Body surface marking method and device with real-time image guidance

Abstract

The invention discloses a body surface marking method and device with real-time image guidance. The method comprises the steps of allowing an image processing unit to acquire a marking region medicalimage, determining a marking point, and acquiring positional information of the marking point, positional information of a positioning point and body surface outline information; allowing a photographic unit to acquire a marking region real-time image, and acquiring positional information of the positioning point in the real-time image; acquiring the position of the marking point in the real-timeimage according to the position of the positioning point in the medical image and its position in the real-time image; allowing a camera to continuously acquire a real-time image, adding information of the marking point through the image processing unit, transmitting the information to a display unit, and operating a marker to move so that marking is finished. The real-time image is used to trackthe marking of the marker, and the marker can be guided to move to the marking point just by acquiring the medical image of a marking region once. The existing manner of manually adjusting the position of a developed object and repeatedly acquiring medical images is replaced, patients and doctors take radiation fewer times, equipment is used less frequently, and less radiation injury is caused.

Description

technical field [0001] The invention relates to a real-time image-guided body surface marking method and device, and belongs to the field of marking point marking positioning in minimally invasive surgery with the cooperation of a medical imaging system. Background technique [0002] Medical imaging technology is a science that extracts information about the shape, structure, and certain physiological functions of tissues or organs in organisms by means of the interaction between certain energy and organisms, and provides imaging information for biological tissue research and clinical diagnosis. The scope involved is getting wider and wider, including X-ray imaging, ultrasonic imaging, magnetic resonance imaging, infrared imaging, radionuclide imaging, optical imaging, electrical impedance imaging, etc. [0003] Traditional minimally invasive surgical body surface marking usually uses items such as blades and needles for development to mark the positions of the marking point...

Problems solved by technology

In this process, each time the developing object is moved, it needs to be irradiated once. Both the patient and the doctor need to be exposed to unnecessary ray radiation. Patients who receive over-irradiation may easily cause health risks, and doctors who are over-irradiated for a long time are also prone to corresponding occupational diseases.
