Rotational exposures from Canon Alphenix cause skin dose map TypeError

[David Platten]

The problem is that the following line has int(frame), and for the system in question this field is None:

    if 'Rotational' in run_type:
        self.my_dose.addDose(skinMap.rotational(x_ray, angle_x, end_angle, int(frames), self.phantom, area, ref_ak,
                                                kvp, filter_cu, d_ref,
                                                self.table_length, self.table_width,
                                                self.table_trans,
                                                self.table_thick + self.matt_thick))

I’m going to get hold of an example RDSR from the system which includes a rotational exposure and see if the number of frames is stored in a non-standard location.

Here’s an example entry from my celery default.log file:

Try to calculate number of frames in an exposure by dividing exposure time by pulse width if number of frames is not available. This works for rotational exposures from our Canon Alphenix Sky+ system. Refs issue #942

Resolving merge conflict. Refs issue #942

→ <<cset 2c95c0df98f9>>

[David Platten]

Added a Canon Alphenix Sky+ RDSR anonymised study which includes a rotational exposure. Refs issue #942

→ <<cset 103dfef628ad>>

[David Platten]

Added test to ensure that a skin dose map is successfully calculated for an RF RDSR which includes a rotational exposure. Refs issue #942

[David Platten]

Inserting decorator to enable the rotational test to be skipped - not sure if this will work on Bitbucket, but it works locally. Also ran PyCharm's 'optimise imports'. Refs issue #942

→ <<cset d81e1f851d57>>

[David Platten]

Replacing skip with a tag of 'slow'. Updated bitbucket-pipelines.yml so the 'test' item excludes any tests tagged with 'slow', and added an item that will just run tests tagged with 'slow'. Refs issue #942

→ <<cset 4b16d27f67c1>>

[David Platten]

Adding option in the pipelines to run the slow tests. Refs issue #942

Added in manual triggers. Refs #942

Renaming test steps to make it clear what they do. Refs issue #942
