摘要:
A system for imaging and treating tissue comprises a probe having a deflectable distal tip for carrying an imaging array and a delivery needle for advancement within a field of view of the imaging array. Optionally, the needle will carry a plurality of tines which may be selectively radially deployed from the needle. The imaging array will preferably be provided in a separate, removable component.

[Task] A type of catheters connected to an MDU can be determined without adding any special hardware. [Means for Resolution] There is provided an imaging apparatus for diagnosis which has a motor drive unit (MDU) for being connected to a catheter and for moving and rotating an imaging core accommodated in the catheter along a longitudinal direction of the catheter, and which generates a vascular optical coherence tomographic image and an ultrasound tomographic image of a subject, based on a signal output from the catheter. The apparatus includes a first drive unit that applies an ultrasound drive signal to an ultrasound transceiver accommodated in a distal portion of an imaging core, and that acquires an electric signal indicating a reflected wave, assuming that the catheter is connected to the MDU, a first inspection unit that inspects the presence or absence of the ultrasound transceiver, based on intensity distribution of the electric signal of the reflected wave which is obtained by the first drive unit, a second drive unit that supplies light to an optical transceiver accommodated in the distal portion of the imaging core, and that acquires an electric signal indicating interference light, assuming that the catheter is connected to the MDU, a second inspection unit that generates line image data in a radial direction, regarding a position of the imaging core as an origin, based on the electric signal of the interference light which is obtained by the second drive unit, and that inspects the presence or absence of the optical transceiver, based on pixel data distribution within a predetermined range from a position of the origin, and a determination unit that determines whether the catheter connected to the MDU is any one of the catheter dedicated to diagnosis of the ultrasound tomographic image, the catheter dedicated to diagnosis of the optical coherence tomographic image, and the catheter corresponding to both the ultrasound tomographic image and the optical coherence tomographic image, based on an inspection result of the first inspection unit and an inspection result of the second inspection unit.

There is provided an acoustic wave image generating apparatus and method capable of obtaining an image with good visibility of a needle. In a case where ultrasound waves having an intensity distribution centered on a first direction are transmitted to a subject, ultrasound echoes return from the subject. Ultrasound echo data indicating the ultrasound echoes are phased and added along lines (53) to (55) in virtual reception directions. As the ultrasound transducers transmitting ultrasound waves (51) are updated, a plurality of first ultrasound images (71) to (73) are obtained. Since the ultrasound images (71) to (73) having various angles can be obtained, an image with good visibility of a needle can be obtained in a case where the needle is inserted into the subject.

The invention concerns a detecting apparatus (12) for imaging at least two areas of a brain of a subject (10), the detecting apparatus (12) comprising:—a holder comprising:—a frame (14) devoted to be cemented on the skull of the subject (10), the frame (14) delimitating an inner portion (18) which is transparent to ultrasound waves,—a removable imaging device comprising:—a platform (16) delimitating an inner space (28), the inner space (28) facing the inner portion (18),—a fixing element (30) adapted to temporary fix and lock the platform (16) to the holder,—an ultrasound probe (32), and—a moving stage (34) holding the ultrasound probe (32) and being adapted to move the ultrasound probe (32) within the inner space (28).
摘要:
A method of operating a medical-imaging system is described; the medical-imaging system has an ultrasound-transducer interface configured to operatively interface with an ultrasound transducer including transducer elements; the medical-imaging system also has a spatial sensor configured to provide spatial information indicating spatial movement of the ultrasound transducer; the method includes receiving ultrasound information being associated with a scan-line set having a limited number of selectable scan lines of the ultrasound transducer. Also disclosed is a non-transitory computer-readable medium.
