The storage unit stores a time phase at generation of the strain information and the indicator at generation of the strain information in an associated manner. The controller extracts a candidate time phase being a time phase of a candidate based on the indicator associated with each of the time phase.

Abstract: A technique for measuring thoracic vertebral bone density (BMD) and coronary calcium score (CCS). Representatively, BMD was measured and averaged at three consecutive thoracic spines (3T) starting from the left main coronary artery caudally and averaging the results of the measurements at the first, second and third spine regions to obtain a thoracic trabecular bone mineral density measurement. The “reference”, as the 3T BMD value of 30 year old and the piBMD (predicted individual BMD (piBMD) were developed. Based on the “reference”, and piBMD, T and Z score of 3T formula were derived in both genders. The new calibration phantom of TQCT and LQCT was designed. The ratios of CTHU/mg/cc were obtained with varying scanners, which were used to translate the CTHU to density units (mg/cc) in BMD and CCS mass measurement. A processor capable of quantitating both BMD and CCS burden was designed. In image without a calibration phantom, formulas were created to quantitate BMD with a high precision.

Abstract: An apparatus and a method for determining the position of a medical instrument, particularly for the purpose of medical navigation. In order to use a simple system to provide a relatively inexpensive technique for determining positional information, the position and/or orientation of the medical instrument is determined by ascertaining the same on the basis of position finding operations. Electromagnetic fields are first measured and the results of relative field strength measurements are taken as a basis for ascertaining the direction of a line from a transmitter to a receiver. After this direction information is known, it is used to determine the positional information of the medical instrument.
