In order to improve local specificity and adjustability of the radiant power in radiation diagnostics and in post-operative radiation therapy, the invention devises an implant system (100, 100, 100, 100) having a structural part (50, 50, 50, 50) that can be implanted in a damaged tissue region (30) and has at least a first region (10a, 10b, 10c, 10d) made of a first material and at least a second region (20a, 20b, 20c, 20d) made of a second material, the first region (10a, 10b, 10c, 10d) being designed to support the structural part (50, 50, 50, 50) and being substantially impermeable to a predetermined radiation for the purpose of diagnostics or for medical radiation therapy, and the second region (20a, 20b, 20c, 20d) being designed to complement the first region (10a, 10b, 10c, 10d) to the structural part (50, 50, 50, 50) and further comprising at least one portion (22a, 2b, 22c, 22d) that is structurally modified. The portion (22a, 2b, 22c, 22d) of the second region (20a, 20b, 20c, 20d) is permeable to the predetermined radiation for the purpose of diagnostics or for medical radiation therapy.

The invention comprises a method and apparatus for treating a tumor using positively charged particles having passed through an intervening object, comprising the steps of: predetermining an energy reduction of the positively charged particles resultant from the positively charged particles traversing the intervening object along a beam treatment path as a function of relative rotation of the patient and the beam treatment path; generating a radiation treatment plan adjusting energy of the positively charged particles delivered from the synchrotron to the intervening object to yield a desired beam treatment energy of the positively charged particles entering the tumor after compensating for the energy reduction; and optionally detecting a set of the positively charged particles after traversing the intervening object to yield a signal, where the signal is used with knowledge of energy of the positively charged particles exiting the synchrotron to pre-determine the energy reduction along the beam treatment path.

An optimization method for ion based radiotherapy includes inverse planning based on optimization variables related to the particle energy, a range modulator or ridge filter, a block and/or a range compensator. This enables automatic optimization of complex cases.

A medical image-based radiation shielding device and method thereof, which may form a targeted and highly accurate radiation shielding according to individual differences in patients, such as tumor location and size, thereby reduce or avoid radiation from a irradiation apparatus to normal tissues of patients. The shielding device includes a medical image scanning means for scanning an irradiated site of an irradiated subject and outputting medical image voxel data, a data processing and three-dimensional modeling means for establishing a three-dimensional phantom tissue model according to the medical image voxel data and establishing a three-dimensional shield model according to the three-dimensional phantom tissue model; a shield located between the irradiation apparatus and the irradiated site, wherein the shield is formed by printing the three-dimensional shield model data input to a 3D printer.

Systems for immobilizing a patient are disclosed. The system includes at least one preform formed from a low melting temperature thermoplastic, the preform being configured to be formed to the anatomy of the patient, at least one frame coupled to the at least one preform, and at least one support configured to support the anatomy of the patient. The system also includes at least one lock mechanism coupled to at least one of the frame and the support and configured to couple the at least one frame to the at least one support, and at least one adjuster mechanism coupled to at least one of the at least one frame and the at least one support and configured to selectively adjust a distance between the at least one frame and the at least one support while the at least one frame is coupled to the at least one support.

Disclosed is a tumor surface dose enhancing radiotherapy apparatus using a magnetic field, including a radiation beam generating unit that irradiates a radiation beam towards a tumor of a patient, a magnetic field generating unit that forms a magnetic field that is parallel to the radiation beam between the radiation beam generating unit and the tumor of the patient, and a control unit that controls a surface dose of the tumor by adjusting an intensity and an effective area of the magnetic field of the magnetic field generating unit.

An implantable device has a body that is substantially rigid and has a predetermined shape. The body is further bioabsorbable and has a density less than or equal to about 1.03 g/cc. When the device is implanted in a resected cavity in soft tissue, it causes the cavity to conform to the predetermined shape. The implantable device is further imageable due to its density being less than that of soft tissue such that the boundaries of the tissue corresponding to the predetermined shape can be determined.

An unlocking assembly and a human body fixing device. The unlocking assembly includes a fixing plate, locking bodies, and a flexible member; the fixing plate is provided with fixing holes; the locking bodies are movably mounted in the fixing holes; the flexible member is connected to the locking bodies and is configured to drive the locking bodies to move towards a direction extending out of the fixing holes. Because the locking bodies are telescopically mounted in the fixing holes located on the fixing plate, and the flexible member can drive the locking bodies to move towards the direction extending out of the fixing holes, locking between the locking bodies and the fixing holes is released only by remotely controlling the flexible member.
