  • Patent number: 11850099
    Abstract: According to one embodiment, an ultrasonic diagnostic apparatus includes an ultrasonic probe and processing circuitry. The processing circuitry causes the ultrasonic probe to perform a first scan and second scan in a same scan sequence, wherein the first scan is for calculating a first index value based on a displacement of tissue by a shear wave that propagates through a living body, the second scan for calculating a second index value indicating an attenuation of a reflected wave signal of an ultrasonic wave applied into the living body. The processing circuitry generates a first image based on the first index value, and generates a second image based on the second index value. The processing circuitry causes a display to simultaneously display the first image and the second image.

  • Patent number: 11835669
    Abstract: A method of normalizing detector elements in an imaging system is described herein. The method includes a line source that is easier to handle for a user, and decouples the normalization of the detector elements into a transaxial domain and an axial domain in order to isolate errors due to positioning of the line source. Additional simulations are performed to augment the real scanner normalization. A simulation of a simulated line source closely matching the real line source can be performed to isolate errors due to physical properties of the crystals and position of the crystals in the system, wherein the simulated detector crystals are otherwise modeled uniformly. A simulation of a simulated cylinder source can be performed to determine errors due to other effects stemming from gaps between the detector crystals.
