Embodiment

[0106] Example: Combined Photodynamic / Radiation Therapy for Breast Cancer

[0107] 1) First, use various diagnostic equipment and testing techniques to determine that the patient has breast cancer, obtain information such as the nature, type and degree of breast cancer, and the doctor formulates a comprehensive treatment plan for surgery and radiotherapy.

[0108] 2) CT scanning is performed on the patient to obtain anatomical images of breast cancer and surrounding organs at risk and normal tissues. The doctor outlines the target area and organs at risk, calculates the dose, and at the same time determines the prescribed dose of the target area and the tolerated dose of the organs at risk.

[0109] 3) The physicist uses the radiotherapy planning system to set various parameters in the combined treatment according to the swollen target area drawn by the doctor, the outline of the organ at risk and the prescribed dose, combined with the patient's anatomical image, mainly includi...

Abstract

The invention discloses a deep tumor treatment system for photodynamic combined radiotherapy. A low-dosage CT imaging device carries out scanning and imaging on a treated object to obtain information of a spatial position, a size, and a surrounding important structure of a tumor. A deep tumor photodynamic therapeutic device injects a specific X-ray excited photosensitizer into the treated object by intravenous injection and the photosensitizer is collected at a tumor tissue; after X-ray excitation, singlet oxygen is generated; and the deep tumor is processed by photodynamic therapy. A radiotherapy device formulates a radiotherapy scheme meeting a treatment requirement to carry out radiotherapy on the tumor tissue. A deep tumor photodynamic/radiotherapy combined device can carry out photodynamic and radiotherapy processing on the tumor tissue simultaneously. According to the invention, the photodynamic/radiotherapy combined treatment can be carried out on the tumor tissue according to a set parameter and independent photodynamic or radiotherapy treatment can be realized. Therefore, the treatment effect of the deep tumor in the human body can be improved and the exposure dosage on the normal tissue can be reduced effectively.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a deep tumor treatment system of photodynamic combined with radiotherapy. Background technique [0002] (1) Radiation Therapy [0003] Tumor radiation therapy (referred to as radiotherapy) is a technology that uses various ray beams (such as α-rays, X-rays and electron beams) to treat malignant tumors. Tissues are not damaged and violated by radiation. However, the radiation dose of radiation therapy is large (usually 60-80Gy), which will cause serious side effects, such as radiation inflammation, hair loss, blood cell damage, etc., and it is not suitable for the treatment of multiple, metastatic, and radiation-insensitive tumors. [0004] With the development and progress of radiation therapy technology, three-dimensional conformal radiation therapy, intensity-modulated radiation therapy, and volumetric dynamic intensity-modulated therapy can achieve a sign...
