A needle guide device comprising:
- a needle;
- a controller;
- and
- a display driven by the controller and configured to indicate a difference between an ideal angle and a current angle of the needle.
A method of guiding a needle comprising:
- determining an ideal angle from an entry point of a needle of needle guide in a patient to a target position of the needle for treatment of the patient;
- and
- displaying an icon on the needle guide that indicates a difference between a current angle of the needle guide and the ideal angle.
A non-transitory computer-readable medium including executable instructions that when executed by a processor cause the processor to perform the steps of:
- determining a difference between an ideal angle that is an angle from an entry point of a needle of a needle guide in a patient to a target position of the needle for treatment of the patient;
- and driving a display to display an icon on the needle guide that indicates a difference between a current angle of the needle guide and the ideal angle.
The non-transitory computer-readable medium further causing the processor to drive the display to display the icon to indicate a difference between a current depth of the needle in the patient and an ideal depth of the needle to the target position.
