A cradle position sensing mechanism that includes a scale unit having a scale, which is used to detect the position of the cradle, formed thereon and being extended to cover a sliding range within which the cradle can be slid; and a sensor unit that moves in the directions, in which the scale unit is extended, along with the slide of the cradle so as to detect the scale of the scale unit. The cradle position sensing mechanism serves as a digital linear encoder. Based on the reading on the scale detected by the sensor, the cradle position sensing mechanism calculates the position into which the cradle is slid.

Subject moving apparatus and imaging apparatus

It is intended to implement imaging in an efficient way. In a first period in which a cradle unit is driven under acceleration from a stationary state, the cradle unit is driven with a constant first torque value. In a second period which comes after the lapse of the first period and in which the cradle unit is driven under acceleration, the cradle unit is driven with a constant second torque value which is smaller than the first torque value.

Imaging apparatus and subject moving apparatus

The present invention is intended to readily move a transfer board from a stretcher to a radiographic table and to efficiently achieve radiography. The transfer board moved from the stretcher is borne by an intermediate table. The transfer board borne by the intermediate table is moved to the radiographic table by an intermediate table mover, and then borne by the radiographic table.

Radiography system and transfer board moving apparatus

With the object of, when a table unit is moved downward as viewed in a vertical direction by use of an actuator, smoothly moving the table unit and enhancing operability, when the actuator moves the table unit from a first position in the vertical direction to a downward second position, a pressure controller adjusts the amount of fluid held in the actuator on the basis of the first position of the table unit, detected by a position detector to thereby control pressure based on the fluid.

Imaging apparatus and subject moving device

An X-ray distribution adjusting filter apparatus for supplying a desired X-ray intensity distribution or adjusting the X-ray distribution to a desired profile, the bowtie filter as the X-ray distribution adjusting filter apparatus has a fixed section having a base portion and inclined portions, first and second movable sections configured to be tiltable pivoting on a center point, and first and second deformable sections whose cavities defined by the fixed section, the movable sections and an expansible bellows is to be filled with fluid, wherein the inclined faces of the fixed section and the flat faces of the movable sections are caused to approach or move away from each other by the tilting of the movable sections pivoting on the center point to vary the quantity of the fluid in the cavities of the movable sections, and to vary the sectional shape of the X-ray absorbing portion of the bowtie filter.

For the purpose of providing a parallel-link table that is moved up/down without moving the position of a subject in the longitudinal direction, an upper structure is placed over a base plate connected with a platform via parallel links, and a first bracket on the upper structure and a middle point of one parallel link are connected by a first position correcting link of a length half that of the parallel link using pivotal joint portions; and therefore, when the base plate is moved up/down with respect to the platform, the upper structure moves only in the vertical direction without moving in the horizontal direction, and the top plate over the upper structure, hence, the subject placed on the top plate can be moved up/down in the vertical direction without moving in the longitudinal direction.

Parallel-link table and tomographic imaging apparatus

For the purpose of always keeping the positional relationship fixed between a support section for supporting a supported object and a base section for receiving the support section, the present apparatus comprises: a support section for horizontally supporting a supported object; a base section having a horizontal plane on its top; and a position adjusting section provided between the support section and the base section, for moving the support section forward/backward between a position above the horizontal plane and a position off the horizontal plane while keeping the support section at a level higher than the horizontal plane, and for moving the support section upward/downward between a position higher than the horizontal plane and a position lower than the horizontal plane at the position off the horizontal plane.

In order to provide an aperture position adjusting mechanism in an X-ray CT system with low cost and high accuracy to enable stable reconstruction of X-ray tomographic images, a first shaft ( ) is provided with a bore ( ) at a position offset from a center axis, and is rotatably supported by a base plate ( ) orthogonally to a pair of rails ( ). A second shaft ( ) is received and is rotatably supported within the bore ( ) through the first shaft ( ). The aperture ( ) is moved along the rails ( ) as the second shaft ( ) is eccentrically rotated by a motor ( ) and, following the eccentric rotation and in a direction opposite to that of the rotation, the first shaft ( ) is eccentrically rotated around the center axis of the bore ( ).
