Head modeling for a therapeutic or diagnostic procedure

A system for creating a digital three-dimensional reconstruction of a human subject's head, the system comprising:

• an infrared sensor;
• and
• a processor configured to:
• determine a plurality of points associated with the human subject's head using the infrared sensor and without the use of additional 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;
• determine 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 the use of additional image information, wherein the treatment location corresponds to an anatomical region within a human brain and is associated with a neuropsychiatric disorder;
• and
• perform transcranial magnetic stimulation (TMS) using the fitted head model and the treatment location or the reference point that is used to determine the treatment location.

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 an infrared sensor and without the use of additional image information 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 infrared 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;
• 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 the use of additional image information, wherein the treatment location corresponds to an anatomical region within a human brain and is associated with a neuropsychiatric disorder;
• and performing TMS using the fitted head model and the treatment location or the reference point that is used to determine the treatment location.
