The invention is to provide an ultrasonic image with a clear tissue structure while reducing speckle noise of the ultrasonic image. An ultrasonic wave is transmitted from the transducer to the subject, and an echo generated in the subject is received. The first ultrasonic image and the second ultrasonic image are generated using a reception signal. The second ultrasonic image is an image smoother than the first ultrasonic image. The image processing unit calculates filter coefficients using pixel values of corresponding pixels of the first ultrasonic image and the second ultrasonic image, and generates an output image by processing one of the first ultrasonic image and the second ultrasonic image using the filter coefficients.

An apparatus for controlling medical equipment is provided. The apparatus includes patient positioning equipment, and a control system coupled to the patient positioning equipment. The control system is configured to control a function of the medical equipment.

An object information acquisition apparatus, comprises a holding member that holds an object and to be movable relative to the object; a position acquirer that acquires information on a position of the object; a first controller that controls a position of the holding member; a measurement unit that receives acoustic waves from the object; a second controller that controls a position of the measurement unit; an information acquirer that acquires information of the object; and a storage unit that stores history information representing information on a contact state of the holding member with the object, wherein the first controller controls the position of the holding member independently of the control performed by the second controller and adjusts the contact state of the holding member with the object based on the history information.

An examination portion information obtaining apparatus includes an opening to which a portion to be examined of the examinee is inserted, a cup-shaped maintaining member which accommodates at least part of the portion to be examined inserted through the opening, an acoustic wave detector which receives acoustic waves from the portion to be examined, and a movement mechanism which moves the maintaining member relative to the portion to be examined inserted through the opening.

A compression assembly is coupled to the gantry of an ultrasound breast imaging system. The compression assembly includes a pair of compression paddles mounted on a positioning track. Each compression paddle houses a transducer and has a compression material surface for patient contact. A motor moves the compression paddles along the positioning track to immobilize the breast for ultrasound imaging.

Microcalcifications can be detected using quantitative ultrasound tomography. Refraction-corrected reflection images generated from a quantitative ultrasound system can be thresholded, and morphologically analyzed to isolate voxels corresponding to microcalcifications.
