A plurality of wall cells rest upon an underlying cementitious foundation and form a perimeter of the vault. Each wall cell has two lateral sides with mating surfaces thereon which are of complementary undulating shape with adjacent lateral surfaces of adjacent wall cells. The wall cells have different thicknesses and widths to provide desirable wall thickness for a different portions of the oncology vault. A door assembly formed of specialized wall cells and with a pivoting door element are also included within the wall. A ceiling is provided above space inboard of the wall cells. This ceiling is formed of separate ceiling slab elements. The slabs are stacked in at least one layer. In one embodiment, multiple layers of slabs are stacked with seams between slabs of each layer offset from each other. In another embodiment, lateral sides of the slabs have a complementary undulating shape.

The radiotherapy applicator system includes an applicator pad adapted to cover a target area of a patient for radiation treatment. One or more spaced channels extend through a length of the applicator pad. Each channel receives a catheter sleeve, and an elongate seed line is selectively inserted into a corresponding catheter sleeve. Each seed line contains one or more radioactive seeds and spacers arranged in a predetermined pattern along the length of the seed line. The seed lines within the applicator pad form an array of a predetermined, geometric treatment pattern of seeds covering the target area, the treatment pattern predetermined from a treatment plan for that target area and the patient. Shielding is provided to protect staff administering the treatment and non-target areas from harmful levels of radiation exposure. The radiotherapy applicator system is reusable for multi-session treatment and may be provided as a customized kit.

A system includes a connector with a central lumen. A multi-lumen chamber is removably connected to and in fluid communication with a proximal end of the central lumen. The multi-lumen chamber includes a first lumen aligned and adjacent a second lumen. The first lumen includes a first fluid in a proximal portion of the first lumen and a hydrophilic polymer in a distal portion of the first lumen, a first plunger rod within the first lumen to control flow of the first fluid into the distal portion to mix with the hydrophilic polymer in a first state to form a first mixture, and a first port. The second lumen includes a second fluid, a second plunger rod within the second lumen to distally move the second fluid and the first mixture in a second state, and a second port.

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.

The radiotherapy device includes a radiation source apparatus having a plurality of radiation sources, a source carrier and a collimator. The source carrier includes a source box and a source box region conforming to a shape of the source box, the source box is detachably fixed at the source box region, the plurality of radiation sources are mounted in the source box, the source box is provided with a first connecting part, the source carrier is provided with a second connecting part, and the first connecting part is configured to connect the second connecting part.

The present invention provides a radioactive patch comprising a layer of a mixture of a radionuclide with a nonreactive adhesive agent coated thereon in the form of a tape, and a laminating layer, wherein the patch comprises, a high Z shielding layer placed on the opposing side of the patch away from the patient tissue, and comprising at least one of: lead, tungsten, iron, silver, gold, platinum, copper, brass; and wherein the patch comprises, a low Z shielding layer comprising at least one of: teflon, pma, pvc, lucite, boron carbide, graphite, carbon fiber, bakelite; and wherein the radionuclide comprises at least one of: Y-90, Ho-166, LU-166, I-125, PD-103, LU-166, or any combination thereof.

Disclosed is a radiation and magnetic field generating apparatus irradiating photon beam radiation to in-body affected tissue of a subject. The apparatus includes a radiation generating unit that irradiates the photon beam radiation to the subject and induces generation of secondary electrons in an area of the subject where the photon beam radiation is irradiated, a magnetic field generating unit that includes an insertion structure for forming a low-density space and forms a magnetic field in an area in which the secondary electrons are generated, and a synchronization control unit that controls formation of the magnetic field and controls the formation of the magnetic field such that the secondary electrons move while avoiding normal tissue adjacent to the affected tissue.

The present invention provides radioactive dermatological patch designed to topically treat cutaneous skin lesions in patient tissue. The radioactive dermatological patch includes a layer of a radionuclide with a nonreactive binding agent to form a treatment wafer. The treatment wafer is then placed within the radioactive dermatological patch. The radioactive dermatological patch includes a high Z distal shielding layer placed adjacent the side of treatment wafer away from the patient tissue. The distal shielding layer attenuating the energy of the radionuclide from the environment external to the patient. The patch further includes a high Z proximal patient shielding layer placed between the patient tissue and treatment wafer.

Methods for setting up, maintaining and operating a radiopharmaceutical infusion system, that includes a radioisotope generator, are facilitated by a computer of the system. The computer may include pre-programmed instructions and a computer interface, for interaction with a user of the system, for example, in order to track contained volumes of eluant and/or eluate, and/or to track time from completion of an elution performed by the system, and/or to calculate one or more system and/or injection parameters for quality control, and/or to perform purges of the system, and/or to facilitate diagnostic imaging.

A replaceable cartridge can be used in a system for providing a radiation source for brachytherapy. The cartridge configured to be received into a base defining a receptacle. The cartridge can comprise a radiation source. A shield can be configured to receive the radiation source. A guidewire can be coupled to the radiation source. At least one motor can be configured to move the guidewire to thereby adjust the position of the radiation source.
