Clinical rapid acquisition, guide registration method and system

Abstract

The invention relates to the technical field of nuclear medicine, and particularly relates to a clinical rapid acquisition guide registration method and system, and the method comprises the steps: enabling a nuclear medicine equipment detector to acquire a projection image of a target organ moving in unit time when nuclear medicine equipment guides CT collection, and extracting the movement trackof the target organ according to the projection image; calculating the absolute position of the target organ in a space coordinate system according to the motion trail; adjusting the nuclear medical equipment detector according to the absolute position of the target organ in the space coordinate system until the nuclear medical equipment detector is at the optimal position; and, enabling the nuclear medicine equipment detector to collect the target organ according to a preset collection condition, so the problem that a multi-pinhole collimator only has a virtual focal center and a system (collimator) installation error, and consequently the position of the multi-pinhole focal center deviates from the position of a theoretical focal center is solved, and it is guaranteed that during actualclinical application, formal collection is conducted after the multi-pinhole collimator is accurately aligned with a target organ, and the effectiveness of image collection is guaranteed.

Description

technical field [0001] The invention relates to the technical field of nuclear medicine, in particular to a method and system for clinical rapid acquisition-guided registration. Background technique [0002] The traditional parallel hole collimator has poor resolution and sensitivity, and needs to be rotated at multiple angles during the acquisition process, which cannot meet the fast requirements of dynamic acquisition of cardiac blood perfusion (complete a reconstruction in 20s-60s). Compared with the tomographic acquisition of the parallel hole collimator that needs to be rotated, the multi-pinhole collimator can realize the acquisition of multiple angle information at one time in the case of static acquisition, without rotation, and is safer and more reliable. Due to its high sensitivity and high resolution, it can realize cardiac perfusion acquisition when targeting small organs in clinical applications. Through the combination of multi-pinhole collimator and different...
