Head modeling for a therapeutic or diagnostic procedure
First Claim
1. A system for creating a digital three-dimensional reconstruction of a human subject'"'"'s head, the system comprising:
- a treatment coil;
a sensor; and
a processor configured to;
determine a plurality of points associated with the human subject'"'"'s head using the sensor and without requiring the use of magnetic resonance imaging (MRI) image information, x-ray image information, or computer tomography (CT) image information, wherein the plurality of points are devoid of information relating to the human subject'"'"'s hair, and wherein a subset of the plurality of points comprise facial feature information;
generate a fitted head model using a predetermined head model and the plurality of points such that the fitted head model is devoid of information relating to the human subject'"'"'s hair;
determine a location of one or more anatomical landmarks on the fitted head model using the facial feature information, the anatomical landmarks comprising one or more of a nasion, an inion, a lateral canthus, an external auditory meatus, or one or more preauricular points of the human subject;
determine a position of the treatment coil based on the one or more anatomical landmarks and without requiring the use of magnetic resonance imaging (MRI) image information, x-ray image information, or computer tomography (CT) image information; and
perform transcranial magnetic stimulation (TMS) at a treatment location using the treatment coil.

Abstract
A model of a human subject'"'"'s head may be generated to assist in a therapeutic and/or diagnostic procedure. A treatment and/or diagnostic system may generate a fitted head model using a predetermined head model and a plurality of points. The plurality of points may include facial feature information and may be determined using a sensor, for example, an IR or optical sensor. One or more anatomical landmarks may be determined and registered in association with the fitted head model using the facial feature information, for example, without the use of additional image information, such as an MRI image. The fitted head model may include visual aids, for example, anatomical landmarks, reference points, marking of the human subject'"'"'s MT location, and/or marking of the human subject'"'"'s treatment location. The visual aids may assist a technician to perform the therapeutic and/or diagnostic procedure of the human subject.

20. A method for creating a digital three-dimensional reconstruction of a human subject'"'"'s head, the method comprising:
-
determining a plurality of points associated with the human subject'"'"'s head using a sensor by moving a transcranial magnetic stimulation (TMS) coil around the human subject'"'"'s head such that the plurality of points are devoid of information relating to the human subject'"'"'s hair, wherein a subset of the plurality of points comprise facial feature information, and wherein the sensor is configured to determine the location of the TMS coil; generating a fitted head model using a predetermined head model and the plurality of points, such that the fitted head model is devoid of information relating to the human subject'"'"'s hair; determining a location of one or more anatomical landmarks on the fitted head model using the facial feature information, the anatomical landmarks comprising one or more of a nasion, an inion, a lateral canthus, an external auditory meatus, or one or more preauricular points of the human subject; determining a treatment location or a reference point that is used to determine the treatment location on the fitted head model based on the one or more anatomical landmarks and without requiring the use of magnetic resonance imaging (MRI) image information, x-ray image information, or computer tomography (CT) image information; and performing TMS at the treatment location using the fitted head model.
