Abstract:
An adjustment apparatus is used for ultrasound examination of a subject by transmitting ultrasound to the subject and receiving the ultrasound reflected from the subject. The apparatus includes: a change unit configured such that one end is connected to a suction pump and the other end is provided at a portion of a channel leading to a contact portion with the subject, to change suction force of the suction pump on the other end; and a damper for suppressing change in the suction force. The change unit includes: a cylinder having first and second portions for communicating with one end side and the other end side of the channel, respectively; a piston slidable in the cylinder to change a communication state between the first and second portions; and a spring for biasing the piston toward a direction of causing the first and second portions not to communicate with each other.
Abstract:
An energy radiation treatment method comprises: administering a medicinal agent to an affected part; performing energy radiation with a predetermined energy on the affected part; and confirming therapeutic effects by the energy radiation on the affected part, wherein in the administering, a determination based on at least one ultrasound image based on ultrasound waves reflected from the affected part is performed.
Abstract:
For providing an, ultrasound endoscope capable of obtaining a favorable elastography image by a simple configuration without upsizing a distal end portion, an ultrasound endoscope is configured having an ultrasound probe arranged at a distal end rigid portion, an auxiliary water feeding channel opening through which fluid is ejected from a vicinity of the ultrasound probe in a projecting direction of the ultrasound probe, an auxiliary water feeding channel communicating with the auxiliary water feeding channel opening, and an adjustment valve for variably adjusting a flow rate of the fluid flowing through the auxiliary water feeding channel among two or more states.
Abstract:
An ultrasound imaging system includes an ultrasound imaging device configured to transmit and receive a signal based on transmission and reception of an ultrasound wave. The ultrasound imaging device includes a processor including hardware. The processor is configured to: generate a plurality of pieces of data of ultrasound images of an inside of a subject based on the signal, the ultrasound images being spatially separated from one another; invert a magnitude relationship of a luminance value of each of pixels in each of the ultrasound images; automatically set a first boundary across which the luminance value changes by a predetermined amount based on data of one of the ultrasound images; and automatically detect a second boundary in each of the ultrasound images based on the set first boundary.
