Abstract

A system (100) may acquire (510) a first medical image of a region of interest of a subject in which one or more medical instruments (140) are present. The system (100) may determine (520) one or more regions of the first medical image corresponding to the one or more medical instruments (140). The system (100) may generate (530) a second medical image in which the one or more medical instruments (140) are absent using first medical image data of the first medical image outside the one or more regions and repair data inside the one or more regions. The system (100) may display (540) the second medical image. The system (100) may display one or more visual indicators indicating respective locations and/or directions of the one or more medical instruments (140) in the second medical image.

Description

System for catheter and shadow suppression in rendered 3D echocardiography Technical Field The present disclosure relates to a system for acquiring a medical image of a region of interest of a subject in which a medical instrument is present and generating a medical image of the region of interest in which the medical instrument is absent. Background During an interventional procedure, a clinician may navigate a medical instrument through a region of interest of a subject. For example, during heart surgery, a clinician may navigate medical instruments (e.g., catheters) through a subject's heart in order to ablate tissue, insert mitral clamps, close the left atrial appendage, deliver stents, remove thrombus, or analyze heart function, etc. Additionally, during interventional procedures, a medical imaging system (e.g., an ultrasound imaging system) may acquire medical images of the region of interest and the medical instrument and display the medical images to assist a clinician in navigating the medical instrument through the region of interest. In some cases, the display of the medical instrument in the medical image may obscure the medical image by occluding various potential anatomical features of the region of interest. Furthermore, the medical instrument may cause shadows in the medical image, which may also blur the medical image. Thus, the clinician may not be able to determine anatomical features that are obscured by the medical device or shadows of the medical device. Disclosure of Invention This summary introduces concepts that are described in more detail in the detailed description. It should not be used to identify essential features of the claimed subject matter, nor should it be used to limit the scope of the claimed subject matter. In one aspect, a system may include a memory configured to store instructions, and one or more processors configured to execute the instructions to obtain a first medical image of a region of interest of a subject in which a medical instrument is present, determine a region of the first medical image corresponding to the medical instrument, generate a second medical image in which the medical instrument is absent using first medical image data of the first medical image outside the region and repair data inside the region, and display the second medical image. In another aspect, a method may include acquiring a first medical image of a region of interest of a subject in which a medical instrument is present in the region of interest of the subject, determining a region of the first medical image corresponding to the medical instrument, generating a second medical image in which the medical instrument is absent using first medical image data of the first medical image outside the region and repair data inside the region, and displaying the second medical image. In yet another aspect, a non-transitory computer readable medium may store instructions that, when executed by the one or more processors, cause the one or more processors to acquire a first medical image of a region of interest of a subject in which a medical instrument is present in the subject, determine a region of the first medical image corresponding to the medical instrument, generate a second medical image in which the medical instrument is absent using first medical image data of the first medical image outside the region and repair data inside the region, and display the second medical image. Drawings FIG. 1 is an illustration of an example system for generating a medical image in which no medical instrument is present. FIG. 2 is a diagram of example components of one or more devices of FIG. 1. FIG. 3 is a diagram of example components of the medical imaging system of FIG. 1. FIG. 4 is a diagram of example components of the tracking system of FIG. 1. FIG. 5 is a flow chart of an example process for generating a medical image in which no medical instrument is present. Fig. 6A and 6B are diagrams of medical images. Fig. 7A and 7B are diagrams of medical images. Fig. 8 is a flowchart of an example process for generating a medical image in which no medical instrument is present or present based on whether the display of the medical instrument is switched on or switched off. Detailed Description As stated above, the display of the medical instrument and/or the shadows of the medical instrument in the medical image may obscure the medical image by occluding various potential anatomical features of the region of interest. Thus, the clinician may not be able to determine anatomical features that are obscured by the medical device or shadows of the medical device. In this way, the displayed medical image may not fully delineate the region of interest, which may inhibit the ability of the clinician to quickly and easily assess the entire region of interest during the interventional procedure. Some embodiments herein provide a system for generating medical images in which a medical instrument is not present in
