摘要:
The present invention establishes a fast and simple [F-18] FLT synthesis process. Solid extraction units are used for purification to achieve an equally high and constant radiochemical yield and purity in a short period of time. By using a separation method, the impurities are reduced successfully while the total synthesis time is shortened. The radiochemical purity and the corrected radiochemical yield are both high.

A method used to yield irradiation product with minimal impurity for the solid target for gallium (Ga)-68/germanium (Ge)-68 generator mainly consists of the procedures: first calculate the thickness d for the electroplated gallium (Ga)-69 on the solid target; and then through a graph of decay curves including 69Ga(p, 2n) 68Ge target thickness and incident energy with 5 different incident energy doses, derive the corresponding irradiation energy dose Yi for each group after decay; and through the graph including 69Ga(p,2n)68Ge incident energy and reaction cross-sectional area, derive the nuclear reaction cross-sectional area for each group for germanium(Ge)-68, gallium (Ga)-68, zinc (Zn)-65 and figure out the mean reaction area (MRA) from the reaction cross-sectional area of each group; and select the maximum germanium(Ge)-68 MRA value and the minimum gallium (Ga)-68 and zinc (Zn)-65 MRA values; and generate the required default irradiation energy for the MRA of each group.

A method to produce a high-purity Zr-89 on a solid target through physical irradiation and measurement by selecting a target Barn value of the cross-sectional area of nuclear reaction, drawing a horizontal line to intersect at two points on the function diagram curve and drawing a vertical line downward from each of the two points intersecting at X-axis to obtain incident energy values at the two intersecting points on the X-axis, and followed by plotting an attenuation function diagram curve of penetration depth versus incident energy of Y-89(p,n)Zr-89, selecting an attenuation function diagram curve and a minimum attenuation position of the selected attenuation function diagram curve in correspondence to the incident energy in the interval of incident energy absorption range to obtain an optimal plating thickness value on the solid target.

A liquid isotope delivery system includes a pressure-controlling unit, an input unit, a target chamber, a proton-radiating unit and a storage unit. The pressure-controlling unit includes a first regulating valve, a second regulating valve connected to the first regulating valve and a third regulating valve connected to the first regulating valve. The input unit is connected to the second regulating valve. The target chamber is connected to the third regulating valve and the input unit. The proton-radiating unit is located near the target chamber. The storage unit is connected to the target chamber.

A device to rapidly obtain a solution of Pb(lead)-201 from a solution of a solid target material of Tl(thallium)-203. The solution of Pb-201 is then processed through a degeneration and an ion exchange to obtain in Tl-201 radioisotope.
摘要:
The preparation method of radiation-sensitive copolymer carrier for coating radiated nanoparticles and/or chemotherapy drugs includes forming a nanosphere by diselenide block copolymers and DSPE-PEG-biomarkers to coat chemotherapy drugs and/or radiated nanoparticles that can be released from the opened nanosphere by protons penetrating tissue during proton therapy. The treatment effect of proton therapy is enhanced by two ways of using the radiated nanoparticles released from an opened nanosphere to produce nuclear fission with the protons for releasing electrons to destroy cancer cells of tumor and the chemotherapy drugs released from the opened nanosphere for distributing among tissue to kill the cancer cells of the tumor.
