A method for precisely identifying a fixed point of reference on a human jaw including providing a mandibular c-clamp, which has a shaft, an upper prong fixedly connected to the shaft, a lower prong movable along the shaft, and a wedge configured to selectively secure the lower prong to the shaft. The upper prong of the mandibular c-clamp is inserted into a patient's mouth. The lower prong of the mandibular c-clamp is then moved along the shaft to close on a patient's chin compressing patient's soft tissue, and a position of the lower prong is secured on the shaft using the wedge so that the lower prong is no longer movable along the shaft. A sensor is then secured to a designated area of the mandibular c-clamp so as to provide a reference point.

Mandibular c-clamp

A method for continuously evaluating an X-ray unit. The method includes placing an X-ray sensor converter having a photo diode and a scintillation crystal in a path of an X-ray beam emitted by the X-ray unit, using the X-ray sensor converter to convert an X-ray beam energy into an electric signal, providing an amplifier connected to the X-ray sensor converter, conveying the electric signal from the X-ray sensor converter to the amplifier, amplifying the electric signal with the amplifier, and measuring a spectrum of the X-ray tube energy by continuously sampling and quantifying the amplified electric signal.

A method for performing a stereotactic brain surgery. The method includes first interposing a left and a right anthropological baselines on a patient's face, each trago-orbital anthropological baseline connecting an orbitale point and an auricular point on a corresponding side of the patient's face. A headgear unit having a pair of temple elements and a front housing, where the front housing includes at least two cameras and a 3D compass, is then positioned on a patient's head. Each of the two cameras is adjusted such that its view field picks up one of the two trago-orbital anthropological baselines on the patient's face. These view fields of the two cameras are then used to construct a Human Skull Base Plane as a plane formed by the left and right anthropological baselines when these anthropological baselines are parallel and aligned. The same view fields of the two cameras are also used to identify a precise center of the patient's face, and a center of the front housing is then positioned in alignment with the center of the patient's face. The 3D compass is then positioned into a measuring plane coinciding with the Human Skull Base Plane, and is used to quantitatively measure a three-dimensional orientation of the patient's head at the time when the 3D compass is positioned within the measuring plane coinciding with the constructed Human Skull Base Plane. An image of a patient's brain is then obtained and stored in correlation with the measured three-dimensional orientation of the patient's head. Prior to the surgery, the patient's head is positioned into the same position in which the image was taken. A stereotactic brain surgery is then performed using the stored image.

A method and apparatus for determining a three-dimensional orientation of a human head. The method includes first interposing a left and a right anthropological baselines on a patient's face, each anthropological baseline connecting an orbitale point and an auricular point on a corresponding side of the patient's face. A headgear unit having a pair of temple elements and a from housing rotatably attached to the temple elements, where the front housing includes at least two cameras and a 3D compass all movable within the front housing, is then positioned on a patient's head. Each of the two cameras is adjusted such that its view field picks up one of the two anthropological baselines on the patient's face. These view fields of the two cameras are then used to construct a Human Skull Base Plane as a plane formed by the left and right anthropological baselines when these anthropological baselines are parallel and aligned. The 3D compass is then positioned into a measuring plane coinciding with the Human Skull Base Plane, and is used to quantitatively measure a three-dimensional orientation of the patient's head at the time when the 3D compass is positioned within the measuring plane coinciding with the constructed Human Skull Base Plane.

An X-ray system including an X-ray source generating X-rays, an X-ray receptor receiving the X-rays and generating X-ray images, a patient satellite and a server connected to the X-ray source, the X-ray receptor and the patient satellite. The patient satellite is secured to a patient positioned between the X-ray source and the X-ray receptor and includes an angular orientation sensor and a distance sensor. The angular orientation sensor detects an angular orientation of the patient and outputs a signal to an operator allowing the operator to position the patient with respect to the X-ray source and the X-ray receptor so as to eliminate an angular distortion in the X-ray images. The distance sensor measures a distance between the patient and the X-ray receptor.
