Embodiment 1

[0034] CT simulation positioning machine morning inspection, weekly inspection phantom, such as Figure 1-3 with Figure 7 As shown, including a main body 1, the outer walls on both sides of the main body 1 are respectively provided with two identical left and right positioning columns 2, and the two left and right positioning columns 2 are symmetrical about the main body 1; the outer walls on both sides of the main body 1 are respectively provided with Two identical front and rear positioning blocks 7; the top outer wall of the main body 1 is provided with a left and right positioning reference groove 4, and the top outer walls of the main body 1 both sides are provided with a first left and right positioning groove 6, and the top outer walls of the left and right positioning columns 2 are provided with The second left and right positioning reference grooves 3; the top outer walls of the main body 1 and the left and right positioning columns 2 are provided with front and rear...

Embodiment 2

[0045] CT simulation positioning machine morning inspection, weekly inspection phantom, such as Figure 4 As shown, in order to facilitate observation and improve positioning accuracy; this embodiment makes the following improvements on the basis of Embodiment 1: the intersection between the left and right positioning reference grooves 4 and the front and rear positioning reference grooves 13 and each positioning groove and reference grooves Positioning holes 16 are provided at each position, and the positioning holes 16 are in a conical structure; by setting the positioning holes 16 in a conical structure, it is beneficial to observe and further improve the positioning accuracy.

[0046] When this embodiment is in use, when the detection position is close to the intersection between each positioning groove and the reference groove, the positioning hole 16 with a conical structure is conducive to observation and further improves the positioning accuracy.

Abstract

The invention discloses a CT simulated positioner morning-weekly inspection phantom, and relates to the technical field of medical devices. The problem of displacement accuracy during multi-directional inspection operation is solved. The CT simulated positioner morning-weekly inspection phantom specifically includes a body, two same left and right positioning columns are arranged on the outer walls of the two sides of the body correspondingly, and the two left and right positioning columns are symmetrical about the body; two same front and rear positioning blocks are arranged on the outer walls of the two sides of the body correspondingly; and left-right positioning reference grooves are formed in the outer wall of the top of the body, and first left-right positioning grooves are formed inthe outer walls of the tops of the two sides of the body. The detection of the accuracy in the left-right direction can be facilitated by forming the left-right positioning reference grooves, the first left-right positioning grooves and second left-right positioning reference grooves; the detection of the accuracy in the front-rear direction can be facilitated by forming front-rear positioning reference grooves and front-rear positioning grooves; and the detection of the accuracy in the vertical direction can be facilitated by forming horizontal positioning reference grooves, lower horizontalpositioning grooves and upper horizontal positioning grooves.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a phantom of a CT simulation positioning machine for morning inspection and weekly inspection. Background technique [0002] At present, CT is a mature medical technology. In precise radiation therapy, it is necessary to perform CT positioning on patients. Before positioning, it is necessary to test the CT simulation positioning machine to ensure that the machinery and images meet the clinical requirements. The phantom can be used for morning inspection and weekly inspection of CT simulation positioning machine, machinery and some images, etc., and has achieved the purpose of quickly and accurately completing quality assurance and control. [0003] After searching, the Chinese patent application number is CN201821529371.9, which discloses a multifunctional CT / PET phantom, which is characterized in that it includes a hollow phantom rear end, and the phantom front end is ...
