Abstract
Abstract An apparatus for treating a patient with acoustic waves has a source of acoustic waves and an X-ray locating system, which includes an X-ray radiator and a radiation detector, which are mounted opposite each other on a C-arm. The C-arm is adjustable along its outer circumference around its central axis. The source of acoustic waves is adjustable along the inner circumference of the C-arm such that the acoustic axis of the acoustic wave source constantly intersects the central axis of the C-arm.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
An apparatus for treating a patient with acoustic waves comprising: an X-ray locating system including a C-arm partially surrounding a treatment site and an X-ray source and a radiation detector mounted on said C-arm on opposite sides of said treatment site, and C-arm forming a circular arc and having a central axis; means for holding said C-arm and for rotating said C-arm around said central axis; a source of acoustic waves which propagate towards said treatment site along an acoustic axis; and means for mounting said source of acoustic waves on said C-arm for permitting movement of said source of acoustic waves along said C-arm.
Claim 2
Independent Claim
105 words
An apparatus for treating a patient with acoustic waves comprising: an X-ray locating system including a C-arm partially surrounding a treatment site and an X-ray source and a radiation detector mounted on said C-arm on opposite sides of said treatment site, and C-arm forming a circular arc and having a central axis; means for holding said C-arm and for rotating said C-arm around said central axis; a source of acoustic waves which propagate towards said treatment site along an acoustic axis; and means for mounting said source of acoustic waves on said C-arm for permitting movement of said source of acoustic waves along said C-arm.
Claim 3
Dependent Claim
80 words
An apparatus as claimed in claim 1 wherein said means for holding and rotating said C-arm comprises means for providing said C-arm with a range of rotation through an angle β and wherein said means for mounting said source of acoustic waves on said C-arm comprises means for providing said source of acoustic waves with a range of relative movement through an angle α relative to said C-arm, and wherein the sum of α and β is at least 360°.
Claim 4
Dependent Claim
29 words
An apparatus as claimed in claim 1 further comprising means for rotating said C-arm through at least ±180° around an axis which intersects said central axis of said C-arm.
Claim 5
Independent Claim
127 words
An apparatus for treating a patient with acoustic waves comprising: an X-ray locating system including a C-arm partially surrounding a treatment site and an X-ray source and a radiation detector mounted on said C-arm on opposite sides of said treatment site, said C-arm forming a circular arc and having a central axis; means for holding said C-arm for rotating said C-arm around said central axis; a source of acoustic waves which propagate towards said treatment site along an acoustic axis; and means for mounting said source of acoustic waves on said C-arm for permitting circumferental movement of said source of acoustic waves along said C-arm and for maintaining said acoustic axis of said source of acoustic waves in constant intersection with said central axis of said C-arm.
Claim 6
Independent Claim
127 words
An apparatus for treating a patient with acoustic waves comprising: an X-ray locating system including a C-arm partially surrounding a treatment site and an X-ray source and a radiation detector mounted on said C-arm on opposite sides of said treatment site, said C-arm forming a circular arc and having a central axis; means for holding said C-arm for rotating said C-arm around said central axis; a source of acoustic waves which propagate towards said treatment site along an acoustic axis; and means for mounting said source of acoustic waves on said C-arm for permitting circumferental movement of said source of acoustic waves along said C-arm and for maintaining said acoustic axis of said source of acoustic waves in constant intersection with said central axis of said C-arm.
Claim 7
Dependent Claim
80 words
An apparatus as claimed in claim 4 wherein said means for holding and rotating said C-arm comprises means for providing said C-arm with a range of rotation through an angle β and wherein said means for mounting said source of acoustic waves on said C-arm comprises means for providing said source of acoustic waves with a range of relative movement through an angle α relative to said C-arm, and wherein the sum of α and β is at least 360°.
Claim 8
Dependent Claim
63 words
An apparatus as claimed in claim 4 wherein said source of acoustic waves is a source of focused acoustic waves which converge in a focus zone lying on said acoustic axis, and wherein said means for maintaining said constant intersection is a means for maintaining said focused zone, at least during treatment with said acoustic waves, on said central axis of said C-arm.
Claim 9
Dependent Claim
29 words
An apparatus as claimed in claim 4 further comprising means for rotating said C-arm through at least ±180° around an axis which intersects said central axis of said C-arm.
