Cone-beam computer tomography systems, devices, and methods for image acquisition of large target volumes using partial scans.

Cone-beam computed tomography imaging devices, systems, and methods

A radiation therapy system includes a treatment couch positioning assembly that is directly coupled to a fixed structure supporting the linear accelerator of the radiation therapy system. The radiation therapy system can be installed in a radiation therapy facility without the floor of the facility being excavated and a sub-floor structure, such as a base frame, being installed. To laterally position a patient relative to the linear accelerator, the treatment couch positioning assembly of the radiation therapy system is laterally translated via a linear motor, and laterally translates with the treatment couch, rather than cantilevering the treatment couch to either side of the couch positioning assembly.

Radiotherapy system with linear motor for transverse actuation of base and rotation of gantry

A beam filter positioning device includes a first and a second axes operable to move a body supporting one or more collimators, one or more photon flattening filters, one or more electron foils, and field light mirror etc. The collimators may be configured to collimate radiation to define a treatment beam suitable for radiosurgery. A controller is programmed to control the servo motor of the first and second axes to accurately position the beam filters. Radiation apparatuses and systems incorporating the beam filter positioning device or assembly are also provided.

Internally mounted collimators for stereotactic radiosurgery and stereotactic radiotherapy

An X-ray target assembly includes a substrate, a target supported by the substrate adapted to generate X-rays when impinged by an electron beam, and an enclosure over the target providing a volume for the target. The enclosure is made of a material substantially transparent to electrons. The volume is substantially vacuum or filled with an inert gas.

Target assembly with electron and photon windows

A method of deploying a prosthesis includes engaging a hub assembly of a handle to a threaded outer surface of a slide shaft of the handle; rotating the hub assembly to cause axial translation of the hub assembly and a sheath coupled to the hub assembly to initiate deployment of the prosthesis; disengaging the hub assembly from the threaded outer surface by pivoting a thread tooth of the hub assembly out of threaded engagement with the threaded outer surface; and sliding the hub assembly on the slide shaft to further retract the sheath and complete deployment of the prosthesis.

Integrated mechanical handle with quick slide mechanism

An embodiment of the present invention provides an apparatus for setting a dose of a drug in a syringe having a plunger, comprising an outer housing and an inner housing adapted for encircling the syringe, such that the inner housing is positioned within the outer housing to set the dose of the drug. In an embodiment, the apparatus further comprises a dosage indicator disposed on the inner housing and the outer housing further comprises an opening for viewing the dosage indicator.

Drug delivery system for administering an adjustable preset dose

A delivery system includes a sheath and a handle. The handle includes: a slide shaft having a threaded outer surface; and a hub assembly coupled to the sheath. The hub assembly includes: an inner slider having a thread tooth pivot support; a thread tooth pivotably mounted to the thread tooth pivot support; and a sleeve having a thread tooth press member pressing on the thread tooth, where motion of the sleeve relative to the inner slider pivots the thread tooth on the thread tooth pivot support to engage and disengage the hub assembly with the threaded outer surface.
