Method of automatically determining imaged body posture in medical image display

A method of determining the imaged posture of a medical image, comprising the steps of:

• (i) generating a histogram of an image signal bearing a transmitted image of a human body;
• (ii) determining the separation of said histogram;
• and
• (iii) determining the imaged posture of said image based on said separation.

A method of determining the imaged posture of a medical image, comprising the steps of:

• (i) generating a histogram of an image signal bearing a transmitted image of a human body;
• (ii) determining the degree of matching between a pattern of said histogram and a plurality of reference image signal histogram patterns predefined of imaged postures of the image;
• and
• (iii) determining the imaged posture of said image based on said degree of matching.

A method of determining the imaged posture of a medical image, comprising the steps of:

• (i) generating a histogram of an image signal bearing a transmitted image of a human body;
• (ii) determining a function approximating a pattern of said histogram;
• (iii) thereafter, determining a derivative of second order of said function;
• (iv) checking whether said derivative of second order is of a positive or negative value in a predetermined section of the histogram, the section corresponding to a region in the image;
• and
• (v) determining the imaged posture of said image based on whether said derivative of second order is of a positive or negative value.

A method of determining the imaged posture of a medical image, comprising the steps of:

• (i) generating a histogram of an image signal bearing a transmitted image of a human body;
• (ii) detecting whether said histogram is basically of a single-peak form or a double-hump form;
• and
• (iii) determining the imaged posture of said image based on whether said histogram is basically of a single-peak form of a double-hump form.

A method of determining the imaged posture of a medical image, comprising the steps of:

• (i) generating a histogram of an image signal bearing a transmitted image of a human body;
• (ii) determining the dispersion of said histogram;
• and
• (iii) determining the imaged posture of said image based on said dispersion.
