Target region identification for imaging applications
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.
1. A device, comprising:
a housing comprising:
an imaging unit; and
a working side including a first portion configured to be placed on a surface adjacent a target that is to be imaged and a recessed portion configured to form a gap between the recessed portion and the surface of the target when the first portion is disposed on the surface of the target;
an output display covering at least a portion of a surface of the housing opposite the working side;
an actuator on the surface of the housing opposite the recessed portion; and
a marking unit disposed on the recessed portion of the housing and configured to produce a mark on the surface of the target to be imaged within boundaries of a periphery of the output display only when the actuator is activated while the first portion is disposed on the surface of the target.
2. The device of claim 1 , wherein the actuator comprises a button.
3. The device of claim 1 , wherein the imaging unit comprises an ultrasound transducer.
4. The device of claim 1 , wherein the marking unit comprises a laser.
5. The device of claim 4 , wherein the laser is configured to produce a discoloration on the target that is to be imaged.
6. The device of claim 4 , wherein the laser is configured to produce a reflection of electromagnetic radiation on the target that is to be imaged.
7. The device of claim 1 , wherein the marking unit comprises a mechanical indentation unit.
8. The device of claim 1 , wherein the marking unit comprises a lancing unit.
9. The device of claim 8 , wherein the lancing unit is configured to penetrate a surface of the target that is to be imaged.
10. The device of claim 1 , wherein the marking unit is detachably coupled to the housing.
11. The device of claim 1 , wherein the marking unit is configured to produce the mark within an imaging plane of the imaging unit.
12. The device of claim 1 , wherein the display includes physical reference markers that indicate a location on the target to be marked by the marking unit.
13. The device of claim 7 , wherein the mechanical indentation unit includes a shaft extending from the recessed portion, the shaft having a length less than or equal to a length of the gap.
14. The device of claim 7 , wherein the output display displays a map of the target.
