Embodiment Construction

[0061] In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and which show by way of illustration specific embodiments that may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments, and it is to be understood that logical, mechanical, and other changes may be made without departing from the scope of the embodiments. Accordingly, the following detailed description is not to be considered in a limiting sense.

[0062] Various embodiments of the present invention provide a system and method for locating needles based on light and shadows. The system includes a digital imaging and communications in medicine (DICOM) imaging device configured to acquire a plurality of images of a patient to identify a needle insertion point on the patient's body and a target point within the patient's body. The DICOM imaging device is configured to generate DICOM i...

Abstract

The embodiments of the present invention provide a system and method for light and shadow guided needle positioning. DICOM images of a patient are captured for identifying a point of insertion of a needle on the patient's body and a target point inside the patient's body. Needle coordinates are computed based on the captured DICOM images to position the mechanical arms. Light is projected at a particular angle on the needle to form shadows of the needle. Laser light beams are projected to form cross hair at the point of insertion. Images or videos of the point of insertion, shadow of the needle and the cross hair are captured and displayed on a monitoring unit. A virtual circle is projected on the displayed image and is aligned with the point of insertion, shadow of the needle and cross hair in order to insert the needle precisely.

Description

technical field [0001] The present invention relates generally to interventional medicine. In particular, the present invention relates to a needle positioning system and method for performing medical procedures. The present invention more specifically contemplates a system and method for guiding and positioning a needle from an insertion point on a patient's body toward a target point using the needle's shadow and light. Background technique [0002] In the field of interventional medicine, medical procedures for diagnostic or therapeutic purposes are performed by taking samples from a patient's body. For example, sample tissue from a specific internal organ of a patient's body is collected by inserting a medical device such as a needle. Because it is critical to insert the needle at the correct angle and to the correct depth, various imaging and localization techniques need to be used to guide the needle to the desired location within the body. These localization techni...
