    摘要: In accordance with the embodiments of the present disclosure, a rack comprising a frame having first vertical posts on a first side and second vertical posts on a second side, between which a plurality of RF amplifier modules are mounted, is provided. The RF power outputs of the RF amplifier modules are connected to inputs of an RF power combiner to deliver a combined RF power output. The RF power combiner is arranged at least partially in at least one of a first volume between the first vertical posts of the frame or a second volume between the second vertical posts of the frame, thereby reducing a footprint of the rack.

    摘要: The invention relates to a method for quality assurance of a radiation field (30) emitted by a radiation therapy apparatus (10), comprising the steps of: (i) providing an ionization chamber (40) detector as reference detector for measuring the dose of the radiation field (30) at the exit of the radiation head (20), said ionization chamber (40) having a size and being positioned for being traversed by said radiation beam (30), said ionization chamber (40) having an attenuation equivalent to less than 1 mm Al; (ii) providing one or more field detectors (50); moving the field detector (50) across the radiation field (30) and measuring simultaneously the dose from the field detector (50) and from the ionization chamber (40); (iii) computing the ratio of the dose from the field detector (50) to the dose of the ionization chamber (40). The invention also relates to a device for performing the method.

    摘要: The present disclosure relates to an apparatus for the synthesis of chemical compounds, e.g., radiopharmaceutical compounds. In one implementation, the apparatus may include a synthesis module and a loading module configured to receive multiple chemical cassettes having reagents and a transfer mechanism. The apparatus may further include a shifter configured to move the cassettes from a location on the loading module to a location connected to the synthesis module on an interface configured to connect to the cassette.

    摘要: The present disclosure relates to compact isochronous sector-focused cyclotrons having reduced dimensions and weight compared with state of the art cyclotrons of same energies. In one implementation, a cyclotron may include two pole magnets facing each other in a chamber defined by a yoke having base plates and flux return yokes forming a lateral wall of the chamber. The magnet poles may include between three and eight hill sectors alternating with a same number of valley sectors distributed about a central axis. The lip of the abyssal opening may be positioned at a distance from the corresponding valley peripheral edge. The flux return yoke may have a thickness in the portions facing valley sectors, such that the ratio of the product of the distance times the thickness to the square of the distance of the peripheral edge to the central axis is less than 5%.
