Abstract
Systems and methods related to the location of target regions in imaging applications are generally described. Certain embodiments relate to devices and/or methods for image-guided identification of suitable regions at which to insert needles, catheters, and the like. Such systems and methods can be used in association with a variety of imaging technologies, including ultrasound imaging. In certain embodiments, the systems and methods described herein can be used in association with hand-held ultrasound imaging devices.
Core Innovation
The invention provides systems and methods for the image-guided identification of suitable regions for inserting needles, catheters, and similar instruments, specifically in the context of imaging applications such as ultrasound. The device is comprised of a housing with an imaging unit and a working side designed to be adjacent to the target being imaged. A key feature is the integration of a marking unit, which is capable of producing a mark on the target to be imaged, and, in some embodiments, a template and/or alignment indicators that facilitate precise localization of the target region based on the output of the imaging unit.
One main problem addressed by this invention arises from the limitations of current ultrasound devices: they lack a mechanism to accurately mark the target location on the skin while imaging is ongoing. Standard methods involve removing the transducer and manually marking the skin, which can produce errors in needle placement. Moreover, existing needle guide systems are typically restrictive, requiring fixed insertion angles and providing guides on only one side of the device, making precise alignment with underlying anatomy difficult, especially when the intended insertion point is covered by the device during imaging.
The core innovation enhances accuracy and reliability during procedures requiring image-guided access. The subject invention introduces several means of marking (including a laser, mechanical indentation, lancing, ink deposition, or visible reflection) that can be activated by a button or trigger while the device is in place, enabling a mark to be made within the boundaries of the imaging device, the output display, or the imaging plane. Further, with the addition of alignment indicators and templates, clinicians can triangulate and replicate precise target sites even after the device is removed, supporting a variety of procedures across multiple imaging modalities.
Claims Coverage
There are two independent claims, each detailing inventive features related to target region marking and identification in imaging applications.
Imaging device with integrated working side, output display, actuator, and marking unit
The device comprises: - A housing that includes an imaging unit and a working side, where the working side features a first portion for placement against the target surface and a recessed portion that forms a gap with the target surface. - An output display that covers at least part of the housing surface opposite the working side. - An actuator positioned on the surface of the housing opposite the recessed portion. - A marking unit located on the recessed portion, configured to produce a mark on the target’s surface only when the actuator is activated while the first portion of the working side is situated on the target surface.
Method for positioning, imaging, and marking a target region using a recessed portion on an imaging device
The method involves: 1. Positioning a first portion of the working side of an imaging device housing on a surface adjacent to the external surface of a target to be imaged. 2. Forming a gap between a recessed portion of the working side and the target surface. 3. Generating image data of the target with the imaging unit. 4. Displaying the image on an output display covering at least a portion of the surface of the housing opposite the working side. 5. Activating a marking unit, disposed on the recessed portion, to produce a mark on the target surface while the first portion is on the surface adjacent to the external target surface.
The independent claims cover an imaging device and a method, both focused on marking a target region with enhanced accuracy while the imaging device remains in place. The inventive features encompass integration of a specialized working side, output display, actuated marking unit on a recessed portion, and corresponding procedural steps that achieve precise localization of target regions in image-guided interventions.
Stated Advantages
Allows for more accurate and precise identification and marking of points of interest, such as insertion points for injection procedures and other medical procedures.
Addresses limitations of current ultrasound devices by enabling accurate skin marking relative to underlying anatomy while the imaging device is in place.
Provides flexibility with multiple types of marking units (laser, mechanical indentation, lancing, ink-based marker), improving adaptability to different clinical preferences and situations.
Reduces localization errors caused by devices or guides that only allow marking or guidance on one side, or require fixed needle insertion angles.
Documented Applications
Image-guided identification of suitable regions for inserting needles, catheters, and similar instruments.
Use in association with a variety of imaging technologies, including ultrasound imaging.
Use in association with hand-held ultrasound imaging devices.
Facilitates procedures such as central venous line placement and various spinal anesthesia procedures.
