| Summary: | A wire mesh collimator (10) is proposed as an alternative to the multihole collimator of a gamma camera. The wire mesh collimator (10) comprises round wires that are used to form septa (12) of a wire mesh. Each septum (12) has a predetermined diameter and spaced apart at a distance same as the diameter of the septa. The first embodiment of the wire mesh collimator (10) has a uniform diameter of septa and distance between septa. For a collimator depth of 4 cm, the septa have a diameter of 0.02 cm and the distance between each septum is 0.02 cm. The second embodiment of the wire mesh collimator (10) has walls on the gamma ray entry point and exit point. Walls are created by stacking at least three septa together. For a collimator depth of 4 cm, seven septa having a diameter of 0.02 cm are stacked together to form an entry wall. Seven septa having a diameter of 0.02 cm are also stacked together to form an exit wall.
