The present invention relates to a body insertable device having an outer body being bent; and an inner body positioned inside the outer body, having an accommodation space in which the resource soured is accommodated, and being capable of rotating inside the outer body, wherein a radiation emission direction is continuously adjusted by rotation of the inner body.

A method and system may include a therapeutic agent having a radioactive source enclosed by a container. The container may be placed within a cavity of a medical device for treating animal tissue. The method and system allows a radioactive source to be manufactured in such a manner so as to control and spatially modulate the delivery of radiation doses to a treatment area of animal tissue, such as for tissue of humans. From the container, radiation doses and/or a radiation field are produced by the radiation source. The geometry and size of the radiation doses are controlled by the geometry of the container and the geometry of the radiation source as well as the type, number, and geometry of holes/slots in either the source material and/or a surface of the container.

The invention relates to a magnetic resonance imaging system (100). The magnetic resonance imaging system (100) is configured to be selectively operated in a default mode and an emulation mode. Execution of machine executable instructions (290) by a processor (203) of the magnetic resonance imaging system (100) causes the magnetic resonance imaging system (100) to receive a selection signal selecting the emulation mode. The magnetic resonance imaging system (100) switches from the default mode to the emulation mode. The magnetic resonance imaging system (100) is operated in the emulation mode using the set of emulation control parameters (292). The emulated magnetic resonance imaging data (270) is acquired from the imaging zone (108) of the magnetic resonance imaging system (100).

A body-insertable device having an adjustable radiation emission direction and radiation emission range, which includes a first outer body extending to be long and an accommodation space having a first accommodation space and a second accommodation space having different distances to the first outer body.

This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device includes a stent having a first strut. The first strut may include an inner surface and an outer surface. The medical device may also include a first attachment member coupled to the strut and a radioactive element. The radioactive element may be coupled to the attachment member.

A design, quality assurance, and clinical use procedures are provided for real-time tracking of a custom MRI/CT-compatible brachytherapy applicators. A real-time tracking system is used for applicator implantation, repositioning and tracking during treatment delivery.
