Devices and methods for fetal imaging are described. In some embodiments, a fetal imaging device includes, but is not limited to, a garment wearable over a portion of a body bearing a fetus; one or more ultrasound sources coupled to the garment and configured to apply one or more ultrasonic signals to the body; a first array of ultrasound receivers coupled to the garment and configured to receive one or more ultrasonic signals from the body; and a second array of ultrasound receivers coupled to the garment and configured to receive one or more ultrasonic signals from the body, the second array of ultrasound receivers being independently addressable and spatially separated from the first array of ultrasound receivers.

This photoacoustic imaging device (100) comprises: a display unit (40) that rewrites a screen (40a) at a predetermined refresh rate (RC) and that displays an image on the screen; and a control unit (30) that performs the acquisition of a detection signal and irradiation with light by a semiconductor light-emitting-element light-source unit at a sampling cycle (SC) shorter than the cycle of the predetermined refresh rate, and that creates an image to be displayed on the display unit from the detection signal detected according to the sampling cycle.

An assistance apparatus for assisting creation of an interpretation report obtains a set of regions of interest, which are determined as regions that were observed, of medical image data of a subject that is displayed as an interpretation target, and a set of described regions, which are regions that correspond to description of an interpretation report about the medical image data of a subject. The assistance apparatus determines consistency between the set of regions of interest and the set of described regions, and lets a display unit display a result of the determination.

A subject information acquiring device has: an acoustic detector which receives an acoustic wave propagated in a subject and converts into an electrical signal; and a data processing device which generates a subject information distribution using the electrical signal, and the data processing device has a matching processing unit which acquires a similarity distribution by calculating a similarity between: template data indicating a relationship between a real image; and an artifact and the subject information distribution used as a matching information distribution, so that it is possible to provide a photoacoustic image forming diagnosing device which can distinguish between an image and a background even when the contrast is poor.

This photo-acoustic imaging device (100) is provided with: light emitting diodes (16); an acoustic wave detecting unit (14); a device main body (2) in which a light source driving unit (22) including a power supply unit (22a) and a signal generating unit (22b) is provided; and a coaxial cable (3). For the coaxial cable (3), an external conductor (3c) of the coaxial cable (3) is connected to the power supply unit (22a) and an internal conductor (3a) of the coaxial cable (3) is connected to the signal generating unit (22b).

A method of displaying electrophysiology information includes obtaining a three-dimensional medical image of an anatomical region, registering a localization system to the model; localizing an electrophysiology catheter within the anatomical region; displaying a representation of the localization of the electrophysiology catheter on the model; and displaying image slices of the model. The image slices are selected based upon the localization of the electrophysiology catheter. For example, the image slices can pass through a user-selected localization element carried by the electrophysiology catheter. Rigid and/or non-rigid transforms can be used to register the localization system to the model. Electrophysiology data collected by the catheter can be displayed on the model and/or the image slices thereof. The three-dimensional medical image and/or the electrophysiology data can also be time-varying. In embodiments, scalar maps can also be displayed on the model.

One or more techniques and/or systems described herein provide for generating a radiographic image and ultrasound image depicting parallel planes of an object under examination and may be used in conjunction with radiographic or ultrasound techniques known to those in the field (e.g., x-ray tomosynthesis, computed tomography ultrasound imaging, etc.). An ultrasound frontend component is configured to transmit ultrasound waves in a direction substantially parallel to a trajectory of radiation. In one example, one or more radiographic images of an object are spatially coincident to one or more ultrasound images of the object in the same position and/or geometric shape/volume, and the images may be combined to generate a combined image depicting features of the ultrasound image (e.g., the sensitivity of the ultrasound image) and features of the radiographic image (e.g., the morphological details of the radiographic image).

A measurement unit is attached to a measurement subject and measures acceleration in time series. A body movement calculation unit obtains the magnitude of body movement indicating the magnitude of a motion of the measurement subject based on acceleration measured by the measurement unit. A singular point extraction unit extracts, as a singular point, a time point at which the magnitude of body movement obtained by the body movement calculation unit exceeds a threshold value. A matching unit rectifies a change in a photoacoustic signal between before and after the singular point extracted by the singular point extraction unit.
