A method and system for non-invasive hemodynamic assessment of coronary artery stenosis based on medical image data is disclosed. Patient-specific anatomical measurements of the coronary arteries are extracted from medical image data of a patient. Patient-specific boundary conditions of a computational model of coronary circulation representing the coronary arteries are calculated based on the patient-specific anatomical measurements of the coronary arteries. Blood flow and pressure in the coronary arteries are simulated using the computational model of coronary circulation and the patient-specific boundary conditions and coronary autoregulation is modeled during the simulation of blood flow and pressure in the coronary arteries. A wave-free period is identified in a simulated cardiac cycle, and an instantaneous wave-Free Ratio (iFR) value is calculated for a stenosis region based on simulated pressure values in the wave-free period.

System and processes for optimal selection of teeth for dentures based on the anatomical measurements and bite impressions of the patient. This information is applied in an iterative manner to rules that balance the anatomical and aesthetic considerations to select the best teeth for a patient. The system may also use this information in an iterative manner to rules that balance the anatomical and aesthetic considerations to design the optimal denture base for the patient as well.

A mobile, hand-held communication device with a digital display, and a 3D camera for acquiring a three-dimensional image of the human body is programmed to function as a digital anthropometer. The user digitizes anatomical landmarks on the displayed image to quickly obtain anatomical measurements which are used with a known morphological relationship to make an anatomical prediction for clothing measurement, body composition, orthotic and insert manufacturing, and postural displacement with accuracy and without external equipment.

To obtain more accurate image recognition results while alleviating the burden on the user to check the image recognition results. An image recognition unit recognizes a predetermined structure in an image representing a subject, then a recognition result judging unit measures the predetermined structure on the image recognized by the image recognition unit to obtain a predetermined anatomical measurement value of the predetermined structure, automatically judges whether or not the anatomical measurement value falls within a predetermined standard range, and, if it is outside of the range, judges the image recognition result to be incorrect.

The invention provides a method used for measuring the positron emission measurement information of a body area which is corresponding to at least a periodic motion process in a positron emission fault angiography category. The invention comprises the steps in which the positron emission measurement in the area to be checked is carried out so as to measure the functional positron emission measurement information; meanwhile, an anatomical imaging method with high time resolution, more particularly the computer fault angiography category method is adopted to collect and restrict the anatomical measurement information of the body area to be checked on a photographing plane at least in a measurement time section, the anatomical imaging method with high time resolution is then adopted to collect and dissect the total four-dimensional data array of the anatomical reference measurement information in at least a motion process period, and the positron emission measurement information in the measurement time section led to be corresponding to the anatomical reference information by the comparison between the anatomical measurement information which is restricted on the photographing plane and belongs to the measurement time section of the positron emission measurement and the four-dimensional anatomical reference measurement information according to the anatomical imaging method.
