Abstract

Abstract An ultrasound therapy apparatus having an applicator. The applicator comprises at least one ultrasonic beam emitter, at least two ultrasonic transducers, and a support member. The beam emitter emits an ultrasonic beam onto an object within a patient, for the purpose of treating the object. The transducers apply ultrasonic beams to the patient and detect ultrasonic echoes coming from the patient, thereby to form two tomograms, each of a selected plane of the patient, one plane intersecting with the other on a line passing through a region in which the beam emitted by the beam emitter is focused. The support member supports the beam emitter and the transducers in a specific positional relationship. Receivers receive echo signals corresponding to the ultrasonic echoes. Two displays display tomograms formed from these echo signals. They also display a first marker, which indicates a region in which the ultrasonic beam emitted from the beam emitter is focused, and also a second marker, which represents an intersection line of the two planes. By referring to these markers, an operator can set the applicator in a position whereby the beam emitted from the beam emitter is focused onto the object.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 240 words
An ultrasound therapy apparatus for a treating of an object within a patient, said apparatus comprising: at least one ultrasonic beam emitter means for emitting an ultrasonic beam onto the object; at least two ultrasonic transducer means for applying ultrasonic beams to the patient, and detecting ultrasonic echoes coming from the patient; support means supporting said ultrasonic beam emitter and said ultrasonic transducers in a specific positional relationship; means for mechanically driving said support means such that the beam emitted from said ultrasonic beam emitter means is focused at a given position within the patient; means for supplying drive signals to said ultrasonic beam emitter means; signal-receiving means for receiving echo signals corresponding to the ultrasonic echoes detected by said ultrasonic transducer means; means for forming first and second tomograms in accordance with the echo signals supplied from said signal-receiving means, each tomogram being of a selected plane of the patient, one plane intersecting with the other on a line which passes through a region in which the beam emitted by said ultrasonic beam emitter means is focused; and display means for displaying the first and second tomograms, for displaying first markers indicating a region in which the ultrasonic beam emitted by said ultrasonic beam emitter means is focused and being superposed on the first and second tomograms, and for displaying second markers representing the intersecting line of the two planes and being superposed on the first and second tomograms.
Claim 2
Dependent Claim 240 words
An ultrasound therapy apparatus for a treating of an object within a patient, said apparatus comprising: at least one ultrasonic beam emitter means for emitting an ultrasonic beam onto the object; at least two ultrasonic transducer means for applying ultrasonic beams to the patient, and detecting ultrasonic echoes coming from the patient; support means supporting said ultrasonic beam emitter and said ultrasonic transducers in a specific positional relationship; means for mechanically driving said support means such that the beam emitted from said ultrasonic beam emitter means is focused at a given position within the patient; means for supplying drive signals to said ultrasonic beam emitter means; signal-receiving means for receiving echo signals corresponding to the ultrasonic echoes detected by said ultrasonic transducer means; means for forming first and second tomograms in accordance with the echo signals supplied from said signal-receiving means, each tomogram being of a selected plane of the patient, one plane intersecting with the other on a line which passes through a region in which the beam emitted by said ultrasonic beam emitter means is focused; and display means for displaying the first and second tomograms, for displaying first markers indicating a region in which the ultrasonic beam emitted by said ultrasonic beam emitter means is focused and being superposed on the first and second tomograms, and for displaying second markers representing the intersecting line of the two planes and being superposed on the first and second tomograms.
Claim 3
Dependent Claim 28 words
An ultrasound therapy apparatus according to claim 1, further comprising a bathtub in which the patient sits in order to receive treatment, and which contains said support means.
Claim 4
Dependent Claim 57 words
An ultrasound therapy apparatus according to claim 1, further comprising: a bed on which the patient lies to receive treatment and which contains said support means; a tank located below said bed and having an open top; and a membrane covering said open top and made of a material able to pass ultrasonic waves but not water.
Claim 5
Dependent Claim 34 words
An ultrasound therapy apparatus according to claim 1, wherein said ultrasonic beam emitter means is provided in a predetermined region of said support means, and said ultrasonic transducer means are provided outside this region.
Claim 6
Dependent Claim 39 words
An ultrasound therapy apparatus according to claim 1, wherein each of said ultrasonic transducer means comprises an array of piezoelectric elements, whereby the ultrasonic beam emitted from the ultrasonic transducer means scans a region of interest within the patient.
Claim 7
Dependent Claim 56 words
An ultrasound therapy apparatus according to claim 1, further comprising means for detecting the position of the object on the basis of said echo signals, and means for controlling said means for mechanically driving the support means in such a manner that said region, in which the ultrasonic beam is focused, is positioned at the object.
