Embodiment Construction

[0024] In the following, the substantive features and remarkable progress of the present invention will be further clarified through description in conjunction with the accompanying drawings.

[0025] 1. Adjustable positioning rod ( figure 2 ) consists of main rod, auxiliary rod and the probe at the end of the auxiliary rod, the main material is non-magnetic material (common plastics, wood all can), and the positioning rod terminal probe 2 is a material (such as aluminum film) with high reflection coefficient. Make a through hole on one side of the non-magnetic bed, insert the main rod of the positioning rod into the through hole and design appropriately (as the present invention adopts the attached image 3 design structure) so that it cannot be rotated arbitrarily, but it can be stretched along the vertical direction of the bed length; the auxiliary rod 3 is connected with the main rod 4 through the fastening screw 9, and the position between the auxiliary rod and the main r...

Abstract

The invention discloses multi-point scanning positioning system and method for a heart magnetic graph instrument. The system comprises an adjustable positioning rod, a reflective infrared detection module, a scanning bitmap substrate and a microprocessor module (MCU), wherein the end of the adjustable positioning rod is provided with a reflective probe, and the movement of a non-magnetic bed in the horizontal direction can be mapped; the reflective infrared detection module contacts the reflective probe of the positioning rod and is used for detecting whether the probe is positioned above the module by using the reflection mechanism; the scanning bitmap substrate is used for arranging fixed infrared emitting/receiving module according to the specific distribution; and the microprocessor module is used for detecting the state of a receiving tube on the infrared emitting/receiving module and identifying and sending a potential signal to heart magnetic processing software. The method comprises the following steps of: firstly regulating the non-magnetic bed and the positioning rod; referencing a heart position according to known reference points; moving the non-magnetic bed by using an infrared emitting/receiving pair tube and a single chip; positioning a plurality of lattices to completely aligning the lattices to position points above the heart to be tested, and collecting signals of the position points through a magnetic sensor so as to acquire a complete heat magnetic signal.

Description

technical field [0001] The invention relates to a multi-point scanning positioning system and a positioning method for a magnetocardiograph. Background technique [0002] Magnetocardiogram (Magnetocardiogram, MCG) instrument is a new type of non-invasive, non-contact, high specificity cardiac diagnosis and treatment equipment. The magnetocardiograph uses an extremely sensitive superconducting quantum interference device (SQUID) as a magnetic sensor to scan the magnetic signals of multiple points in a certain area above the human heart, and perform magnetic information imaging on the heart [Liu Yajun, Huang Hua , Liu Rui, Wu Hong. Principle and Application of Superconducting Magnetocardiograph. China Medical Equipment. Volume 24, Issue 4, 2009]. [0003] To perform magnetic imaging of the human heart, it is necessary to collect magnetic signals at multiple points in a given area (such as 200mm×200mm) on the plane above the heart. The number of sampling points determines the ...
