Title: Device and method to correct spherical aberration

IPC: G11B7/1369
Filed: 2002-07-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a spherical aberration correcting device which effectively correct spherical aberration.  <P>SOLUTION: In the device, test recording is conducted for an optical disk and characteristics related to the parameters having correlation with spherical aberration are obtained by the test recording. When jitter, βvalue, modulation degree and asymmetry or the like are used as the parameters, the characteristics are obtained by reproducing recorded data after the test recording. In the mean time, when pit level, pit ratio or the like are used as the parameters, characteristics during the test recording are obtained. Based on the obtained characteristics, an optimum spherical aberration correction amount that minimizes the amount of spherical aberration is determined to correct the spherical aberration. By conducting test recording immediately prior to an actual information recording, spherical aberration is optimally corrected under the environment in which the actual information recording is conducted and good recording is performed.  <P>COPYRIGHT: (C)2004,JPO

Title: Ultrasonographic system, distortion distribution display method, and elastic modulus distribution display method
Inventor: SHIINA TAKESHI
IPC: A61B8/00
Filed: 2002-07-31
Abstract: <P>PROBLEM TO BE SOLVED: To estimate displacement distribution corresponding to lateral displacement and to reconfigure elastic modulus distribution only from distortion distribution in the direction of ultrasonic beam (axial direction).  <P>SOLUTION: A correlation computing means calculates the corelation between signals before and after compression of a subject tissue using an envelope signal outputted from an orthogonal detecting means. At this time, since calculation of correlation at intervals of samples becomes an enormous amount of calculation, the correlation computing means calculates a correlation coefficient at every scan line discretized by each designated value in the axial direction in a two-dimensional correlation window and in the lateral direction intersecting perpendicularly to the axial direction. Thus, the calculation amount can be decreased remarkably to enable real-time display. An elastic modulus estimating means divides the subject tissue into a finite number of rectangular parallelepiped elements for three-dimensional finite element modeling, supposing that the subject tissue is isotropic elastic body and near non-compressive, and estimates elastic modulus distribution information using distortion distribution information in an elasticity equation, supposing that elastic modulus, stress and distortion are uniform in each element.  <P>COPYRIGHT: (C)2004,JPO
