Abstract

A system and method for locating the position of a target in a patient during treatment is disclosed. The system is configured to draw horizontal scale markers on the top of the acquired image and on the side of the probe. The user selects the target such as a point or an area on the image. The system is configured to mark the selected target on the horizontal scale on the image. The user finds the positions corresponding to the marked points on the horizontal scale on the side of the probe. When the user moves the probe horizontally to align the target and center line of the probe, the system tracks the selected point or area using cross-correlation algorithm. The system then indicates the changed position of the target on the probe. The system and method provide accurate position information of a target for biopsy, operation, or training purposes.

SYSTEM AND METHOD FOR LOCATING HORIZONTAL POSITION OF A TARGET IN A TREATMENT

BACKGROUND

The invention relates to a system and method for locating horizontal position of a target in a patient during treatment. During surgical treatment of tumors biopsy with ultrasound guidance is a common procedure, with or without a biopsy kit. The operator performing the biopsy may guess the horizontal position of the target and the shortest path to insert the needle, a technique which may improve with by experience. If a biopsy kit is used, the operator will align the target and centerline on the image. This process usually needs two people, one person familiar with ultrasound imaging to watch the ultrasound image and give moving instructions to the other person who will operate the biopsy kit. If this method is operated by a single person, he has to alternate between the probe and the ultrasound image in turns. Further, the target may be move and leave the target location. This method is usually inaccurate and requires more time to locate the exact position. Another situation in which a user is required to know the exact position of a target in a patient is when there is need for scanning with another imaging modality. Thus, there is a need for a system and method for providing accurate information on the position of the target for purposes of biopsy, for operative procedure, or training.

BRIEF DESCRIPTION OF DRAWINGS

The invention discloses system and method for locating horizontal position of a target in a treatment, wherein:

FIG. 1 shows a flowchart of the method for locating horizontal position of a target in a treatment.

DETAILED DESCRIPTION

The invention proposes a system and method for locating the position of a target in a patient during treatment. The system is configured to display a same horizontal scale both on the top of the acquired image and the side of the probe. The starting point is the center of the probe and the ending point is the left and right border of the probe. The system could display the position and range of the selected target such as tumor on the image using one or more indicators. The user could identify the corresponding position and range on the horizontal scale of the probe based on the patient coordinates.

The method for locating the position of a target in a treatment uses the following steps as shown in FIG. 1. In Step 1, the system is configured to draw horizontal scale markers on the top of the acquired image and on the side of the probe. The horizontal scale markers should match the same distance on the probe. In the following Step 2, the user selects the target such as a point or an area on the image. In Step 3, the system is configured to mark the selected target on the horizontal scale on the image. A single point is used to indicate a selected point, while three points are used to indicate a selected area, the leftmost point, the rightmost point, and the center point of the area. In Step 4, the user finds the p...
