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

Embodiments of the present invention provide a system and method for light and shadow guided needle positioning. A DICOM image of the patient is acquired to identify the insertion point of the needle on the patient's body and the target point within the patient's body. Needle coordinates were calculated based on the acquired DICOM images to position the robotic arm. Light is projected onto the needle at a specific angle to form a shadow of the needle. A laser beam is projected to form a reticle at the insertion point. An image or video of the insertion point, the shadow of the needle and the reticle is captured and displayed on a monitoring unit. An imaginary circle is projected onto the displayed image and is aligned with the insertion point, the needle's shadow and crosshairs for precise insertion of the needle.

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...
