Abstract: Systems are disclosed for patient positioning in radiotherapy. A patient support system comprises a base (314,328), a linear guide comprising a bearing (908,910) and an elongate bearing guide (316,410,420,902,904) arranged to guide translational motion of the bearing (908,910) along a translation axis, and a patient support surface (114,312) coupled to the base (314,328) via the linear guide, the linear guide being arranged to guide linear motion of the patient support surface (114,312) relative to the base (314,328) in a direction parallel to the translation axis. The patient support system comprises a safety guide (600) having a safety guide end adjacent to one end of the elongate bearing guide (316,410,420,902,904), wherein an open channel (610) defined by a surface of the safety guide (600) starts at the safety guide end with an open part of the channel (610) facing the translation axis, and a depth of the channel (610) tapers away from the elongate bearing guide (316,410,420,902,904).

Abstract: A controller (600) for a radiotherapy device (320) is provided; the radiotherapy device (320) being configured to provide therapeutic radiation to a patient (308) via a source (300) of therapeutic radiation, wherein the radiotherapy device (320) comprises a first rotatable member (304), the rotation of which can alter a physical attribute of the therapeutic radiation provided, and a patient support member (310), which is linearly moveable in at least one of a longitudinal direction and a lateral direction. The controller (600) comprises a first rotatable actuator (608) for controlling a movement of the first rotatable member (304) and a second actuator (620) for controlling a movement of the patient support member (310).

Abstract: This invention disclosed an anti-HPV drug and its applications in preparing medicines for treatment of HPV (human papilloma virus) infection. This drug was characterized by using human rabies vaccine as its active ingredient and being produced by adding pharmacologically acceptable carriers. This invention also disclosed drug applications in preparing medicines for treatment of HPV infection, i.e. new applications of human rabies vaccines for preparing medicines against HPV infection. The anti-HPV drug described in this invention (i.e. human rabies vaccine) had obvious treatment effects on HPV infection. According to the animal tests and preclinical observation, this drug provided satisfactory and beneficial effects and had the characteristics of safety, effectiveness and nearly no recurrence after treatment; the negative-conversion rate in patients with positive HPV-infection reached 90% after treatment.
