Abstract: A computer-implemented method for managing Cone Beam Computed Tomography, CBCT, imaging of a patient. The method comprises acquiring (102) radiotherapy treatment plan, RTP, information for a RTP. The RTP is for delivering a radiation dose distribution to the patient so as to respect at least one radiotherapy treatment objective. The method further comprises determining (104), based on the acquired RTP information, a measure of sensitivity of the RTP to changes in anatomy of the patient. The measure of sensitivity is a function of position in the patient or a function of radiotherapy beam direction in the RTP. The method further comprises generating (106), based on the determined measure of sensitivity, an imaging protocol for obtaining a reconstructed CBCT image of a volume of the patient by setting a value of at least one parameter in the imaging protocol such that image quality of the reconstructed CBCT image of the patient volume meets an image quality objective for an image processing task.

Abstract: A method for reconstruction of 3D image of a patient is disclosed. The method comprises obtaining a projection set comprising a plurality of 2D CBCT projections of a first volume of the patient, and obtaining a 3D image of a second volume of the patient, wherein the second volume of the patient at least partially overlaps with the first volume of the patient. The method further comprises using acquisition information relating to the obtained projection set to generate, from the 3D image, synthetic projections of the second volume of the patient, and extending the projections of the first volume of the patient from the obtained projection set with information from the synthetic projections of the second volume of the patient. The method further comprises using the extended projections to generate a 3D image of a third volume of the patient, the third volume comprising a combination of the first and second volumes.

Abstract: The mobile fluid delivery system includes a mobile pedestal and a fluid delivery superstructure detachably connected to the pedestal. The fluid delivery superstructure includes a pump device and a fluid control device. A fluid path set operatively associates the pump device with the fluid control device. The superstructure is further adapted to detachably connect to a patient examination platform. A rail mount is used to provide the interface between the superstructure and the patient examination platform. The rail mount attaches to a rail of the patient examination platform and includes a main body defining an elongated recess for engaging the rail of the patient examination platform. The superstructure detachably connects to the main body. Locking devices are used to secure the rail mount to the patient examination platform and the superstructure to the rail mount. A spacer may be inserted into the elongated recess to accommodate different sized rails.

Abstract: The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.

Abstract: A closure which permits the opening of a membrane seal of an enteral nutritional product container in a single-action motion while maintaining product sterility. This closure includes a general cylindrical side wall having threads along the inner surface thereof, a planar top surface having first and second upwardly extending projections. The first projection is associated with a filter means for allowing air to enter the container, while the second projection has a base which is a spikable membrane. A bottom surface having an annular raised portion is provided. The bottom surface has a downwardly projecting plow member as well abutting against gasket means positioned between the annular raised portion and the inner surface of the side wall.
