摘要：
A support unit (200), a support device (100), and an emission tomography device using the support device (100). The support unit (200) comprises: a support main body (210), in which an accommodation space (220) that penetrates through the support main body is provided, comprising multiple support positions (230A, 230B) that are distributed along a circumferential direction of the accommodation space (220) and multiple fastening devices (240A, 240B), connected to at least some of the multiple support positions. At least some of the multiple fastening devices (240A, 240B) can move between a contraction position and an extension position along a radial direction of the accommodation space (220). The fastening devices (240A, 240B) are used to fasten a detector of the emission tomography device. When the fastening devices (240A, 240B) are located at the contraction position, a first detector fastening ring of a first diameter is formed, and when the fastening devices (240A, 240B) are located at extension position, a second detector fastening ring of a second diameter that is smaller than the first diameter is formed. The emission tomography device using the support unit (200) can adjust at least a radial length of a detection cavity, so that a relatively large tree-dimensional space angle can be obtained, thereby improving detection sensitivity.Linvention concerne une unité de support (200), un dispositif de support (100), et un dispositif de tomographie par émission utilisant le dispositif de support (100). Lunité de support (200) comprend : un corps principal de support (210), ledit corps principal de support comprenant un espace de réception (220), comprenant plusieurs positions de support (230A, 230B) qui sont réparties le long de la direction circonférentielle de lespace de réception (220) et plusieurs dispositifs de fixation (240A, 240B) reliés à au moins certaines desdites multiples positions de support. Au moins certains desdits multiples dispositifs de fixation
