A method for display processing of 3D image data includes obtaining 3D volume data of the head of a target body; detecting a transverse section at an anatomical position from the 3D volume data according to image characteristic of the head of the target body in a transverse section related to the anatomical position; and displaying the transverse section.

A subject is avascularized while changing the avascularization pressure between the avascularized condition and the non-avascularized condition. A receiving circuit receives a detection signal obtained by detecting a photoacoustic wave generated in the subject by emission of measurement light to the subject. Photoacoustic image generation means generates a photoacoustic image based on the detection signal of the photoacoustic wave. Motion detection means detects the motion of each of a plurality of control points set in each photoacoustic image based on photoacoustic images at a plurality of times. Region of interest setting means sets a region of interest based on the motion detected at each control point. Blood flow information generation means generates blood flow information based on the signal strength of the photoacoustic image in the region of interest.

Apparatus and methods are described including an endoluminal device configured to move along a portion of a lumen of a subject's body, an extraluminal imaging device, and at least one computer processor. While the endoluminal device moves along the portion of the lumen, a display displays an extraluminal image of the lumen in which a first indication of a location of the lumen is shown. The extraluminal imaging device acquires a sequence of extraluminal images of the endoluminal device moving along the portion of the lumen. The indication of the location of the lumen that is displayed is updated based upon the acquired sequence of extraluminal images, and the acquired sequence of images is displayed with the updated indication of the location of the lumen overlaid upon the images. Other applications are also described.

Provided is an ultrasound automated method for measuring the thickness of the walls of arteries. The method includes utilizing an apparatus that includes an ultrasonic device, a tracking system, a QI system, a 3D generator, a cross-section generator, a display driver, and a display. The ultrasound automated method includes, e.g.,: defining a fixed frame of reference, detecting the position of the ultrasonic device in respect to the fixed frame of reference, recording a set of 2D images, to be transmitted by the ultrasonic device to the database of the QI system structure, placing the reference sensor over the arterial walls, selecting the proximal and distal walls of the arteries, selecting the length of the walls to be measured in order to proceed to thickness determination, investigating over the length of the selected coronary segment, the mean arterial thickness (AT) and lumen area (LA).

In an ultrasound system and a control method of the ultrasound system, a first position of an ultrasound probe on a nipple of a subject and a second position of the ultrasound probe on epidermis above a region of interest in a three-dimensional space are acquired, and the region of interest and the epidermis in an ultrasound image are specified. A first linear distance L1 from the first position to the second position in the three-dimensional space and a second linear distance L2 from the region of interest to the epidermis above the region of interest in the ultrasound image are calculated. Then, a third linear distance L3 from the nipple to the region of interest in the ultrasound image is calculated on the basis of the first linear distance L1 and the second linear distance L2.

A method executed at least in part by a computer and comprising responding to an instruction requesting an ultrasound exam by wirelessly communicating with an ultrasound system by transmitting a query signal and receiving a response signal from the ultrasound system. Response can determine whether or not the ultrasound system is configured with at least a suitable transducer for the requested ultrasound exam. The method determines whether or not an operator identified in the response signal is trained to administer the requested ultrasound exam. A schedule signal for the requested ultrasound exam is transmitted. A displayed message indicates progress of the requested ultrasound exam.

An ultrasound imaging system and method employs hardware and/or software to monitor values indicative of analog-to-digital converter (ADC) saturation for each channel as a function of depth. Any of a number of actions may be performed based on the monitored values. For example, analog amplification or TGC may be adjusted to enhance the use of a dynamic range of ADCs while reducing or eliminating ADC saturation. A TGC profile may be adjusted. An alert may be provided. A power consumption may be adjusted.

A guidance apparatus is provided for use with a portable imaging apparatus and an image display. The guidance apparatus comprises a coupling mechanism which may include a slip ring portion structured for receiving the imaging apparatus therein. The coupling mechanism can be structured for: facilitating orienting the image display device to provide a direct line of sight of an area imaged by the imaging apparatus; adjusting to facilitate rotation of the image display device in at least one 360-degree plane of rotation about a longitudinal axis extending through the imaging apparatus; allowing selection of an image display device position associated with a viewing angle of the image display device; and allowing the coupling mechanism, the image display device, and the imaging apparatus, in combination, to be held in a single hand of a user during performance of an imaging procedure.
