15. The patients rare disease was treated using novel techniques developed at the medical school.
Using novel techniques: INCORRECT. This modifier is dangling, since the sentence contains no noun that is properly modified by using novel techniques. To fix the sentence, we can introduce an agent who actually used the novel techniques (e.g., a doctor), or we can switch to a prepositional phrase, such as through the use o fnovel techniques, that does not contain an -ing verb form.
Developed at the medical school: CORRECT. This past participle modifies techniques. Correction: The patient’s rare disease was treated through the use ofnovel techniques devel oped at the medical school.

以上是原文及曼哈顿给的解析。我的疑问是：
through the use of .....加了through后，因为介词短语既可以修饰名词，又可以修饰动词
所以，这个部分修饰的是treated？还是disease？它代表的成分是？
感谢大神解答！
