To provide an ultrasound imaging apparatus capable of displaying an ultrasound stitched image in which an analyte can easily grasp the state of the analyte, an ultrasound imaging apparatus is provided with an ultrasound image generation module which receives ultrasound waves transmitted from a plurality of mutually different positions on the surface of an analyte and reflected in the inside of the analyte and generates ultrasound images corresponding to the respective positions, an image stitcher module which synthesizes the ultrasound images at the respective positions and generates a stitched image of the cross section of the analyte, and a rotation angle adjusting module which adjusts the angle of the stitched image and orients a specific portion included in the stitched image in a predetermined direction.

The purpose is to provide an ultrasound imaging device capable of automatically detecting a boundary of a biological tissue in an ultrasound image. An ultrasound imaging device includes an image generation module which receives ultrasound waves transmitted from a surface of an analyte toward an inside of the analyte and reflected therein to generate an ultrasound image inside the analyte, a reference point setting module which sets a reference point of a tissue of interest of the ultrasound image, a first seed point imparting module which imparts one or more seed points to the ultrasound image with reference point, and a region demarcating module which demarcates a region to which the seed point belongs and divides an image region of the analyte included in the ultrasound image into a plurality of regions according to a type of tissue.

A body tissue to be detected is automatically detected certainly with high precision. An ultrasonic body tissue detecting device may include a transmission/reception unit, a two-dimensional data acquisition unit, a spatial frequency distribution calculation unit and a determination unit. The transmission/reception unit may transmit an ultrasonic signal into a body of a sample and receive an echo signal of the ultrasonic signal. The two-dimensional data acquisition unit may form two-dimensional echo image in a transmitting direction of the ultrasonic signal and in a scanning direction. The spatial frequency distribution calculation unit may perform a spatial frequency conversion of the two-dimensional echo image and calculate a spatial frequency distribution for a determining position. The determination unit may determine whether the determining position is the body tissue to be detected based on a distribution of amplitude in the transmitting direction of the ultrasonic signal and a distribution of amplitude in the scanning direction of the spatial frequency distribution.

Provided is an art in which when an operator grips a probe of an ultrasonic imaging apparatus and moves the probe, it is facilitated to maintain the probe at a suitable angle with respect to an object to be imaged. A probe adapter may include a contact surface having a shape extending along an outer circumference of a cross section of an object to be imaged, and a fixing portion configured to fix a probe having an ultrasonic wave transmitting-receiving surface which transmits and receives an ultrasonic wave at a given angle and expose the ultrasonic wave transmitting-receiving surface to the contact surface side.

An ultrasonic bone evaluation apparatus includes stationary and movable standoffs fitted with respective ultrasonic transducers for transmitting and receiving ultrasound, a moving mechanism for moving the movable standoff, an encoder, a controller, and an inner temperature sensor for determining the temperature of an inner tissue of a body part. The moving mechanism moves the movable standoff toward the stationary standoff to sandwich the body part therebetween. The encoder measures the distance between the two transducers whereas the controller determines the time required for the ultrasound to travel between the transducers when the body part is sandwiched between the standoffs. The controller calculates the speed of sound propagating through the body part from distance and time measurement values, corrects the speed of sound through the body part based on the temperature of the body part measured by the inner temperature sensor, and evaluates the bone of the body part based on the corrected speed of sound.
