An ultrasound elasticity imaging apparatus includes an elastic data processing section which processes a received signal detected by an ultrasound probe and generates elastic frame data, a display evaluation section which evaluates a display value of the elastic frame data based on various data in the generation of the elastic frame data, a display processing section which performs image processing of the elastic frame data according to the evaluation result by the display evaluation section, and a display section which displays an elastic image based on the elastic frame data processed by the image processing section.

Ultrasound probe and ultrasound elasticity imaging apparatus

Ultrasound diagnostic apparatus includes an unitfor forming time series tomographic images on the basis of a reflection echo signals received by ultrasound probe, an unitfor obtaining the elasticities of body tissue on the basis of the reflection echo signals and forming elasticity images on times series, an unitfor forming a superimposition image on time series by superposing the tomographic image on the elasticity image, an unitfor inputting an instruction for controlling superimposition image formation, and an unitfor displaying the superimposition image. The ultrasound diagnostic apparatus further includes a freezing control portion () for outputting an image, as a frozen image, selected in response to a freezing instruction for freezing the display operation on time series of any of the tomographic image or the elasticity image input into the input unit to the superimposition image forming unit.

Ultrasound diagnostic apparatus and method of displaying ultrasound image

An ultrasonic imaging apparatus according to the present invention includes an ultrasonic probe () for receiving and transmitting ultrasonic waves from/to an object (), ultrasound image structuring means () for generating an ultrasound image from a reflected echo signal received by the ultrasonic probe, elastic image structuring means () for obtaining a physical quantity of the elasticity of a region of the object corresponding to the ultrasound image from the reflected echo signal and generating a color elastic image, display means () for overlaying the ultrasound image to the color elastic image, or arranging the ultrasound image and the color elastic input means () for variably setting a corresponding relationship between a hue of the color elastic image and the level of the physical quantity displayed on the screen. The level of the elasticity, such as the strain of each region in the tissue or an elastic modulus, is displayed with colors in accordance with the interest of the examiner, thus improving the convenience of use.

Ultrasonic imaging apparatus

An ultrasound diagnostic apparatus includes an ultrasound probe which transmits/receives an ultrasound wave with respect to a subject to be diagnosed, an ultrasound wave transmit section which transmits an ultrasound wave for driving the ultrasound probe, a pressing section which applies an external pressure to the subject, a displacement measuring section which obtains two tomographic image data different in time series from a reflected echo signal received from the ultrasound probe and measures a displacement of each part in the subject based on the two tomographic image data, an image generating section which generates an elastic image from elasticity information based on the displacement of each part measured by the displacement measuring section, and a display section which displays the generated elastic image. Further, a pressing decision section decides whether or not the pressing operation by the pressing section is proper.

An ultrasound probe includes an ultrasound wave transmit/receive surface coming into contact with a contact surface of a subject, an ultrasound wave transmit/receive section which transmits an ultrasound wave to the subject via the ultrasound wave transmit/receive surface and the contact surface and receives an ultrasound wave reflected in the subject, and a pressing mechanism for performing a pressing operation for applying a pressure to the contact surface perpendicularly to the ultrasound wave transmit/receive surface via the ultrasound wave transmit/receive surface.

Ultrasonic probe and ultrasonic elasticity imaging device

An ultrasonographic apparatus includes: an ultrasonic probefor transmitting/receiving an ultrasonic wave to/from a patient, meansfor generating an ultrasonic transmission signal and transmitting it to the ultrasonic probe, meansfor receiving a reflection echo signal received by the ultrasonic probe; meansfor re-constructing a form image according to the reception signal processed by the reception processing means; meansfor re-constructing an elasticity image according to the reception signal processed by the reception processing means; meansfor displaying the form image and the elasticity image; meansfor switching between the form image mode and elasticity image mode; and meansfor performing control so as to selectively acquire the form image and the elasticity image in the measurement period of the elasticity image mode switched by the mode switching means. Thus, it is possible to perform measurement associated with acquisition of both the form image and the elasticity image of the biological tissue and improve the image quality of the form image such as a B mode image and the image quality of the elasticity image such as elasticity ratio and elasticity distortion.
