Abstract: Provided is a medical immobilization device that contributes to reducing the burden on a patient, while being capable of firmly immobilizing the patient. A medical immobilization device 10 is a device for immobilizing a specific site 1 of the body of a patient with the patient lying on their back. The medical immobilization device 10 comprises a block 3 made of a material that allows radiation to pass through, and the block 3 comprises holder portions 2a to 2c in which at least a region from the lower surface to both sides of the specific site 1 fit. All or part of the upper part of the block 3 is open.

Abstract: Disclosed is a spacer for radiotherapy that can be easily compressed into a reduced thickness, and has a high capacity to reconstitute itself from a compressed state back to its initial thickness after removal of external force. The spacer for radiotherapy is a flexible structure having front and back main faces and thickness therebetween, and composed of strands of biocompatible and biodegradable synthetic fibers, wherein the spacer consists of (a) a pair of main face portions opposing each other with a gap therebetween and respectively defining the main faces of the structure, and (b) a linker portion linking between the pair of main face portions, (c) wherein the main face portions comprise a knitted-fabric structure or a weave structure made of the strands, and (d) wherein the linker portion is composed as a collection of linker strands formed of the said strands and respectively extending in the thickness direction of the spacer and linking the pair of main face portions with each other.

Abstract: A radiotherapy spacer is disclosed that has both flexibility for allowing it to gently cover the organs of various shapes along their surfaces and pressure resistance for preventing itself from being crushed under the pressure between organs and thus enabling it to retain its own shape and continuously ensure the therapeutic space. The spacer comprises a fiber assembly formed of entangled biocompatible fibers, which may be bioabsorbable, such as nonwoven fabric, and is characterized in that the density of the fiber assembly is 0.05 g/cm3 to 0.2 g/cm3.

Abstract: Provided is a driving apparatus for driving a movable optical member, the driving apparatus being removably attached to a lens barrel, the driving apparatus including: a rotary absolute position detector detecting a position of which the movable optical member, the rotary absolute position detector outputting an output value having a unique value with respect to a rotation angle within a range of a single rotation, and the output value having a point of discontinuity at which the output value is discontinuous every single rotation; and a controller performing boundary processing that handles the output value, corresponding to a driving range of the movable optical member, of the rotary absolute position detector having the point of discontinuity as a continuous value.

Abstract: An automatic focusing apparatus includes: a focus lens unit; a focus driver; a first focus detector that detects an in-focus state based on a phase difference; a second focus detector that detects an in-focus state using a signal from an image pickup element; a focus controller that controls the focus driver to perform focusing based on a first focus detection result and a second focus detection result; a movement detector that detects a movement of an object with components in a direction perpendicular to an optical axis based on an image signal obtained from the first focus detector; and a re-execution determination unit that determines whether to control the focus driver to re-execute focusing based on the first focus detection result and the second focus detection result that are newly detected after the execution of focusing and based on a movement detection result detected by the movement detector.

Abstract: Provided is a radiotherapeutic agent, including a composite particle, which is obtained by binding a molecule that specifically recognizes a target to a substrate particle including titanium peroxide, and which generates reactive oxygen through irradiation with a radiation. Further, because the radiotherapeutic agent contains the molecule that specifically recognizes a target, the radiotherapeutic agent has a function of accumulating in the target. The radiotherapeutic agent is capable of enhancing effects of radiotherapy, and is capable of reducing side effects on a living body to efficiently attack the target.
