Title:
MEASUREMENT DEVICE AND MEASUREMENT METHOD FOR SPATIAL RESOLUTION OF PET SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/128316
Kind Code:
A1
Abstract:
A measurement device and measurement method for the spatial resolution of a positron emission tomography (PET) system, wherein the measurement device comprises a prosthesis (10); a plurality of injection holes (20) are arranged on a surface (11) of the prosthesis (10); and the prosthesis (10) is also internally provided with a plurality of injection channels (30) and a plurality of storage spaces (40), wherein the storage spaces (40) communicate with the injection holes (20) by means of the injection channels (30), and the volumes of the storage spaces (40) are divided into at least one level; the measurement method comprises: using an injection tool to inject a detection agent into the plurality of storage spaces (40) in the prosthesis (10) by means of the injection channels (30), wherein the volume of the detection agent injected into each of the storage spaces (40) does not exceed the volume of the corresponding storage spaces (40); using a proton radiotherapy equipment to shine a proton beam towards the detection agent in the prosthesis (10); using a PET system to detect a detection agent that is currently being subject to proton beam irradiation or that has completed irradiation, and acquiring corresponding flickering pulse data; carrying out signal processing and image reconstruction according to the flickering pulse data, and analyzing the spatial resolution of the PET system.
