through an opening by means of a surgical instrument with a capillary.

An arrangement comprising:

an OCT device for scanning an object region volume in an object region by means of an OCT scanning beam;
an item which has a section that is arrangeable in the object region volume and is localizable there by means of the OCT device;
and
a computer unit which is connected to the OCT device and which contains a computer program for determining a 3-D reconstruction of the object region volume and determining the relative position of the section of the item in the object region volume by processing OCT scanning information obtained by means of the OCT device by scanning the object region volume,
wherein the computer program has a computing routine for determining a target area in the 3-D reconstruction of the object region volume, said computing routine determining a guide variable for the item in relation to the target area, the item being in the form of a surgical instrument which has a capillary with an opening for the release of a medium and the computing routine of the computer program serving to determine an actual value of the volume of the medium released into the target area through the opening of the capillary by comparing data of the target area in the 3-D reconstruction of the object region volume and/or by comparing scanning information of the target area obtained by means of the OCT device by scanning the object region volume before and during the release of the medium.
