An ergonomic housing for electroacoustic transducers, particularly for ultrasound imaging, includes at least an inner space (4) housing, one or more electroacoustic transducers (5) and possible further electric and/or electronic components (6/7). The housing (1) has at least an acoustic window (2) at which the one or more electroacoustic transducers (5) are placed. Further included is a handle part (101) composed of an opposing gripping surface having a shape that is ergonomically fitted for being gripped by a hand or a portion thereof. The gripping surface has such a shape or profile (301) to be ergonomically fitted for being gripped by inserting it in the hollow between two adjacent fingers of the hand.
摘要:
A nuclear magnetic resonance imaging device has a magnetic structure which defines a cavity for housing at least part of the body of a patient with a magnetic field which permeates at least part of the cavity, an opening provides access to the imaging cavity from outside of the magnetic structure and electrically conductive and electrically grounded shielding provided at the opening is movable between a first inactive configuration wherein the opening is substantially open and an active configuration in which the opening is at least partially closed by the shielding

A patient table is used in combination with a biomedical apparatus such as a magnetic resonance imaging machine. The table includes a supporting surface sized to accommodate at least a part of the patient's body. At least one recess is formed in one or more areas of the supporting surface, these recesses being open at the peripheral edge of the supporting surface. The table is formed of first and second parts that can be angled relative to one another. The table can be swung horizontally to relative positions relative to the machine and locked in selected ones of the positions.
摘要:
Nuclear Magnetic Resonance imaging apparatus of the type for imaging specific parts of the body, the device including a magnetic structure (1), having a cavity (101) for accommodating the limb part to be examined, which may be accessed from the outside, and in which, or at least in one part of which (V) the necessary magnetic fields are generated. The magnetic structure (1) is supported in such a manner as to be able to oscillate (O) about a horizontal axis, which is parallel to the static magnetic field, whereas the axis of oscillation (O) is staggered with respect to the central axis, which is parallel thereto and passes through the cavity volume (V), wherein the static magnetic field has the characteristics required for valid imaging, to such an extent that the relevant volume (V) moves from an uppermost position to a lowermost position, the two extreme positions as well as those intervening therebetween being adjusted to the head and/or neck and/or upper limbs level in the standing and/or sitting positions of the patient and to the lower limbs level in the standing and/or sitting positions of the patient respectively.
摘要:
A magnetic resonance imaging apparatus including a magnetic structure having two opposite and spaced apart poles and a column or wall transverse to the poles and connecting the poles; the poles defining two opposite walls delimiting a patient-imaging space, the two opposite walls extending along substantially parallel planes which are substantially parallel to a vertical plane; and a patient positioning table which is slidably connected to a supporting frame between the two poles; the table being positioned with its longitudinal axis substantially parallel to the two opposite parallel walls of the poles and the table being oriented with its transverse axis perpendicular to at least one of the two opposite walls.
摘要:
A Magnetic Resonance Imaging apparatus having an open U- or C-shaped magnet structure, wherein the magnet structure has at least one vertical connection member for joining two horizontal wall members which lie one above the other and are supported in a cantilever fashion and in a predetermined spaced relationship by the vertical member, the vertical member being eccentrically connected to the two wall members at a side edge thereof. The horizontal wall members and the vertical member delimit the upper and lower sides and at least a vertical lateral band of a space for receiving at least one part of a patient body. The horizontal wall members also support means for generating a static magnetic field that permeates the patient receiving space. The apparatus further includes a patient table, supported in an intermediate position between the two horizontal wall members, and lies slightly above the lower horizontal wall part, the table being displaceable in at least one displacement direction, having at least one component of motion towards and/or away from the vertical connection member, and the table being rotatable about a vertical axis outside the magnet structure, i.e. outside the horizontal wall members.
