The length of an optical fiber from a portion aligned with the rear end of an insertion needle to a fixing portion is a length obtained by adding a predetermined extra length to a linear distance between the rear end of the insertion needle in a case where the insertion needle is located at a protruding position (insertion position) and an optical fiber fixing position of a grip portion. There is provided a fiber feeding adjustment mechanism that suspends the optical fiber with a first suspension portion and a second suspension portion so as to make a detour in a state in which there is no slack, and changes the detour length continuously according to the movement of the insertion needle in a case where the insertion needle moves between the retracted position and the protruding position, thereby maintaining a state in which the optical fiber is suspended without slack.

Systems and methods for network-based ultrasound imaging are provided, which can include a number of features. In some embodiments, an ultrasound imaging system images an object with three-dimensional unfocused pings and obtains digital sample sets from a plurality of receiver elements. A sub-set of the digital sample sets can be electronically transferred to a remote server, where the sub-set can be beamformed to produce a series of two-dimensional image frames. A video stream made up of the series of two-dimensional images frames can then be transferred from the remote server to a display device.

Ultrasound signal processing device including: transmitter performing transmission events while varying a focal point; receiver generating, for each transmission event, receive signal sequences for transducer elements; delay-and-sum calculator generating, for each transmission event, a sub-frame acoustic line signal including an acoustic line signal for each measurement point located on target lines passing through the focal point and composing a target line group; and synthesizer combining sub-frame acoustic line signals to generate a frame acoustic line signal. The target lines are straight lines, and any measurement point, on any target line, that is spaced away from the focal point by a predetermined distance or more satisfies a condition that distance between the measurement point and a most nearby measurement point on the same target line is smaller than distance between the measurement point and a most nearby one among measurement points on an adjacent target line.

An ultrasonic diagnosis apparatus includes a position detector, and control circuitry. The position detector detects a position in a three-dimensional space of one of an ultrasonic image and an ultrasonic probe. The control circuitry uses a vivisection view defined in a three-dimensional space. The control circuitry associates a structure related to a subject included in the ultrasonic image with a structure included in the vivisection view using a position and orientation in a first three-dimensional coordinate system of the structure related to the subject included in the ultrasonic image and a position and orientation in a second three-dimensional coordinate system of the structure included in the vivisection view.
